Abstract: With the development of dual carbon targets and new power systems, independent energy storage stations and shared energy storage models have gained industry recognition. The scale of energy storage power stations is also increasing.The importance of provincial energy storage planning is gradually increasing. This article establishes a provincial power grid new energy storage simulation model based on the simulation technology of new energy time series production, with the goal of improving new energy consumption rate. Optimize the energy storage configuration of provincial power grids based on the trend of electricity cost changes. Taking a provincial power grid as an example, analyze its new energy storage configuration plans for 2030 and 2040. Through production simulation and configuration optimization, the consumption level of new energy in the province has been effectively improved, verifying the rationality and effectiveness of the method.
