Abstract: Because of human concern for energy security and environmental deterioration, making full use of renewable energy has been a global consensus. Power generation with large-scale renewable energy such as solar and wind energy has become the development trend of new power systems, resulting in increasingly prominent impact on power systems. Therefore, great concerns are given from academic and engineering areas of all countries. The purpose of this paper is to review the globe status of large-scale photovoltaic（PV） power generation, explore the factors affecting the interaction between solar power generation and power system, refine academic and engineering problems, and propose ideas for future research and development. From the perspective of power system planning, simulation, dispatching and control, this paper discusses the modeling and simulation of large-scale photovoltaic power generation, impacts of large scale PV integration on dynamic and static characteristics of power system, and key technologies about large scale PV power generation delivery and consumption. Meanwhile, suggestions for further research are proposed from the authors’ point of view, offering reference for readers.
