WIND POWER EFFECT OVER UNIT COMMITMENT GENERATING VIA GRAVITATIONAL SEARCH ALGORITHM

In this paper, Gravitational Search Algorithm (GSA) is proposed to solve the Unit Commitment (UC) problem between thermal generating units with wind impact anelectricity market to minimize total cost. Actually, the wind energy is one of the renewable energies which can be used inpower systems. This issue is used in this paperto achieved a real system considered with various generator and wind constraints in power systems. To demonstrate theeffectiveness and robustness of the proposed algorithm a system with ten thermal and wind units with various condition is simulated. Theresults and numerical experiments are compared with PSO, GA and λ-iteration to understand the wind generator capacity inproduction cost analysis and to provide valuable information for both operational and planning problems.
