9 What is ANM? (1) Definition of ANM > Using flexible network customers autonomously and in realtime > to increase the utilisation of network assets without breaching operational limits > thereby reducing the need for reinforcement, speeding up connections and reducing costs Conventional connection > Standard means of connecting customers to the distribution network > No ANM-based curtailment forming part of the connection agreement ANM connection > Offered on constrained distribution network > Connection conditional on ANM being able to curtail the customer s import or export to alleviate constraint 9 The Voice of the Networks

10 What is ANM? (2) > Function Manage network constraints Maintain networks within their normal operating parameters > Timing Both pre-fault and post-fault applications are considered > Monitoring & information Monitor the state of the system in real-time (or close to it) > Autonomy Minimal real-time human intervention Manual change to future ANM behaviour (e.g. set-points) > Location Can be decentralised, centralised, or a hybrid approach > What ANM controls Guide considers connected customers such as generators, demand or storage Definition can be extended to include DNO-owned network assets 10 The Voice of the Networks

11 What are the application & drivers? > Providing connections quickly and cheaply > Facilitating renewables Enabling faster & cheaper connections > Connect in advance of a reinforcement > Allows for a quicker connection > May be temporary or enduring > ANM may be cheaper than conventional reinforcement > Customers also need to consider cost of curtailment and any (shared) cost of future reinforcement Key drivers Applications considered 11 The Voice of the Networks > Managing intermittent low-carbon technologies > Reducing capital expenditure > Technological readiness Using existing customers to maximise network utilisation > Flexibility of existing demand/ generation can flatten network peaks > Can allow general reinforcement to be deferred or avoided > Commercial decision for the network operator based on the relative costs and benefits

12 Using existing assets to maximise network utilisation DNOs & DUoS Customers Flexibility providers Enabling faster & cheaper connections DNOs & DUoS customers Connected customers Benefits, costs & risks Direct benefits & incentives > Reduced connection costs > Additional revenue from connecting more quickly Costs & risks > Increase in expected curtailment > Long-term risk of increasing curtailment over time > Connection incentives such as customer service, time to connect and customer engagement > Some wider reinforcement costs could be reduced > Financial incentives for flexibility providers (e.g. availability and utilisation payments) > Socialised ANM setup costs > Increased complexity could affect outage rates and restoration times > Reduced opportunity for planned outages > ANM interoperability may increase network risk > Actual loss of earnings (e.g. from core business activities) could exceed expectations > For backup, increased risk of loss of service > Value from delaying or optimising reinforcement capex > Reduced risk of stranded assets > DUoS customers share benefit via efficiency incentives > Cost of finding customers and negotiating > Installing ANM and wider system integration > Payments to flexibility providers 12 The Voice of the Networks

17 Enabling faster & cheaper connections: Principles of access > LIFO may be preferred where early projects are looking for certainty and simplicity > Pro-rata may be preferred where maximising connections is an objective and applications are reasonably concurrent > The chosen approach may differ across a network > Connecting customers need this information up front in order to assess their projects In particular, any obligations (e.g. paying for future reinforcement) LIFO Pro-rata 17 The Voice of the Networks

18 Enabling faster & cheaper connections: Curtailment assessment Key Factors Generation and Demand Network Constraints Principles of access Network topology Comms Impact Existing profiles and future growth / decline Curtailment will vary with the network topology POA and place in the queue will affect curtailment Curtailment will vary with the network configuration Reliability of communications will affect curtailment > Customers will need to assess current and future curtailment risk > Curtailment assessments not necessarily to be provided by network operators May just direct customers to Long Term Development Statement (LTDS) > If provided (or commissioned by a 3rd party), some caveats may be required: Assessment only indicative as based on historic half-hourly information Assessment based on the current state of the network, and may not take account for changes to network topology or new connections DNO not responsible for the accuracy of the curtailment assessment, or the results of any actions the customer take on the basis of that assessment 18 The Voice of the Networks

19 Enabling faster & cheaper connections: ANM connection process 1. Information available on network operator website (capacity heat maps, ANM zones, curtailment design, etc.) 6.

