Abstract
Wind-photovoltaic clustered grid-connected gives a new challenge to reactive voltage control.By analyzing the characteristics of clustered development,weak power grid access,long distance delivery in China's new energy development,this paper proposed a reactive voltage coordination control strategy of unit-station-cluster-network.This strategy is divided into four levels control-unit,station,cluster and network based on the idea of multilevel coordination and step-by-step refinement.Network level is the highest level control,and each level accepts the control signal from higher level and executes the corresponding action,meanwhile,sends out control signal to the lower level,in order to achieve the safe and stable operation of full network voltage and to realize the maximum output as much as possible.Finally,some platform was simulated to verify the effectiveness and accuracy of the strategy.关键词
