Safety Impact of Large-Scale Distributed PV Power Access to Power Grids

Abstract

 Abstract—Photovoltaic (PV) power generation is the fastest growing part of distributed generation technologies. Large-scale PV power connected to the grid is bound to the safe operation of the grid to bring new problems and challenges in China. Based on PSASP, combined with large-scale PV power access to the actual grid, this article establish PV model, do research on the characteristics of large-scale PV power stations and network system. In this article, the characteristics of PV grid-connected systems, stability and other issues accessing to large-scale PV system are discussed.
