A distributed photovoltaic regulation method considering safety verification includes acquiring power transmission or power substation equipment limit value, load condition, and distributed photovoltaic aggregation information under equipment, calculating load rate of equipment, calculating total maximum regulation amount or the total over-limit correction amount of distributed photovoltaic power under equipment based on the load rate of equipment and a threshold value, and decomposing total maximum regulation amount or total over-limit correction amount to obtain respective total maximum regulation amount or total over-limit correction amount of each load point; and decomposing respective total maximum regulation amount or total over-limit correction amount of each load point to obtain respective maximum regulation amount or over-limit correction amount of each automatic power generation control unit, correcting respective regulation requirement and generating respective regulation target of each automatic power generation control unit, and sending respective regulation target to each automatic power generation control unit for execution.
