Abstract

The invention discloses a method and device for determining a distribution network operation strategy and a nonvolatile storage medium. The method comprises the steps that generalized stored energy and generalized loads in a power system are acquired, the generalized stored energy is used for storing adjustable resources divided based on a guaranteed absorption angle, and the generalized loads are used for storing adjustable resources divided based on a guaranteed power supply angle; constructing a graph database based on the generalized energy storage and the generalized load; a target model is constructed based on the graph database, and the target model comprises a target function composed of a first target function and a second target function and a first constraint condition; and solving a target function in the target model based on a first constraint condition in the target model, and determining an operation strategy of the AC / DC hybrid distribution network. The technical problem that the calculation efficiency of the power system is low due to the fact that the dual goals of power supply guaranteeing and absorption guaranteeing cannot be taken into account when the operation strategy of the alternating-current and direct-current hybrid distribution network is formulated in the power system in the related technology is solved.
