Abstract

The invention discloses an optimal scheduling method and device for a flexible interconnection power distribution network. The method comprises steps of determining a flexible interconnection device of the flexible interconnection power distribution network; utilizing active and reactive power of a converter of the flexible interconnection device as a decision variable, taking the minimum comprehensive power supply cost and the minimum voltage deviation of the flexible interconnection power distribution network as optimization objectives, performing predictive control according to a classic model, and establishing an intra-day optimal scheduling model of the flexible interconnection power distribution network, wherein the intra-day optimal scheduling model comprises a prediction model androlling optimization, the prediction model adopts a voltage sensitivity method to predict a voltage of each node in the flexible interconnection power distribution network, and the rolling optimization adopts an adaptive dynamic weight method to process a multi-objective optimization problem containing comprehensive power supply cost and voltage deviation. The method is advantaged in that a problem that research and analysis of operation scheduling of the flexible interconnection power distribution network in related technologies are not enough to meet the current technical requirements is solved.

Description

technical field [0001] The present application relates to the technical field of optimal operation of active distribution networks, and specifically relates to an optimal scheduling method, storage medium and processor of flexible interconnected distribution networks. Background technique [0002] Compared with the traditional distribution network of "closed-loop design and open-loop operation", the flexible interconnection distribution network can greatly improve the reliability of power supply, improve the quality of power supply, and ensure the full consumption of highly permeable distributed generation (DG). [0003] In the prior art, many studies have been carried out on the operation scheduling of the flexible interconnected distribution network, but most of them adopt deterministic models without considering the uncertainty of renewable energy and load. The specific analysis is as follows: [0004] 1. Although the time scale of the refined model can weaken the influen...
