A Modified Imperialist Competitive Algorithm for Solving Profit Based Unit Commitment Problem abstract
Deregulation of electric power market has changed traditional infrastructures of generation, transmission and distribution, drastically. In case of power generation, theclassical unit commitment that has been aimed to minimize operation costs, once; should be implemented by Generationcompanies (GENCOs) aiming at maximizing their own profit,now. In a novel price-based unit commitment (PBUC), constraint related to supplying the forecasted electricity demand is relaxed; while, it was a hard constraint in a costbased unit commitment. In a restructured power market,system operators can utilize the PBUC to develop a successfulbidding for participant generators. In such an environment, the signal that would enforce a unit to be in ON or OFF status would be the energy price, including the fuel purchase price and the energy sale. In this paper, a hybrid Imperialistic Competitive Algorithm (ICA) – Diversity Guided Evolutionary Algorithm (DGEA) approach is proposed to implement the PBUC problem. The proposed method is capable of aiding GENCOs to provide an optimal scheduling in order to sell some adequate amount of energy in the power market andsubsequently, to reach maximum profit. The effectiveness of presented approach to overcome the complexity of non-convex optimization problem of PBUC is validated using a test system available in the literature.
