摘要：

在市场化环境下，建设充分反映储能特点的市场机制对储能产业的发展意义重大。储能对能量状态的需求是具有弹性的。然而，现行的市场机制不利于储能申报该交易意愿，未能充分发挥储能灵活性优势。由此产生了一种储能灵活能量状态的运行方式，其特点是松弛了优化时段末尾的能量状态约束，从而增加储能在市场中的收益。该文系统阐述了储能灵活能量状态运行方式的原理和特点，设计了相应的新型日前电能量市场报价机制，建立了市场调度模型。该机制允许储能申报能量状态需求响应曲线和充放电成本，由系统运营商在出清中确定储能的分时充放电功率和最终能量状态。最后通过算例证明新机制能保证社会福利最大化，同时降低储能的市场风险，提高储能收益。
