The invention provides an optimal scheduling method, device and equipment for a distributed photovoltaic system in a power distribution network. The method comprises the following steps: acquiring initial operation parameters of a target power distribution network; the photovoltaic access quantity of each node in the target power distribution network is acquired, and the photovoltaic access quantity of each node is determined based on an output power model of a preset photovoltaic panel; inputting the initial operation parameters and the photovoltaic access quantity of each node into a pre-constructed optimization scheduling model, and performing solving based on a preset constraint condition to obtain a scheduling scheme after optimization of the target power distribution network; wherein the optimal scheduling model comprises a photovoltaic capacity model and an active loss model, and the preset constraint conditions comprise a system power flow constraint of the target power distribution network, a node po
