Review of the Influence of Large-scale Grid-connected Photovoltaic Power Plants on Power Grid

Abstract

With the increase of photovoltaic grid-connected capacity, photovoltaic generation will bring many impacts on distribution network. In this paper, the influence of large-scale grid-connected photovoltaic power plants on power grid is reviewed. First, through researching the basic structure and operating characteristic, the paper introduces the operation mechanism of large-scale grid-connected photovoltaic power plants. Then the paper analyzes the influence of large-scale grid-connected photovoltaic power plants on the grid from the distribution grid planning and scheduling, power quality and power system protection. In the end, the paper summarizes some new problems and discusses and prospects the development trends on the large-scale grid-connected photovoltaic power plants.
