Study on economic analysis and cost recovery mechanism of independent new energy storage power station

Independent energy storage enhances China's energy grid stability and supports carbon neutrality goals. Despite challenges like low utilization and uncertain revenue, an economic analysis of current models and a cost-benefit model have been developed. A cost allocation model considering spot and capacity markets has been proposed to study recovery mechanisms. Simulations of a northwest China power project validate the model, indicating that steering factors between 0.1681 and 0.5955 enable effective revenue allocation and benefit balance among stakeholders while ensuring energy storage profitability.
