摘要:

共享储能采用统一规划、建设和调度,具有初始投资低、运营风险小、设备质量有保障、利于多重价值的实现等优点,未来有望成为储能和新能源协同发展的主流模式,该模式的持续、健康发展离不开合理、有效政策的支持。本工作分析了我国共享储能发展现状,应用系统动力学方法搭建了光伏和共享储能发展的系统动力学模型;基于某省实际及规划数据,确定模型参数,模拟仿真了在不同配储比例、配储时长、租赁费用、年调度次数等政策情景下的光伏及储能装机规模变化。研究结果表明,共享储能政策的制定需综合考虑新能源规划目标、储能规划目标、系统灵活性需求等因素,积极拓展储能收益来源,使源网荷合理分摊储能成本,才能实现新能源和储能的高质量协同发展。

Abstract:

Shared energy storage adopts unified planning, construction, and scheduling and has the advantages of low initial investment, low operation risk, and guaranteed equipment quality, as well as being conducive for realizing multiple values. In the future, it is expected to become the mainstream model for the coordinated development of energy storage and new energy. The sustainable and healthy development of this model is inseparable from the support of reasonable and effective policies. In this paper, the development status of shared energy storage in China is analyzed, and the system dynamics model of photovoltaic and shared energy storage is established using the system dynamics method. Based on the actual and planning data of a province, the model parameters are determined, and the changes in the installed capacity of photovoltaic and energy storage under different policy scenarios, such as configuration proportion, configuration duration, rental cost, and annual scheduling times, are simulated. The results show that the development of a shared energy storage policy should (1) comprehensively consider the new energy and energy storage planning objectives, system flexibility requirements, and other factors, (2) actively expand energy storage revenue sources, and (3) reasonably allocate energy storage costs to the source, grid, and load to realize the high-quality coordinated development of new energy and energy storage.

Key words: shared energy storage, system dynamics, policy effect
