Dynamic economic dispatch with valve point effect, prohibited operation zones, and multiple fuel option

Abstract

In this paper a mixed integer quadratic programming (MIQP) is proposed to solve the dynamic economic dispatch (DED) with valve-point effect (VPE), prohibited operation zones (POZs), and multiple fuel option (MFO). The non-convex, non-continuous cost functions caused by VPE, POZs, and MFO are piecewise linearized and solved by a MIQP. The effects of VPE, POZs, and MFO on the computation efficiency are analyzed. It shown that the VPE has much larger impact on the computation efficiency than POZs and MFO. The proposed method is tested on a 10-unit system.
