摘要(Abstract)：

当前储能投资成本较高且收益不明确，较难在用户侧规模化推广，如何降低投资成本并提高投资收益是亟待探索的问题。首先提出了用户侧共享式储能的设备结构，对用户的负荷行为进行分析并归类出四类客户。然后，分别从峰谷套利收益、变压器降容收益、投资成本、运营成本4个方面进行量化，以动态投资回报期为评估指标，建立用户侧共享式储能的全寿命周期经济效益评估模型。以典型日峰谷套利收益最大为目标，构建用户侧共享式储能的优化调度模型，对储能充放电策略进行优化。最后，以某工业园区用户为例，从经济性和安全性角度综合分析了用户参与共享式储能方案的投资效益。研究成果对当前储能商业化推广应用具有一定的指导意义。
At present, energy storage is characterized by its high investment cost and indefinite income that hinders its large-scale promotion on the user side. It has now become a problem that demands prompt investigation to lower investment costs and increase profits. Firstly, the equipment structure of user-side shared energy storage is proposed, and load behaviors of users are analyzed and users are divided into four kinds. Secondly, peak-valley arbitrage income, capacity reduction income of transformers, investment cost, and operation cost are quantified. The dynamic return on investment period is used as the evaluation index to establish the life cycle economic benefit evaluation model based on user-side shared energy storage. To maximize peak-valley arbitrage income on a typical day, an optimal dispatching model of user-side shared energy storage is constructed to optimize the charging and discharging strategy of energy storage. Finally, a user in an industrial park is taken as an example to comprehensively analyze the investment benefits of a user-participated shared energy storage scheme from the perspective of economy and safety. The research results are of certain guiding significance to the present energy storage commercialization and application.
