ENHANCING SOCIAL WELFARE IN ELECTRICITY MARKET WITH TCSC DEVICE USING CUCKOO OPTIMAZATION ALGORITHM

Abstract

The creating electricity market has brought much social welfare. However, it also causes the system to frequently congestion. Congestion has a direct impact on trading contracts and reduces social welfare. Therefore, in order to eliminate congestion, maximum social welfare, need to build new transmission lines. This is often difficult from regulating state and environmental policies. Thus, rebalancing power flow by using TCSC to improve its transfer capability and maximization social welfare is on of important problems for operator system. In order to solve this problem, many algorithms metaheuristic have been proposed in previous reseach. However, the application of Cuckoo Optimazation Algorithm (COA) to solve this problem hasn’t been proposed by the research groups before. Thus, in this paper, COA has proposed and applicated to solve the OPF problem for maximization the social welfare via optimal installation of TCSC devices. The method proposed is tested with IEEE 14 bus test systems. Result simulations are compared with GA and GWO show that the COA also is one of the useful methods for TCSC installation to maximum social welfare.
