| 摘要: |
| 电化学储能(electrochemical energy storage, EES)内部的多种功能性老化行为是影响EES规划决策以及经济性评估的重要因素。针对独立运营模式下EES同时参与电能量和调频市场的容量配置问题，首先提出计及功能性衰减的EES两阶段容量优化配置决策模型。第一阶段模型以EES期望寿命周期内收益最大化为目标进行EES容量优化配置；第二阶段模型考虑EES寿命和功能性老化行为约束，以日运行利润最大化为目标优化各运行年内EES运营决策。然后采用多参数规划理论方法对两阶段模型进行联合优化求解，以获得独立运营模式下EES的配置容量及其期望寿命。最后通过算例仿真分析了EES的功能性老化行为对其经济寿命及容量配置的影响，验证了所提模型和方法的有效性。 |

| Abstract: |
| The various functional aging behaviors within electrochemical energy storage (EES) are important factors affecting EES planning decisions and economic evaluations. First, a two-stage capacity optimization decision model for EES is proposed considering functional decay to address the capacity allocation issue of EES participating in both the electrical energy and frequency modulation markets in an independent operational mode. The first stage model optimizes the allocation of EES capacity with the goal of maximizing benefits within the expected life cycle of the EES; the second stage model optimizes the EES operational decisions within each operating year with the goal of maximizing daily operating profit considering the constraints of EES lifespan and functional aging behavior. Then, the configuration capacity and expected lifespan of EES in an independent operational mode is obtained using the multi-parameter programming theory method to jointly optimize and analyze the two-stage model. Finally, the impact of functional aging behavior of EES on its economic life and capacity configuration is analyzed through numerical simulation and the effectiveness of the proposed model and method is verified. |
