Collaborative Planning of Renewable Energy and Energy Storage Based on Synergistic Environmental Value

After the “double carbon” goal was proposed, China continued to expand the scale of renewable energy (RE). However, energy fluctuations and uncertainties pose challenges for the grid. As a regulatory resource, energy storage is very important to the stability of power system. But differences in policy, resources and demand make renewable energy sites different in demand. The collaborative environmental value of different scale sites after the implementation of energy storage is also different. In view of this, the collaborative planning method is studied in this paper. Firstly, the influence factors of collaborative environment value are analyzed. Secondly, the renewable energy storage planning model is established to solve the storage needs of different regional sites. Finally, the case verifies the validity of the planning model based on environmental values, providing insights into regional storage schemes.