20 Enabling faster & cheaper connections: Management of Costs Sole-User Costs > Scheme-specific costs: these may arise solely as a result of a particular ANM scheme (e.g. on-site ANM equipment) or, whilst not being attributable to one scheme, escalate as more schemes are added (e.g. upscaling central ANM equipment, or expanding the customer services team) Cost Apportioned > One-time costs: Some costs need to be incurred upfront, but do not change regardless of the number of ANM schemes enacted (e.g. upgrading the control room, and changing operational processes) 20 The Voice of the Networks

Network operator produces ANM connection offer with supporting information 9. Immediate notification and ongoing management of customer relationship 21 The Voice of the Networks

22 Enabling faster & cheaper connections: Longevity of ANM > Is ANM intended to be a temporary or enduring solution? Are there planned reinforcement schemes in progress? Any future changes to connected demand in the area? What is the cost recovery method? > Is there a need for a volume-based connection limit? Is there a finite amount of capacity released by ANM or; Should customers decide how much curtailment they can withstand? How will existing connections be affected by future connections? > Does the limit trigger reinforcement, and how are costs recovered? 22 The Voice of the Networks

24 ANM connection process ANM connection design Good practice: ANM connections > Principles of access can either be on a Last-In-First-Out (LIFO) or Pro-rata basis: LIFO may be preferred in situations where early projects are looking for certainty and simplicity Pro-rata may be preferred where maximising connections is an objective and applications are reasonably concurrent > If adopting Pro-rata approach a quota should be defined > If ANM is intended to be a temporary solution, the costs of reinforcement should be included in the connection agreement, especially under LIFO where customers will be exposed to different levels of curtailment > Guides and tools would ideally be made publicly available in a simple and clear format to help customers understand ANM connections > ANM connection offers should follow conventional offers, but network operators may notify a customer that they are eligible upfront > Information about the current and future network could be included in the connection offer as appropriate, with individual assets anonymised as necessary > Once connected, network operators may give notification of curtailment, periods when the scheme is active, and any changes to the scheme as necessary > Network operators should make clear to customers that they should carry out their own due diligence on the risk of curtailment, taking into account information provided by the network operator, but recognising the impact of unforeseen events (e.g. changes to network demand, technical failures, severe weather) 24 The Voice of the Networks

27 Using existing customers to maximise network utilisation: Possible actions 27 The Voice of the Networks

28 Using existing customers: Identifying candidate sites Implement conventional DSR? Upgrade to ANMenhanced DSR? > Is a reinforcement planned at a given network location? > Is DSR a viable option? Are enough of the right customers available to provide DSR? Would peak reduction actually allow reinforcement deferral in practice? > Is DSR a cost-effective solution when compared with the conventional alternatives, such as reinforcement and temporary generation? > Can the required customers be recruited successfully? > Is the network zone ANM-enabled already? How much would it cost to make the zone ANM-enabled? > How much more reinforcement deferral does ANM allow? > Is the increased deferral worth the additional cost of using ANM? 28 The Voice of the Networks

29 Using existing customers: Shortlisting candidates About the constraint About the customers > Date of planned reinforcements > Interactions with other planned reinforcement schemes > Cost of the planned reinforcement > Shape of the profile driving the constraint (e.g. flat vs peaky) > Rate of growth of net generation/demand before and after the planned reinforcement > Number and sizes of customers By geographical location (e.g. postcode) By topological location (i.e. ability to alleviate constraint) > Information about customer type (e.g. demand, storage or generator, response times, whether true DSR or behind-the-meter generation) > Whether the network is ANM-enabled > Estimate of generation/demand change under DSR, and a model of how customers would respond individually, and viewed as a portfolio 29 The Voice of the Networks

30 Using existing customers: Decision process 1. Identify planned reinforcement suitable for DSR 6. Monitor the constraint and call on DSR as required 7. Monitor the actual response received to ensure that it is in line with models 2. Assess technical viability of Conventional DSR and ANM-enhanced DSR 5. Update planning forecast to reflect the revised demand forecasts 3. Carry out Cost Benefit Analysis for each option 4. Recruit assets to provide the DSR solution 30 The Voice of the Networks

