Power grid peak load optimization method

The invention discloses a power grid peak load optimization method. According to the method, the peak load of a power grid is optimized through three measures, namely newly adding photovoltaic installation, implementing demand response and configuring chemical energy storage. The method comprises the following steps of: a peak load optimization model is established, the target function of the model is the minimum total cost of the peak load reduction of a power grid; and then constraint conditions are determined for solving. According to the method, the optimization model with the minimum total cost as the target is constructed, the optimal scheme for peak load optimization is provided through comparison, the overall efficiency of a power system is improved, and a feasible theoretical method is provided for regional peak load development trend analysis and coping strategy formulation. 本发明公开了一种电网尖峰负荷优化方法，通过新增光伏装机、实施需求响应和配置化学储能三个措施优化电网尖峰负荷，首先建立尖峰负荷优化模型，模型的目标函数为电网尖峰负荷削减的总成本最小，然后确定约束条件用于求解。该方法构建以总成本最小为目标的优化模型，对比提
