摘要
针对混合储能在新能源高占比地区的容量配置及运行策略问题,梳理了多种类型储能的技术、经济特性及配置需求。随后,建立基于多场景随机规划及混合整数线性规划的混合储能双层优化配置模型,用于实现混合储能定容选址。在此基础上,建立面向辅助服务、现货市场等市场机制的储能运行优化模型。最后,采取某地等值电力系统进行算例验证分析。结果表明,所提混合储能优化配置及运行策略模型可有效降低地区电网新能源弃电率及净负荷峰谷差率。
This paper focuses on the capacity configuration and operation strategy of hybrid energy storage in areas with a high proportion of new energy.Firstly,it outlines the technical,economic characteristics as well as configuration requirements of various types of energy storage.Subsequently,a hybrid energy storage dual layer optimization configuration model based on multi scenario stochastic programming and mixed integer linear programming is established to achieve fixed capacity location selection for hybrid energy storage.On this basis,an energy storage operation optimization model is established for market mechanisms such as auxiliary services and spot markets.Finally,a case study is conducted to verify and analyze the equivalent power system in a certain location.The results indicate that the hybrid energy storage optimization configuration and operation strategy model proposed in this article can effectively reduce the new energy curtailment rate and net load peak valley difference of regional power grids.
