Embodiments of the present application provide a distributed photovoltaic power grid-connected control method, apparatus, apparatus, and storage medium. The distributed photovoltaic power grid-connected control method comprises the following steps of: acquiring the grid-connected electric energy demand of the user side and the energy storage information of each photovoltaic power source of the user side in a first specified period of time. The total number of grid-connected opportunities and the power supply potential value of each photovoltaic power supply to grid-connected opportunities aredetermined according to the grid-connected power demand and energy storage information of the user side. Distributing grid-connected opportunities to each photovoltaic power source according to the power supply potential value of each photovoltaic power source to the grid-connected opportunities; Controlling the photovoltaic power supply to obtain grid-connected opportunities for grid-connected power supply. Embodiments of the present application enable each user-side photovoltaic power source to participate in grid-connected power supply, thereby giving full play to the energy-saving role ofthe distributed photovoltaic power source and effectively reducing energy waste.
