Zusammenfassung:The invention provides a confidential distributed optimal scheduling method and system, computer equipment and a medium. The method comprises the following steps: constructing a single-target optimal scheduling model according to actual topology of a smart power grid; converting the single-target optimal scheduling model into a corresponding Lagrange dual model; and according to a subgradient iteration rule, solving the Lagrange duality model to obtain an optimal scheduling solution of the smart power grid. According to the method, noise meeting certain conditions is added to main body node privacy information of communication transmission in combination with the subgradient iteration rule, so that the defects that in the prior art, optimality is easily influenced by privacy levels, all security attacks cannot be handled, the communication efficiency is low, and the cost is high are solved, the optimal scheduling problem and the information security problem of generator sets in a modern smart power grid are e
