Solving Non-convex Economic Dispatch with Valve Point Loading Effect using Imperialist Competitive Algorithm

Generation of electrical energy in order to minimizing cost is one of the main issues in modern power networks. Economic dispatch is the most proper solution which leads to an optimal and effective programming for generative units which takes the utility grid’s constraints and factors into account. The present study investigates the economic load dispatch problem, using an imperialist competitive algorithm while considering valve point loading effect. To portray the efficiency of the proposed method, the algorithm is applied to two popular test systems in the area including 13 and 40 thermal units. The obtained results are compared to those of other algorithms which indicates the efficiency and priority of the proposed algorithm in solving economic load dispatch problem.
