Hybrid algorithm for dynamic economic dispatch with valve‐point effects.

Dynamic economic dispatch problem in power system considering valve‐point effects of generators is a non‐smooth, non‐convex and multi‐dimensional constrained optimisation problem. In allusion to those characteristics, this study proposes a hybrid algorithm which integrates low‐discrepancy sequences, improved shuffled frog leaping algorithm and sequential quadratic programming. The effectiveness of the proposed method has been verified by using case studies based on 5‐unit, 10‐unit and 30‐unit test systems over a period of 24 h. The results show that the proposed method has improved solution quality and computation efficiency, compared with most current approaches. [ABSTRACT FROM AUTHOR]
