机组组合问题的两层优化研究

Abstract

Abstract:

A bi-level decision-making method for the network-constrained unit commitment (UC) problem was proposed. The upper level with the objective to minimize the total cost of subsystems solves the optimal power flow problems including network constraints and determines the generations of subsystems in the lower level. A subsystem is composed of generators in one system without network constraints and minimizes its generation cost to give the units states. The two levels are solved alternatively according to the marginal information of the lower level. Two study cases were analyzed to exhibit the effectiveness of the method presented.

Key words: power system, unit commitment, network constraints, bi-level programming
