Abstract— This paper involves a novel application of the improved particle swarm optimization (IPSO) in an economic dispatch problem (EDP) that consists influence of valve-point loading, power balance, and generators constraints. This method is able to improve the best value of the cost function with a slight increase in the average time trials. This procedure is suitable for solving large-scale and complex economic dispatch problems. In this report, IPSO algorithm is tested on three systems and experimental results are compared with other efficient methods. Simulation results demonstrate the efficiency of proposed algorithms for solving economic dispatching problems.

Introduction
The main object of EDPs for generating the electricity is to adjust the output of generator unit for minimizing the final cost of them to establish a balance between demand load and generator production. Beside this numerous cases, all equal and…
