The invention discloses an energy management method and system for a household optical storage and charging system considering battery aging. The method comprises the following steps: acquiring historical vehicle data of a monitoring area; performing clustering analysis on the historical vehicle use data to obtain four typical vehicle use days; constructing an initial mixed integer linear programming model, and constraining the initial mixed integer linear programming model to obtain a target mixed integer linear programming model; solving the target mixed integer linear programming model to obtain the optimal battery discharge depth of the corresponding vehicle use typical day; based on the optimal battery discharge depth, determining the battery cycle index of the corresponding vehicle use typical day; and performing probability weighting on the battery cycle index to obtain the theoretical service life of the battery. According to the invention, the discharge depth of the energy storage battery and the discharge depth of the power battery of the electric vehicle in the household optical storage and charging system can be reduced, the service lives of the energy storage battery and the power battery of the electric vehicle are prolonged, and effective support is provided for energy management and optimized operation of the household optical storage and charging system.

    本发明公开了一种考虑电池老化的户用光储充系统能量管理方法及系统,该方法包括:获取监测区域的历史用车数据;对历史用车数据进行聚类分析得到四种用车典型日;构建初始混合整数线性规划模型,并对初始混合整数线性规划模型进行约束,得到目标混合整数线性规划模型;对目标混合整数线性规划模型进行求解,得到对应用车典型日的最优电池放电深度;基于最优电池放电深度,确定对应用车典型日的电池循环次数;对电池循环次数进行概率加权,得到电池理论寿命。本发明能够减少户用光储充系统中储能电池放电深度和电动汽车动力电池放电深度,延长储能电池和电动汽车动力电池的使用寿命,为户用光储充系统的能量管理与优化运行提供有效支撑。
