The invention discloses a voltage control method for stabilizing photovoltaic power generation uncertainty and a related device. The method comprises the following steps: constructing a day-ahead source-load-storage voltage control model; the minimum operation cost and the minimum node voltage of the power distribution network are taken as objective functions, a double-objective problem is converted into a single-objective problem based on fuzzy multi-objective conversion, and a day-ahead source-load-storage voltage control model is solved, so that a photovoltaic power generation power fluctuation interval is determined; a first-order ETP equivalent thermodynamic model is adopted to analyze the air conditioner cluster virtual energy storage mathematical model and the control strategy, and a control mathematical model considering the air conditioner cluster virtual energy storage real-time collaborative optimization voltage is constructed; and determining an optimal economic operation objective function and a
