摘要
In order to make full use of the reactive power regulation capabilities of photovoltaic power stations, energy storage stations, and charging/swap stations, a dynamic reactive power optimization strategy for the distribution network that considers traditional regulation methods and photovoltaic reactive power regulation, energy storage, and charging/swap stations has been established. The article first builds a reactive power optimization mathematical model that comprehensively considers energy storage stations, charging and swapping stations, and photovoltaic stations. Taking into account the volatility of photovoltaics and the coordination between energy storage and the limited timing of charging and discharging stations, a co-evolutionary artificial bee colony is adopted. The algorithm optimizes the multi-station fusion strategy to construct a coordinated reactive power control strategy that can meet the economic and reliable operation of the power grid. Finally, a simulation is performed based on a network example. The simulation results show that the reactive power control strategy proposed in this paper can make full use of the voltage regulation resources of various power stations in the power grid and improve the voltage level of the power grid.
