Intelligent Controller Based Wide-Area Control in Power System

A new strategy based on Takagi-Sugeno fuzzy controller is proposed in this paper for wide-area power system. In this strategy, the proposed fuzzy controller is optimized by a new hybrid meta-heuristic algorithm and hyperplane clustering algorithm to partition the fuzzy space of the given input-output data. A global signal from the centralized controller is employed in wide area control (WAC) scheme to damp out the inter-area mode as well as local mode of oscillations. To demonstrate the capability of proposed strategy, three case studies have been used in this paper. The obtained results demonstrate the validity of proposed strategy through comparison with other techniques in this problem.
