Abstract: Among them, the construction of distributed photovoltaic on the roof of the whole county (city and district) is an important measure to realize the two national strategies of "carbon peaking, carbon neutralization" and Rural Revitalization. Large scale distributed photovoltaic access to the power grid will have a certain impact on the operation of the power grid and bring certain pressure on the overall consumption of green energy. In order to strengthen the unified control of distributed photovoltaic and promote the coordinated operation of distributed photovoltaic and large power grid, it is necessary to build a distributed photovoltaic dispatching management system, orderly access a large number of distributed photovoltaic, and build a system with transparent information, flexible regulation and A new distributed new energy dispatching management system based on network source interaction.
