Grid Connected Photovoltaic Power Generation Station and It's Influence on Dispatching Operation Mode

As a new type of energy, photovoltaic power generation needs to be connected to the power grid by special lines or public lines, which will change the management mode and power flow structure of traditional power grid, especially bring a lot of technical and management difficulties to power quality, relay protection, automatic safety devices, equipment maintenance and power outages. As the photovoltaic power generation technology come to mature now, the connection of photovoltaic power generation is still in the stage of exploration and the access method, access capacity, access location, voltage level, protection configuration, automatic device configuration and monitoring control technology of photovoltaic power generation is not yet mature to State Grid Corporation of China. Therefore, it is very important to research how photovoltaic power generation connects to the grid and its influence on power dispatching.
