Hybrid Differential Evolution for Power Economic Dispatch Problems Considering the Incorporated Cost Model

This paper presents an effective algorithm to solve power economic dispatch (PED) problems considering incorporated cost model of valve-point effects and multiple fuels. The proposed algorithm integrates the hybrid differential evolution (HDE) and the multiplier updating (MU). Few PED problems related studies have seldom addressed both valve-point loadings and change fuels. To show the advantages of the proposed algorithm, was employed to test PED problems with one test system considering the incorporated cost model. Additionally, the proposed algorithm was compared with the differential evolution (DE), revealing that the proposed method is more effective and efficient than the DE in application of power system.
