Power Flow Optimization of Wind Power Integrated System With Hybrid Power Flow Controller
摘要
Abstract
Hybrid power flow controller(HPFC)is effective in branch power flow overload of wind power integrated system with lower cost compared with unified power flow controller(UPFC).Since the existing research of HPFC power flow op-timization has not considered the branch power flow maximum constraint and wind power uncertainty,a new power flow op-timization model based on scene reduction was proposed for wind power integrated system with HPFC.Power injection model of HPFC was established and corresponding injection power was derived.Then,K-means algorithm was used to re-duce the probability scenes of wind power and load,and the op-timal scene is selected by the CH(+)index.Besides,a multi-ob-jective optimization model was established,which considers the generator operation cost,power loss of the system,branch load rate in normal operation and after N-1 contingencies.Multi-ob-jective particle swarm optimization(MOPSO)algorithm was used to solve the model,and the selection of compromise solu-tion in Pareto solution was realized by the fuzzy satisfaction function.The effectiveness of the proposed method was veri-fied in MATLAB,and the results show that the method can fully consider the uncertainty of wind power and ensure the safe and economic operation of a power grid in different scenes.关键词
