Research on Optimal Ratio of Wind-PV Capacity and Energy Storage Optimization Configuration of Regional Power Grid

Abstract

Reasonable optimization of the wind-photovoltaic-storage capacity ratio is the basis for efficiently utilizing new energy in the large-scale regional power grid. Firstly, a method of wind-photovoltaic capacity ratio optimization for improving new energy accommodation is proposed, including the evaluation model of new energy accommodation and the model of wind-photovoltaic capacity ratio optimization. An optimal allocation method of Energy Storage for improving new energy accommodation is proposed to reduce the power abandonment rate further. Finally, according to the above method, the optimal ratio of wind-photovoltaic capacity and the optimal allocation of energy storage in the target year of the regional power grid are studied. The results can provide a reference for the subsequent construction of wind and photovoltaic power plants and the region’s allocation of energy storage capacity.
