摘要/Abstract

摘要： 随着智能电网的发展，用户的用能需求呈现多元化，对用户侧储能系统的经济性分析也需要考虑用户的多元用能需求。为此，考虑用户的热能需求，在用户侧引入热储能，与电储能一起构成热/电综合储能系统，并构建了其数学模型；然后，建立了该综合储能系统的经济模型，给出了其初始投资成本、年均成本和年收益的计算方法。算例部分通过对不含热储能的场景和考虑热储能的场景分析，比较了两者的经济性。结果表明，引入热储能系统虽然会提高初始投资成本和年运行成本，但也会提高整个储能系统的经济性，使储能系统的投资回报年限缩短，说明了在传统电储能系统引入热储能形成与热/电综合储能系统的必要性和有效性。

Abstract: The demand for energy gradually diversifies on user side along with the development of smart grid. Therefore, demand for diversified energy on user side needs to be taken into account based on economic analysis of electrical energy storage system (ESS). This paper firstly introduces thermal ESS to form an electrical/thermal comprehensive ESS together with electrical ESS considering the users’ demand for thermal energy. Then the economic model of the comprehensive ESS is built and the initial investment cost, average annual cost and annual earnings of new ESS are analyzed. A test case including two scenarios in which the first does not have thermal ESS while the second takes it into consideration is given to compare the economic performance. The results show that introducing thermal ESS will improve the initial investment cost and annual operating cost, but the whole economy of ESS will rise, thus shortening the life of return of investment, which illustrates the necessity and effectiveness of introducing thermal ESS.
