The invention discloses a low-voltage distributed photovoltaic control method and device and a medium. The method comprises the following steps: monitoring operation information of photovoltaic users and energy storage equipment in a control area in real time after receiving a power grid peak regulation index; according to the power grid peak regulation index, a regulation and control target is calculated and decomposed to generate transformer area regulation and control indexes of a plurality of transformer areas; under the condition that the energy storage equipment is configured in the transformer area, charging or discharging the energy storage equipment according to the transformer area regulation and control indexes and the total charging power of the energy storage equipment in the operation information, and generating a first day-ahead regulation and control scheme; otherwise, determining a regulation and control sequence according to the regulation and control priority of the photovoltaic users in th
