Aiming at the problem that the complex coordination relationship of the sendingend power grid with high proportion of new energy and pumped storage combined power generation may lead to insufficient new energy consumption capacity, an energy balance optimization control method of the new energy sendingend power grid based on variable speed pumped storage is proposed. Firstly, the operating characteristics of variable speed pumped storage units are studied, and the active and reactive power output characteristics of variable speed pumped storage units based on frequency converter control are analyzed. Secondly, the variable speed pumping is used to analyze the improvement of new energy generation capacity, and the energy balance optimization model of the new energy sending end power grid is established. Then, the quantum particle swarm optimization algorithm is improved, and the energy balance optimization control algorithm of the new energy sending end power grid is proposed. Finally, with reference to the delivery mode of new energy base in a certain area of Northwest China, a typical scenario of variable speed pumped storage power station and conventional pumped storage power station cooperating with new energy is constructed. The improved new energy consumption capacity of variable speed pumped storage power station and conventional pumped storage power station is compared. The simulation results show that the energy balance optimization control method of the sending end power grid based on variable speed pumped storage can improve the utilization rate of new energy and play a significant role in improving the level of renewable energy consumption.
