摘要: 随着两部制电价带来的机遇和储能本身技术经济性的不断提升,用户配置储能系统可获得巨大的经济效益。为挖掘储能系统收益潜力,在用户负荷最大需量下界分析计算的基础上,提出了一种考虑最优收益的储能系统优化运行模型。该模型以储能配置后的负荷最大需量和充放电功率为变量,综合考虑储能系统运行和寿命约束、变量自身约束等,并通过所提出的辅助变量,将非线性优化运行模型转化为线性模型,降低了求解难度。最后应用该模型方法,对北京和上海2个典型地区的储能系统收益进行了分析。

Abstract: With the rising opportunities from the two-part tariff and the development of energy storage, massive economic benefits will become available for customers by installing energy storage system. In order to explore the economic potential of energy storage system, based on the calculation of the lower bound of the maximum load at demand end, this paper proposes an optimal operation model of energy storage system to achieve the maximum benefits. In this model the maximum load demand and energy storage power are chosen as the control variables, and the energy storage system operation and lifespan, variable association, etc. are taken into full consideration as the constraints. With the aids of the proposed auxiliary variables, the nonlinear optimization operation model is transformed into a linear model, which greatly reduces the complexity of solution. Finally, the model has been implemented successfully in Beijing and Shanghai regions to analyze the benefits of energy storage system in the typical scenarios.
