Research review of voltage cooperative control in distribution system with high photovoltaic penetration

High photovoltaic penetration is one of the typical features of future renewable energy power system, which will face the challenges of frequent fluctuation of photovoltaic output and poor communication performance. Furthermore, the newly integrated photovoltaic inverters do not well align with the existing voltage management system of distribution system, it is necessary to cooperate the control of the two. Under this background, a comprehensive and systematic review of voltage cooperative control of distribution system with high photovoltaic penetration is carried out. The intension and definition of distribution system with high photovoltaic penetration and the urgent contradiction to be solved in voltage cooperative control are outlined. Focusing on the voltage cooperative control issues of cooperative control strategy of distributed photovoltaic inverters and the coordination of inverters and traditional voltage control devices, the related research status of distribution system with high photovoltaic penetration is reviewed. The theoretical and technical issues to be solved in the field are prospected.
