Battery storage deployment is realized as one of the significant paths towards the goal of “carbon peaking and carbon neutrality”. In this paper, a novel two-phase large-scale battery storage and renewable energy coordinated control decision making strategy with both short-term and ultrashort-term forecasting of the renewable and load consideration is proposed. To enhance the consumption of new energy, a strategy of wide-area multi-source complementary collaboration is utilized, which, in scenarios where there is significant deviation in the ultra-short-term forecast of solar and wind farms, dynamically optimizes and adjusts power output, transferring consumption space to solar and wind farms with abundant generating capacity. Furthermore, through the spatial-temporal coordination of energy generation and storage, the role of energy storage is fully leveraged to ensure grid safety, thereby further enhancing the consumption of new energy.
