Method, device, equipment and medium for reducing network loss of power distribution network through energy storage device

The invention relates to a method and device for reducing power distribution network loss through an energy storage device, equipment and a medium. The method comprises the steps of obtaining optimization reference data of a power distribution network; calculating optimization index data according to the optimization reference data; according to the optimization index data and a preset objective function, performing optimization control on active and reactive output of the energy storage device by taking the minimum distribution network loss as an objective. Optimization reference data of a power distribution network are collected to calculate optimization index data, optimization control is carried out on active and reactive output of an energy storage device with the minimum loss of the power distribution network as the target, and the energy storage active and reactive output is controlled at the same time, so while active load adjustment and electric quantity and capacity electric charge reduction are ach
