Apart from tradtonal power flow controllng devces, use of Flexble AC Transmsson System (FACTS) devces can gve an attractve soluton for the operaton and control of deregulated power system. The type, sze, locaton and number of FACTS devces are to be optmzed approprately n order to get the targeted benefts. In ths paper, two FACTS devces, and IPFC are selected to obtan the requred performance. To search the optmal locaton and optmal ratng of the selected FACTS devces, a hybrd algorthm whch formulated wth PSO and GSA s proposed. At the frst step, the optmzaton problem s solved for fndng the optmal locaton of FACTS devces usng PSO wth an objectve of voltage profle mzaton and later GSA s mplemented to optmze ther parameters wth an objectve of transmsson loss mnmzaton. The proposed method s mplemented on IEEE 30-bus test system and from the smulaton results t can be proved that ths technque s well suted for real-tme applcaton. Keywords: Deregulated power system, open access,, IPFC, PSO-GSA I. Introducton The practcal lmtatons to expanson and ever ncreasng electrcty demand are causng to operate transmsson system at ts bottleneck under compettve envronment n deregulated power system. In addton, the randomness n power njecton and wthdrawals wth the strategc behavor of market partcpants are further causng to decrease the securty margn of transmsson system. Under ths scenaro, the prmary objectves to ntroduce Flexble AC Transmsson System (FACTS) devces are redefned by many researchers durng last decade. Some of the major areas focused wth FACTS devces are lke securty margn enhancement [-3], stablty enhancement [4-0], relablty management [], system performance mprovement [2-9], congeston management [20-24] and electrcty market economc effcency mzaton [25-30] etc. As per the controllng attrbute n power system, the type, sze, locaton, number etc. are requred to optmze very precsely. Many researchers have attempted to solve ths problem by heurstc algorthms due to ther adoptablty for mult-objectve complex problems. Usng Genetc Algorthm (GA), the optmal locaton and number of thyrstor-controlled phase shfters are optmzed n [3, 32]. In [33], hybrd TS/SA approach has been proposed to solve OPF problem ncorporatng FACTS devces. An evolutonary algorthm based evoluton strateges (ES) technque s proposed to mze system loadablty va optmzng type of FACTS devce, ther locaton and settngs [34]. Smlarly, the ABC algorthm and PSO algorthm applcaton for optmzng IPFC locaton can be found [35, 36]. On other sde, the conventonal approach lke mxed-nteger nonlnear programmng (MINLP) s adopted to fnd the optmal settng of FACTS devces used n the optmal power-flow problem. [37].It s worthwhle to notfy the role of heurstc algorthms used to solve n all these complex problems. The objectve of ths paper s not only to resolve mult-objectve optmzaton problem but also to nvestgate the effectveness wth the use of FACTS devces for the mprovement of the performance of transmsson system. Ths s an extenson of our exstng works [38] under open access envronment. Under open access, the blateral or multlateral transactons are executed wth an assumpton of unconstraned transmsson system. Wth ths new generaton and loadng levels, the ablty of varous FACTS devces for the mprovement of the transmsson system performance s analyzed. Two FACTS devces, and IPFC devces are used n ths work. To dentfy the most sutable locatons, the Partcle Swarm Optmzaton (PSO) s appled frst. Later, the Gravtatonal Search Algorthm (GSA) s mplemented to fnd the optmal parameters of the FACTS devces. The overall voltage devaton ndex () s consdered whle optmzng the locaton and the transmsson loss s consdered whle optmzng the parameters of FACTS devces. Ths paper s arranged as follows: secton gves ntroducton, secton 2 shows the power njecton modelng of varous FACTS devces. Secton 3 explans the objectve functon n the necessary mathematcal DOI: / Page

Secton 5 deals wth varous case studes on standard IEEE test systems and secton 6 concludes the paper. II. Modelng of FACTS Devces 2.. Thyrstor Controller Phase Shft Transformer As far as the statc modelng s concerned, the power njecton equatons are as follows: Pnj, r VV j sn j tcpst X se Q r V r VV cos 2 2 nj, j j tcpst Xse Xse P P nj, j nj, Q r VV cos nj, j j j tcpst X se where, tan tcpst s the phase angle adjustment by between, 2 2, r s the rato between the magntude of the nduced seres voltage and magntude of the th bus voltage. It s varable n the range 0, r, 2 and j are the load angles of buses, j respectvely. In addton, X se xse n xsh, where xse and xsh are the seres and shunt reactances of transmsson lne/transformer and n s the varable of the phase shft angle. The detaled nformaton can be found n [39] Interlne Power Flow Controller By assumng IPFC locaton between buses, j and k, the power njectons are as follows [5, 6]. Here V se n and se n P V V b sn nj, sen n sen n j, k Q V V b cos nj, sen n sen n j, k Pnj, n Vj Vse b sn n n j se n n j, k Qnj, n Vj Vse bn cosj se n j, k n are the magntude and angle of seres njected voltage source. III. Problem Formulaton The transmsson system performance can be mathematcally formulated n terms of two terms: voltage devaton of the system, f x, u, and transmsson losses, f2 x, u. Therefore the major objectve functon can be defned as: F x, u f x, u, f2x, u The frst objectve s to optmze the overall system voltage profle.e., mnmze the voltage devaton at load buses, whch can be defned as,, DOI: / Page NLB f x u x u V V ref where L s the number of load buses, V s the pre-specfed reference magntude at th load bus, whch usually wth magntude of.0 p.u. The second objectve s to mnmze the total real power loss of the lnes, whch s wrtten as:, loss, NL f x u P x u P n ref 2, loss where P, loss s the real power loss n transmsson lne, and NL s the total number of transmsson lnes. In both the objectve functons, x denotes the vector of dependent varables such as slack bus power P G, generator reactve power outputs Q G, load bus voltages V L and apparent power flows n transmsson lnes S L. Therefore x can be defned as: T x P, Q,... Q, V,... V, S,... S G G NGB L NLB L NL 2

Smlarly, u denotes the vector of control varables such as generator bus voltages V G, locaton of FACTS devces L, and real and reactve power njectons P nj & Q nj at FACTS devce ncdent buses, j respectvely. Therefore u can be expressed as: T u VG,... VNGB, L,...

The real load of the system s MW. We have allocated MW for generator 2 and the rest of load s allocated to generator. Snce the test system has consstng of 6 generator buses and 2 load buses. Hence each generator can treat as source bus and smlarly each load bus can be lke a snk bus n open access envronment. Snce the partcpants and ther requred MW quanttes are unpredctable n real-tme, we have determned by usng random numbers theory. It means, the algorthm wll decde the source bus and snk bus as well as ther contracted power. For each smulaton, we can have ether blateral or multlateral contracts and hence numerous case studes can generate. Here we have gven some lmted transactons. 5. Wth 5...

Loss n each transmsson lne wth IPFC VI. Concluson In open access transmsson system, the transactons can take place at any tme among varous market partcpants. Some transactons can cause to decrease total transmsson losses due to counter flows and some are cause to ncrease due to domnant flows. Irrespectve of transactons and ther volumes, the major responsblty of power system engneers s to decrease net transmsson losses as well as to mantan good voltage profle for the better performance of system. In ths paper, the mpact of and IPFC on system performance s analyzed for both blateral and multlateral transactons. It has been observed that the transmsson losses are decreased and voltage profle s ncreased sgnfcantly wth FACTS controllers n the network. The adopted hybrd algorthm GSA-PSO s proved ts ablty to solve complex optmzaton problem wth multple objectves. References [] Gerbex, S., R. Cherkaou, and A. J. Germond.
