Human concerns energy security and worries environmental deterioration, which makes full use of renewable energy, become a global consensus. Such solar, wind as the representative of the large-scale grid connected power generation with renewable energy has become an irresistible trend of development of new power system, has deep influence on power system, and the academe and engineering give great attention. The purpose of the paper is review of domestic and foreign large-scale photovoltaic research present situation, which is aim to explore the factors on affecting the interaction between solar power generation and power system, refine the academic and engineering problems, and sort out the next step development ideas. From the power system planning, simulation, scheduling and control of angle, this paper lays emphasis on discusses in the modeling and simulation of large-scale PV systems, effects of large-scale photovoltaic (PV) accessed to the dynamic and steady state characteristics and the key technology of large-scale photovoltaic delivery and consumptive analysis.
