Study on the Influence of Distributed Photovoltaic Grid Connection on Power Grid Operation
Distributed photovoltaic grid-connected system can disperse power generation,reduce the burden of traditional centralized power plants,reduce the transmission pressure of power grid,improve the power factor of power grid,improve the load characteristics of power grid,and then improve the stability and reliability of power grid.The development of distributed photovoltaic grid-connected system has promoted the upgrading and transformation of grid technology to a certain extent.However,due to the uncertainty and intermittent characteristics of photovoltaic power generation,the grid voltage,frequency and other parameters may be affected after the distributed photovoltaic grid-connected system is connected.By studying the influence of distributed photovoltaic grid connection on power grid operation,appropriate distribution technology and control means are adopted to meet these challenges,ensuring power quality and safe and stable operation of power grid.
