Research on Rental Storage Pricing Strategy Based on Volatile Price Market

The increase in the proportion of new energy generation and installed capacity of battery energy storage challenges to the economic scheme of the power system. Due to the uncertainty of power demand and new energy generation, the power system needs to establish a feasible energy storage pricing mechanism and scheduling strategy to ensure the profit of batteries in the economic operation process of the power system. In this paper, a more practical energy storage battery cost scheduling curve is proposed. Based on that, an energy storage scheduling scheme based on fluctuating electricity price market is designed with the corresponding rental pricing strategy. The economy of the designed scheme is verified by simulation, and the effect of peak cutting and valley filling is effectively achieved by the storage scheduling strategy.
