Power distribution network optimal dispatching control method for enabling distributed power supply to be consumed to maximum degree

Abstract

The invention discloses a power distribution network optimal dispatching control method for enabling a distributed power supply to be consumed to the maximum degree. In order to achieve the target of maximum consumption of the distributed power supply, basic distributed power supply consumption regions are divided step by step through the method according to the installed capacity and peripheral loads of the distributed power supply. During power distribution network optimal dispatching analysis, the boundaries of the distributed power supply consumption regions are dynamically adjusted according to power generation prediction of the distributed power supply. Meanwhile, aiming at the distributed power supply consumption regions, a complex power distribution network topology is simplified based on the graph theory, the load curve characteristics in the consumption regions are analyzed, optimal dispatching time slicing is determined, through the time decoupling technology of dynamic space partitions and multiple time periods in the space dimension and the time dimension, a multi-dimension dynamic optimization problem is equivalent to a time section static optimization problem aiming at fixed space partitions, the problem is solved through an optimization algorithm, and a power distribution network operation optimization strategy is determined through a dynamic programming method.
