Research On The Influence Of Photovoltaic Power Generation On Power Supply Capacity Of Distribution Network After The Electricity Selling Side Is Released

This paper is based on the background of further deepening the reform of China's electric power system,and studies the power supply capacity of the distribution network after the opening of the power distribution side and the connection of photovoltaic power generation.The distributed photovoltaic power generation is connected to the power grid at the low-voltage side of the distribution transformer,which can enhance the power supply capacity to some extent.However,after reaching a certain capacity,it will affect the power quality and even bring potential safety risks to the power grid.The subject of this paper is to discuss the competitive environment of power supply subject under the background of power system.By analyzing every turning point in the development of photovoltaic power generation system,this paper concludes that solar photovoltaic power generation will play an increasingly important role in the development of society and human needs.Nowadays,many scholars have gradually entered into the discussion of power supply capacity of the power grid.In-depth studies have been carried out on the traditional power supply of the power grid,but no in-depth and comprehensive research has been conducted on the impact of photovoltaic power supply capacity and operation reliability when it is integrated into the distribution network.Therefore,it is very important to study the power supply capacity of distribution network under the new situation.The conclusion of this paper is that the power supply capacity of the power grid becomes more important in the environment of electricity side release.The release of the electricity side and the access of photovoltaic power generation will bring huge changes to the electricity supply model,and to a considerable extent will also affect the power supply capacity of the grid.
