Enhancement of Available Transfer Capability using Particle Swarm Optimization technique with Interline Power flow Controller

Deregulation of the electricity industry throughout the world aims at creating a competitive market to trade electricity, which generates a host of new technical challenges to market participants and power system researchers. The benefits of deregulate market are cheaper electricity, efficient capacity expansion planning, cost minimization, more choice and better services. For better transmission services support and full utilization of transmission assets, one of the major challenges is to accurately gauge the transfer capability remaining in the system for further transactions, which is termed Available Transfer Capability (ATC). It is crucial to develop an appropriate ATC determination methodology that enables one to evaluate the realistic transmission transfer capability by accounting for all related important requirements. The insertion of FACTS devices in electrical systems seems to be a promising strategy to enhance ATC. In this thesis, the ATC is calculated using AC Power Transfer Distribution Factors (ACPTDF) method. Then the calculated ATC is enhanced by incorporating Interline Power Flow Controller (IPFC).Real Coded Particle Swarm Optimization technique (PSO) is employed to obtain the optimal settings of IPFC. The work has been carried out on IEEE 30 bus systems in MATLAB 7.10.0 for bilateral transaction and the results obtained are quite encouraging.
