Optimization of Grid-Forming Energy Storage Configuration for Voltage Problems Based on Electromagnetic Transient Simulation

Large-scale energy storage can effectively address transient voltage issues arising from the high integration of renewable energy resources. To achieve this, we must investigate optimized configurations for energy storage devices. This paper begin s by constructing the technical characteristics of grid-forming energy storage in a simulation platform and introducing its technical features. Subsequently, a site selection and capacity optimization method specifically designed for grid-forming energy storage is proposed, which includes two components: reactive-voltage sensitivity calculation and iterative optimization algorithm. Finally, we validate the effectiveness of the proposed algorithm by using a case study of the Northwest HVDC sending-end grid of China. This ensures the reduction of repetition and enhances the uniqueness of this paper’s contributions.
