适应电力市场环境下的电化学储能应用及关键问题

Application and Major Issues of Electrochemical Energy Storage Under the Environment of Power Market

近年来,随着中国储能产业相关政策出台和落地实施,中国电化学储能技术应用快速发展,已在电力系统发输配用各个环节得到示范或商业化应用。但目前电化学储能总体仍处于发展初期,在盈利模式、发展规划、规范管理、消防安全等方面还有待清晰和完善。从发展规模、技术经济性、政策环境等方面阐述中国电化学储能发展现状,提出电化学储能的具体应用场景、商业模式和投资回报机制,并量化分析不同场景下的项目经济性,围绕项目投资属性、发展规划、电价及市场机制、接入和调度运行管理、安全防护、共享平台等6个关键问题分别进行分析,并提出相关建议,促进电化学储能健康有序发展。

In recent years,with the introduction and implementation of relevant policies of energy storage industry in China,the application of electrochemical energy storage technology in China has been developing rapidly,and has been demonstrated or commercially applied in various scenarios of power system.However,at present,as the electrochemical energy storage is still at the early stage of development,there are still a lot of details to be clarified and improved in terms of profit model,development planning,standard management,fire safety and so on.From the aspects of the development scale,technological economy and policy environment,the status quo of electrochemical energy storage in China is reviewed in this paper.The paper also proposes the concrete application scenarios and their return on investment mechanism of electrochemical energy storage,and gives the quantitative analysis of project economy under each scenario.The major issues of energy storage are analyzed with the focus on project investment strategy,development planning,connection and operation management,safety protection,price and market mechanism,and sharing platform respectively.Relevant suggestions are put forward finally,to promote the healthy and orderly development of electrochemical energy storage in China.
