Optimal Operation of Distribution Network Based on Optical Storage Power Supply

The random fluctuation caused by large-scale PV access and the drastic fluctuations in electricity supply and demand caused by changes in solar irradiance have brought great pressure to the stable operation of the power grid. In view of these problems, scholars from different countries have carried out a series of researches, and proposed distribution network optimization strategies such as static var compensators, shunt capacitor banks, static var generators and OLTC, but all of them have limitations. In this paper, the operation mechanism and scheduling strategy of the PV storage power supply system are deeply explored, and a reactive voltage optimization strategy of the distribution network integrating the coordination mechanism of the PV storage power supply is designed, and the second-order cone programming model is used to achieve efficient solving, and the effectiveness of the strategy is verified, and the problem of voltage over-limit of the grid node is solved.
