Abstract

Abstract:

Objectives The construction of a new power system under the dual carbon goals requires energy storage to provide key support. Currently, the construction of new energy storage faces the challenges of high investment cost, long payback period, and low utilization rate. Therefore, a novel optimization method for operating strategies is proposed, aiming to promote the large-scale application and development of energy storage through shared investment cost among multiple parties. Methods Firstly, a daily cost assessment model is established based on the full lifecycle cost of independent energy storage power stations. Then, based on the evaluation model, a multi-market participation framework covering peak-valley arbitrage, frequency regulation, and leasing is designed. Finally, by introducing a cost allocation coefficient, a flexible cost-sharing mechanism for energy storage is established, enabling dynamic optimization of the operation costs of energy storage power stations through leasing market price signals. Results The method increases energy storage revenue, accelerates the cost recovery period, and the cost allocation coefficient can be flexibly adjusted with the development of energy storage technology, thereby improving the strategy’s adaptability and sustainability. Conclusions This study offers an effective pathway for energy storage cost allocation and holds significant implications for promoting large-scale investment in energy storage construction.
