摘要
Abstract
When security-constrained unit commitment (SCUC) was directly solved by mixed integer programming algorithm, the calculation efficiency would considerably decrease, and when SCUC was solved by Benders algorithm, it led to the problem that the solution efficiency would decrease due to the algorithm shock and the restriction of system scale. A new Benders algorithm-based method to solve SCUC was proposed. Based on Benders algorithm, by means of adding the link to correct the constraint of out-of-limit after the iteration of Benders master problem, the search direction of Benders cut could be controlled; by means of adding the link to identify taken-effect constraints the search space of Benders algorithm was reduced, thus the solution efficiency of SCUC optimization could be improved. The effectiveness of the proposed method was verified by simulation results of 6-machine 3-bus system and 54-machine 118-bus system.关键词