31 Using existing customers: CBA > Value of reinforcement deferral offset against DSR costs > Cost Benefit Analysis needed in each case Consider both capex and opex > Maximise Net Present Value (NPV) > Ensure no other constraints (e.g. technical or regulatory) Value of reinforcement deferral Net Present = - Additional value of Value (NPV) ANM-enhanced DSR Additional real option value of DSR Cost of operating DSR scheme Additional cost of ANMenhanced DSR 31 The Voice of the Networks

32 Using existing customers: Using 3 rd parties Increasing aggregator involvement Aggregators help identify and recruit potential DSR providers Aggregators could manage the ongoing relationship May be more efficient with the DSR providers DNOs could use the full and less costly than the DNOs doing this DNO would still choose aggregation service themselves which DSR customers to call upon Particularly if no inhouse function or skill set in place to perform this role. DNOs responsible for ensuring sufficient response to mitigate the constraint Aggregators enact the required DSR on behalf of the DNO From DNO s perspective, aggregator itself is the DSR provider 32 The Voice of the Networks

33 Using existing customers: restoring customers following a fault > Customer curtailment not necessarily on pre-fault basis Alternative is to manage customer reconnection following a fault using ANM > Managed reconnection Under conventional connection, customer supply usually restored within 1hr Using ANM a customer s essential supply can restored as soon as possible Restoration of non-essential power delayed for a pre-arranged period of time > Approach requires technical innovation and new commercial contracts Increased network capacity Technical innovation Commercial contracts Utilised capacity Current demand Latent capacity 33 The Voice of the Networks

34 Using existing customers: Traditional network design > Diagram below shows Normally Open Point (NOP) between two adjacent radial high voltage (HV) circuits > This network configuration can be enhanced with ANM Normal open point 34 The Voice of the Networks

35 Using existing customers: Network design for post-fault restoration > Remote control installed at the NOP Closed to form a closed ring and so increase available latent capacity > Additional remote controls installed Enable flexible rapid re-supply of customers following an outage. Decreases amount of time non-managed customers are off supply due to a fault Remote automation Automated restoration software Mid-point closed 35 The Voice of the Networks

36 Using existing customers: restoring customers (commercials) > DNOs and their wider customers benefit financially from this approach DNOs therefore willing to pay for the service through commercial DSR agreements Customers would be financially incentivised to accept managed restoration incentive > Approach can be used for both new and existing customers Existing customers would receive a fee Newly-connecting customers may be offered lower connection charges DSR financial incentive More of the network capacity to be utilised Reduced need for reinforcement 36 The Voice of the Networks

37 Using existing customers: restoring customers (customer engagement) > To date, trials have seen more rapid take-up by existing customers Uncertainty regarding disruption or multiple disruptions Existing customers have DNO relationship and understand fault frequency > Highlights the need to reassure potential DSR providers Impact on consumers minimised by: Taking action only following a fault Prioritising essential power in the restoration process Allowing customers control over DSR commercial terms, e.g. Maximum outages per annum and duration Flexible protected periods 37 The Voice of the Networks

38 Deferring general Good practice: Deferring general reinforcement reinforcement > A network operator s Planning team should be able to carry out a quick assessment of planned reinforcements to assess their possible suitability for deferral using DSR, perhaps with a unified database or a tool > There should be regular communication between the Planning, Connections and, where required, a dedicated DSR function to identify and assess plausible candidate DSR sites (if not provided by a 3rd party) > A technical feasibility assessment should be carried out, taking into consideration the nature of the constraint, the number and types of asset behind that constraint, the DSR each might be able to deliver and the contribution that this could make to security of supply > An appropriate economic case should be made each time DSR is considered > Some form of regular audit may be required to ensure that the achieved DSR is delivering the expected response at the intended cost, and that the business case for DSR remains valid > ANM can also be used following a fault to manage the restoration of customer supply, allowing more of the latent network capacity to be used with minimal impact on consumers 38 The Voice of the Networks

41 Deploying ANM technical Technical Architecture > Types > Features > Benefits Functional Specifications > Main categories > Implications 41 The Voice of the Networks

