面向能源互联网的用户侧分布式储能价值评估

随着能源互联网的发展,分布式储能以其优良的系统灵活性和电力一致性,对推动电力生产和利用方式变革具有重要战略意义。针对用户侧分布式储能,以并网型“分布式光伏+储能”为主要应用模式,以前置运行优化的用户侧分布式储能全寿命周期成本收益分析为基础,提出了基于双粒度储能优化运行策略的分布式储能价值评估模型。以中国某省一般工商业和大工业用户为案例,对负荷特性、电价政策、储能成本和储能技术特性对用户侧分布式储能价值的影响进行敏感性分析,研判用户侧分布式储能未来发展潜力和趋势。

Energy Internet Oriented Evaluation of Distributed Energy Storage Utility in User-Side

With the development of China's energy internet, the distributed energy storage system will surely have a great new development opportunity for its excellent flexibility and power consistency, which is of great strategic significance in promoting electricity production and utility pattern change. In view of the user-side distributed energy storage which takes the grid-connected "distributed photovoltaic+energy storage" as the main application mode, a distributed energy storage evaluation model based on double-granularity optimal operation strategy is proposed, which is built on life-cycle cost-benefit analysis model for user-side distributed energy storage considering its operation optimization in advance. Taking the large industrial and business consumers in a China's province as an example, a sensitivity analysis is made of the user-side distributed energy storage value under the effects of the load characteristics, electricity price policy, energy storage costs and technology characteristics, and the future development potential and trend of the user-side distributed energy storage is predicted.
