大规模风电接入的电力系统优化调度新方法
A New Optimized Dispatch Method for Power Grid Connected With Large-Scale Wind Farms
摘要
Abstract
In allusion to such features of wind power as counter peak-shaving,uncertainty and intermittence,a peak-shaving benefit model of hydropower is built,and combining with price models of thermal and wind generation operation a new type of dynamic multi-objective optimized dispatch model considering unit commitment is constructed.To cope with the trouble that in multi-objecitve optimization problem the particle swarm optimization (PSO) algorithm falls into local optimum and to improve its efficiency,a new optimized dispatch method based on priority ordering and multi-objective particle swarm optimization algorithm with multi-swarm co-evolution (MOPSO-MC) is proposed,namely the optimal unit commitment is determined by priority ordering and the load distribution is divided into two layers and then solved by MOPSO-MC.Applying the proposed method to optimized dispatch of Gansu power grid connected with large-scale wind farms,the results show that the proposed method and models can offer a kind of countermeasure for the operation of grid-connected wind farms.关键词
