Proposed Differential Evolution Technique for Solving the Power System Economic Load Dispatch Problem

Sapna Kapoor, Rameshwar Singh

Electrical power industry restructuring has created highly vibrant and competitive market that altered many aspects of the power industry. In this changed scenario, scarcity of energy resources, increasing power generation cost, environment concern, ever growing demand for electrical energy necessitate optimal economic dispatch. In This paper presents an application of the Differential Evolution optimization algorithm to power system economic load dispatch problem with ramp rate limit for 15 unit test case system. Power system Economic load dispatch problems are applied and compared its solution quality and computation efficiency to Genetic algorithm (GA) and Differential Evolution optimization algorithm.
