Source-load-storage Control Strategy and Optimization Configuration of Energy Storage based on Time-of-use Electricity Price

Energy storage is an important measure to solve renewable energy consumption and improve the reliability of system operation. Different operation modes, typical load characteristics, and renewable energy output characteristics affect the energy storage capacity configuration results. In this paper, the optimal configuration model of energy storage capacity is established to minimize the configuration capacity of system energy storage based on the actual demand of the power grid. Then, under the constraints of power balance, renewable energy consumption, charge and discharge of energy storage system and economy, the source-load-storage control strategy based on time-of-use electricity price is proposed, and the optimization model is solved. Finally, an example is given to analyze and verify the effectiveness of the proposed model.
