Power market design US vs EU Abstract of the project The two largest market areas for electricity are in the US and the EU respectively. Both are liberalized markets in contrast to a state owned, monopoly driven electricity supply system. However, there are still great differences between seperate market areas within those two regions and even greater between the US and the EU. An example is the locational pricing in the PJM which is opposed to the approach of a uniform market price for the whole German market area. Tasks The student will study the market design of the european electricity market mostly by reading reports and papers. He will create an active discussion about the differences in market design within the EU and compared to the US by preparing a discussion on a regularly basis (e.g. weekly). The student will develop a framework in order to identify important differences in market design in a easy-to-comprehend way. Requirements A deep understanding of energy economics is imperative. Knowledge about electricity markets and different designs (e.g. nodal pricing, zonal pricing, congestion management) will prove very helpful. Most important is a desire to learn more about electricity market designs and the ability to communicate open questions and results.

Local power generation and electricity storages Abstract of the project The design of a likewise sustainable, climatefriendly, safe, and efficient energy supply presents both current and future society with great challenges. In order to meet this requirement, the energy sector, driven by political, economic, and social decisions, is changing continuously. This evolution thereby affects all areas of energy supply, namely provision, transport, distribution and demand. Induced by expansion of decentralized electricity generation by renewable energy sources (RES), use of storage, new load characteristics such as electric vehicles (EVs), and market liberalization as well as increased involvement of society on climate protection and market participation, the growing number and heterogeneity of actors and elements particularly increase the complexity of the electricity sector. To estimate the potential of new designs of a future power supply system, its elements and their impact on the system must be analyzed in detail. Therefore individual consumers and their cost optimized scheduling of power consumption (incl. charging of the EV), generation, and especially storage have to be examined in detail. The consumers individual optimization problems are modeled as mixed-integer linear program for typical days over a changing time horizon. A focus is set on consumers with stationary storages. The optimization of the consumers is iterated at each time step of an agent based model to be able to simulate learning ef-fects and reactivity. Additionally, uncertainties are considered by the configuration of the structure (e.g., lack of information) and environment (e.g. weather, affecting sunshine hours), as well as by introducing bounded rationality of the consumers. Tasks Requirements During this internship first, a detailed overview on the use, operation and state of the art of stationary storages within decentralized energy systems should be provided. In the following the individual optimization problem of a consumer with a stationary storage is to be developed and adjusted to the technical constraints of the storages. This step is performed using mathematical programs which require certain programming abilities. Finally, the modeled consumer can be included into an agent based model which is programmed in a Java environment. After a parametrization of the consumer its impact on the grid can be studied in detail. programming abilities (e.g. Java)

DEMO (DEMOnstration Power Plant) mechanical pipe connections (R&D) Abstract of the project DEMO (DEMOnstration Power Plant) is a concept nuclear fusion power plant. The project builds upon on the knowledge gained from ITER experimental nuclear fusion reactor which is being constructed in southern France. The goal of the project is to pave the way for the first commercial nuclear fusion power plant. DEMO is a vast project which offers a large amount of different tasks and opportunities to get involved. In this case the student will be able to take part in the design of the cooling and purge pipes of the nuclear fusion reactor. More specifically, the goal is to develop a mechanical pipe connection system which allows for a quick assembly/disassembly of single/multiple pipes and fits specific boundary conditions, such as remote handling capability. The student will have the opportunity to develop their own ideas as well as to research commercially available solutions on the market which could be possibly adapted for the current goal. The Institute of Material Handling and Logistics offers a friendly, creative working environment, very suitable for a young engineering student to hone their skills and gain additional knowledge and experience in their field of study. Tasks Requirements Language Skills Software Skills The main tasks to be performed by the trainee include: - Perform a market research for commercially available multiple pipe connection systems. - Assess systems for their remote handling capability - Develop new mechanical connection concepts - Implement said concepts in CAD models - Perform RH tooling research/design Candidates have to be interested in mechanical design and show high affinity for designing new components. A student majoring in mechanical engineering or design and manufacturing would be a perfect fit for this internship. All applicants are expected to have experience with MS Office and CAD software (where experience with CATIA or ProEngineer is an advantage.)

Flow boiling of CO2 in metal foams Abstract of the project Improving the ecological and economical performance of vapor-compression refrigeration systems is essential to reduce the lifecycle greenhouse gas emissions attributed to such a system. Thus, the heat transfer and the pressure drop during flow boiling in the evaporator tubes should be optimized. Such an enhancement could be obtained by integrating metal sponges into the evaporator tubes. Metal sponges are cellular structures with two continuous phases. Owing to their high porosity, metal sponges combine a large internal surface area, a high density of nucleation sites, and a continuous renewal of the thermal boundary layer while providing a moderate pressure drop. Only some experimental and numerical investigations on flow boiling in horizontal tubes filled with metal sponges are published. The results of these investigations are partially contradictory because of the demanding measurement technology and the complex underlying phenomena. Consequently, a test section which allows assessing the enhancement of flow boiling by metal foams is being planned in our institute. Special care is taken to measure the temperature field. Moreover, the results of the test section can be compared to measurements with a smooth and an enhanced tube obtained by the same test rig. The same thermal and geometrical boundary conditions are chosen to ensure comparability. Additionally, the influence of the contact between tube and metal foam can be evaluated. Tasks Requirements Language Skills Software Skills The student will be involved in the project. Her/his specific task will be altering an existing LabVIEW routine to obtain and simultaneously assess measurement data. LabVIEW is a data acquisition programming environment.
