“…With the rapid developments in power electronic devices, FACTS devices have become more attractive for long distance power transmission. Recently, FACTS devices have gained more popularity in power system operations for their contributions in modifying the control parameters to achieve a satisfactory power handling capability [4]- [7]. The Unified Power Flow Controller (UPFC) is one such device considered for regulating the real and reactive power flow independently with adaptive control strategy.…”

-This paper presents the improvement of the voltage profiles of power system networks by the inclusion of Unified Power Flow Controller (UPFC). The mathematical model of the UPFC is incorporated in the load flow algorithm and the L-index is calculated for the different values of the control parameter r andγ. The positioning of the UPFC device is changed to minimize the sum of the squares of the L-indices at all load buses. The test cases considered for the improvement of voltage profile with the WSCC 9-bus and IEEE 30 bus system. With the best position of UPFC along with the control parameters the improvement in voltage profile of the power system networks are obtained. The results obtained are quite encouraging compared with other techniques used to identify the best location of UPFC.

“…There are different modes of operation for each of the inverters constituting the UPFC [11]- [13]. In this paper, the following constraints to the modes of operation are considered when designing the UPFC control system: • For the series compensation inverter, the phase and magnitude of the inserted compensation voltage are controlled so as to maintain or vary the active and reactive power-flow in the transmission line within a predetermined region: this is known as automatic power-flow mode of operation.…”

“…The need for series compensation is valuable and of more interest in deregulated power markets to improve the overall utilization of an electrical power network. The many qualifications of series compensation technology enrich the flexibility of the existing power networks [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23].…”

Multicriteria Selection of Optimal Location of TCSC in a Competitive Energy Market

The paper investigates selection of the best location of thyristor-controlled series compensator (TCSC) in a transmission system from many candidate locations in a competitive energy market such that the TCSC causes a net valuable impact on congestion management outcome, transmission utilization, transmission losses, voltage stability, degree of fulfillment of spot market contracts, and system security. The problem is treated as a multicriteria decision-making process such that the candidate locations of TCSC are the alternatives and the conflicting objectives are the outcomes of the dispatch process, which may have different importance weights. The paper proposes some performance indices that the dispatch decisionmaking entity can use to measure market dispatch outcomes of each alternative. Based on agreed-upon preferences, the measures presented may help the decision maker compare and rank dispatch scenarios to ultimately decide which location is the optimal one. To solve the multicriteria decision, we use the preference ranking organization method for enrichment evaluations (PROMETHEE), which is a multicriteria decision support method that can handle complex conflicting-objective decision-making processes.K e y w o r d s:
