Immune-PSO for Economic Dispatch with Valve Point Effect

Abstract:

This paper presents a simple and efficient approach for solving the nonconvex economic dispatch (ED) problems based on Immune-pso algorithm. ED is one of the most important problems in power system operation and planning. The aim of the ED problem is to determine the optimal combination of power outputs of all generating units so as to meet the required load demand at minimum operating cost while satisfying system equality and inequality constraints. This paper proposes an novel Immune-PSO algorithm to handle the equality and inequality constraints in ED problems. The Immune-PSO can be used as an optimizer providing the global solution while satisfying constraints for the nonconvex ED problems. To verify the feasibility of the proposed method, numerical studies have been performed for test systems.
