Solving Optimal Unit Commitment Problem Based on Wind Power Effects Using Harmony Search Algorithm

In this paper, Multi Objective Harmony Search Algorithm (MOHSA) is used to solve the Unit Commitment (UC) problem between thermal generating units with wind impact an electricity market to minimize total cost to achieve a real system considered with various generator and wind constraints in power systems. Today the wind power is utilized as energy in power systems to play an important role in remedying the many shortcomings in today’s modern energy electricity market. Actually, wind power becomes a far bigger issue when its total contribution in the renewable power system increases. The effectiveness of the proposed technique is applied to 10 thermal and wind units with various conditions. The achieved numerical results demonstrate the superiority of the proposed technique in comparison with SPSO, GA and λ-iteration to understand the wind generator capacity in production cost analysis and to provide valuable information for both operational and planning problems.