42 Deploying ANM (technical): System Architecture - Decentralised 42 The Voice of the Networks

43 Deploying ANM (technical): System Architecture - Centralised 43 The Voice of the Networks

44 Deploying ANM (technical): System architecture key features (1) Decentralised Centralised Scheme location Constraint type Service provided Controllability & Visibility Low strength of communications links to centralised location More suitable for localised constraints Can provide faster service that SCADA and NMS. Lower visibility and controllability if communications with central network control not so reliable and/or robust Strong existing SCADA and no locational issues with hardware deployment Management of a wider grid constraints Consistent with response timings provided by the SCADA system and NMS. Good visibility and controllability of the scheme. 44 The Voice of the Networks

45 Deploying ANM (technical): System architecture key features (2) Decentralised Centralised Reliability Cost More components, more chance of failure though reduced chance of catastrophic failure Greater number of hardware devices Dual SCADA communications structure provides redundancy, NMS is a single point of failure Costs to fully integrate within the NMS (or stand-alone equivalent) Security Easily segregated from NMS so connection of customer assets and control systems should not affect NMS security Security challenge due to integration of customer assets and control systems into the NMS 45 The Voice of the Networks

46 Deploying ANM (technical): Functional specification > DNO provide functional specifications to which an ANM scheme must adhere Includes key features to allow the ANM scheme to integrate with the existing systems > Functional specifications set out by DNOs fall into the following four main categories 46 The Voice of the Networks

47 Deploying ANM (technical): Functional specification System Configuration and Algorithms > Real-time analysis of network parameters in relation to limits > Capability to perform control and parameter management actions > Implement principles of access > Ability to adapt to changes in system conditions > Detect and take action in instances of nonresponse or non-compliance > Apply failsafe methods > Performance Criteria Measurements and Data Exchange > Data Resolution and Polling > Data Processing > Interfacing Capabilities > Data Exchange with the Control Room Communicating and Interfacing > Communication Links > Communication Protocols > Redundancy > Third Party Communications > Physical & Cyber Security > Performance Criteria Forecasting > Forecasting functionality not typically incorporated into UKdeployed ANM > One exception of SSEPD s NINES project on Shetland 47 The Voice of the Networks

48 Deploying ANM (technical): Control room visibility and failsafe > Essential that the DNO control room has visibility of ANM schemes > Control engineers are provided with the two main methods of interaction with ANM 48 The Voice of the Networks

49 Deploying ANM (technical): Failsafe ANM Failsafe Modes Technical nonresponse of ANM customer Loss of local/anm communications Loss of central/network communications Loss of ANM scheme or individual components 49 The Voice of the Networks

50 System Functional Good Practice: Deploying ANM (technical) 1 architecture Specifications > A centralised architecture is preferred to manage wider network constraints > A decentralised architecture is favoured where rapid response timescales are required > A hybrid approach can improve overall ANM scheme reliability by having improved communications redundancy over decentralised architectures and removing the single point of failure feature characteristic of centralised architectures > Where existing communications assets are to be used, the network SCADA measurement and polling rates should be assessed for their suitability to support the ANM scheme performance requirements. Alternatively, modifications could be made, or new assets may be required > The latency and reliability of ANM operation should be assessed to ensure this will not adversely affect scheme efficacy. Curtailment thresholds may include a buffer to account for the latency of the ANM system. > DNOs should specify what existing systems and protocols the ANM scheme must be capable of interfacing with > There should be adequate communications redundancy as appropriate for the application > Consideration of security issues and network protection are needed prior to deployment 50 The Voice of the Networks

51 Control room ANM failsafe modes Good Practice: Deploying ANM (technical) 2 > Control engineer responsibility should be agreed in the early stages of the integration process to ensure the correct SCADA notifications and controls are provided > A Human Machine Interface (HMI) dashboard should be provided within the Network Management System with ANM scheme overview > Controls should be made accessible from within the HMI > Adequate training and familiarisation should be provided to control engineers on ANM scheme operation and accompanying HMI > Failsafe modes must be integral to an ANM scheme algorithm > Non-responsive generation is disconnected or constrained to failsafe level > Generation is disconnected or constrained to failsafe level upon loss of communication unless back-up communications are available > Generation is disconnected or constrained to failsafe level upon loss or disabling of the ANM scheme > Failsafe level of generation is 0 MW but this could change in future owing to local considerations and constraints 51 The Voice of the Networks

52 Deploying ANM (People & process): People & process > Transition to business as usual > Skills requirements > Stakeholders and changing responsibilities > Training > Good practice summary 52 The Voice of the Networks

