Abstract
A coordinated control scheme based on voltage sensitivity partition is proposed to solve the voltage problem caused by the access of distributed photovoltaic(PV)with high permeability to distribution network.The basic strategy is to partition the PV users that are connected to distribution network according to the voltage sensitivity factors obtained from the network topology.When a voltage violation problem occurs,the PV inverter's own reactive power capacity is used to perfporm a reactive power autonomous control;if the inverter's reactive power capacity in the voltage violation region is exhausted,then the other inverters along the feeder will perform reactive power coordinated control;if all the reactive power control cannot solve the voltage problem,then a coordinated control on the substation level will be adopt?ed,which can regulate the tap of the substation on-load tap changer and the regional PV active output curtailment.Fi?nally,the validity of the proposed scheme is verified by a simulation model.关键词
