Solving Dynamic Economic Dispatch With Modified PSO Algorithm Considering Valve Point Effects And Ramp Rate Limits

Abstract

The practical dynamic economic dispatch (DED), with consideration of valve-point effects, and ramp up, ramp down generators constraints considered as a complicated non-linear constrained optimization problem. In this paper, a new variant swarm optimization based time varying acceleration (PSO-TVAC) proposed to solve this problem. This algorithm has been compared and found to be superior compared to the results of classical (PSO) and (GA) method in term of solution quality and convergence characteristic