53 Deploying ANM (People & process): Moving to business as usual Innovation / R&D team > Individual trials of ANM > Relatively small team > Multi-disciplinary expertise > Ad-hoc use of existing business functions Business as usual > Choice of operating model function specific team or use staff in existing roles > Develop procedures and processes > Responsibilities > Training 53 The Voice of the Networks

54 Deploying ANM (People & process): Skills requirements ICT support Project management Power system planning Power system design Active vendor interaction Active management in control room Active customer management Training and field advice Quotations Field support Novel commercial contracts Extreme specialisms Change management 54 The Voice of the Networks

55 Deploying ANM (People & process): Stakeholders and responsibilities Connections > Undertake curtailment assessments and provide connection offers Network planning Network design > > Determine available capacity / connections pipeline, identify DSR candidates Assess the network impact of ANM connections Field teams > Installation, maintenance and repair ICT > Determine existing system capabilities and upgrade as necessary Deal with queries from ANM customers Contact centres > Control room > Adapt to ANM action, outage planning and ANM intervention 55 The Voice of the Networks

56 Deploying ANM (People & process): Training Modelling tools Fault resolution Commercial arrangements Network / systems interaction Customer service Formal training, ongoing support, manuals, user guides, tools Technical details Curtailment assessments Record keeping Cost benefit analysis Scheme design 56 The Voice of the Networks

57 Good Practice: Deploying ANM (people & process) People and Processes > ANM affects multiple stakeholders within a network business, each of whom would ideally be brought on board early in the implementation to smooth the transition > Suitable business owners in each department should be identified to coordinate the ANM scheme > A central ANM team will help with coordination efforts, but does not need to be a large function until the ANM scheme is more fully implemented > Effective training will be important, and may take the form of formal training, ongoing support, manuals, user guides or tools > Training will need to cover a wide range of subjects including technical proficiency, commercial negotiations and data management 57 The Voice of the Networks

77 Future developments: Technology > Technology is continually evolving and this will impact the design and implementation of future ANM schemes From a DNO perspective Communications are commonly considered to be the single biggest technology challenge for ANM deployment at distribution level (and future networks as a whole) From a TSO perspective The major challenge of ANM will come from controllability and the need for a well-defined control hierarchy > Key technical considerations that will influence how ANM evolves: Communications and convergence on a common standard ANM technology embedded in DNO field devices 77 The Voice of the Networks

78 Future developments: Network operation practices The increasing number of flexible connection contracts offered to distributed generation and demand through ANM schemes, challenges the traditional notion of security of supply Current and any future revisions of Engineering Recommendation P2/6 should take this into account and anticipate future developments such that the standard remains valid in the coming years A possible widening of statutory steady state voltage limits in future could enable more generation to connect, potentially leading to increased thermal constraints in future Statutory steady-state voltage limits in GB are being examined in a number of research projects with a view to extending the allowable voltage bandwidth for operation, where there is an acceptable techno-economic case 78 The Voice of the Networks

79 Future developments: ANM applications > The current role for ANM is expected to be managing thermal constraints in order to keep the network within its pre-fault (intact) limits > As the technology becomes more responsive and develops a proven track record of reliable operation, it may be able to use ANM in new ways Zonal voltage and reactive power management Post-fault operation Fault level management Monitoring and controlling voltage and reactive power on the network, with the ANM system triggering different actions depending on which constraint is binding at a particular time Using ANM in real-time, as an instantaneous reaction to a fault, with no loss of service. ANM equipment would have to be of the same standard as protection equipment in terms of reaction time and reliability When back-up generators synchronise with the grid, non-firm generators could be disconnected to keep the system within fault level limits. 79 The Voice of the Networks

80 Future developments: DSO role ANM + other smart technologies Smart Grid DSO role Actively managing the network using a range of operational tool and services Primary benefit is that distribution networks can be managed more efficiently Indirectly or directly controlling connected customers (generation, demand and storage) Can also broaden the asset base from which the TSO can procure balancing services Potentially involves making payments for the actions taken Potentially profound changes to interactions between T&D networks, electricity balancing as a whole 80 The Voice of the Networks
