| description | The invention provides an optimal control method for promoting the efficiency of multiple photovoltaic modules in a partial blocking condition. The optimal control method comprises the following steps: step one, using a bidirectional power converter to establish an efficiency optimization structure network of the multiple photovoltaic modules in the partial blocking condition; step two, analyzing a power treatment strategy of the optimization structure network; and step three, determining an objective function and constraint conditions, and establishing an optimal linear model, so that the energy loss of the power converter is minimized on the basis of realizing power redistribution of each photovoltaic module, and the total energy efficiency is improved.
本发明提出了种局部遮挡情况下多光伏组件效率提升的最优控制方法，包括：步骤1，利用双向功率变换器建立局部遮挡条件下多光伏组件效率优化结构网络；步骤2，分析优化结构网络的功率处理策略；步骤3，确定目标函数以及约束条件，建立最优线性模型，在实现各光伏组件功率重分配的基础上，使功率变换器能量损失最小化，提高总体能量效率。 |
