Dynamic Economic Dispatch Using Hybrid DE-SQP for Generating Units with Valve-Point Effects

Dynamic Economic Dispatch Using Hybrid DE-SQP for Generating Units with Valve-Point Effects

This paper presents hybrid differential evolution (DE) and sequential quadratic programming (SQP) for solving the dynamic economic dispatch (DED) problem for generating units with valve-point effects. DE is used as a global optimizer and SQP is used as a fine tuning to determine the optimal solution...
