Energy storage capacity planning based on equal integration method considering battery capacity degradation

Configuring energy storage can effectively reduce the abandonment of wind and solar energy, thereby enhancing the consumption capacity of new energy. In this paper, a power grid electricity balance model was established, and the "renewable energy consumption characteristic curve" was extracted. Secondly, an "equal integration principle" optimization model for energy storage and renewable energy consumption was established, incorporating the consideration of battery capacity degradation. Targeting the annual total consumption of renewable energy as the goal, the model seeks a balance between surplus and deficiency in energy storage capacity. Energy storage is configured based on the characteristics of renewable energy, and renewable energy installation is planned based on the principle of system balance, achieving a coordinated planning strategy. This approach realizes the four-dimensional organic unity of "renewable energy characteristics," "renewable energy consumption goals," "energy storage configuration," and "system balance."
