Optimal placement of STATCOM for voltage control using partitioning methods and fuzzy adaptive modified particle swarm optimization algorithm

In this paper, a fuzzy method called C-Means is used for division of a power system into different region. The extension of disturbance between these regions can be avoided by using a FACTS-embedded local controller in each region. Optimal location of FACTS devices (STATCOM) are determined by designing a voltage control method and using an optimization algorithm. This control method is a decentralized approach that prevents unallowable deviation of voltage during disturbances. To verify the performance of the proposed method, 118-bus IEEE power system is used. The simulation results show the desirable performance of the proposed method.
