[0002] With the promulgation and implementation of the national policy of encouraging the construction of distributed power sources, more and more new power sources are connected to the power grid in various forms, among which photovoltaic power generation is an important sector of new energy sources. It has changed the top-down power flow of the traditional regional power grid, and its instability and intermittency have also brought new challenges to the safe and stable operation of the regional power grid. The purpose is to ensure the safe and stable operation of the power grid. To absorb as much new energy as possible to reduce the consumption of traditional energy, it is necessary to calculate the power generation of the photovoltaic power station in advance, and then adjust the power generation of the unit so that both new energy and traditional energy can be absorbed to ensure the power grid safe operation, but the current photovoltaic power generation calculation is rough, and can only roughly estimate the power generation throughout the day, while photovoltaic power generation is extremely sensitive to weather, and weather changes in a day can easily make the difference between the actual power generation and the predicted power generation The gap has become very large. In order to ensure normal power supply, the power grid is often connected to more electricity than the predicted value, and the utilization rate of energy is low.
