Study on active distribution network dispatch strategy based on dynamic partition optimization

Abstract

The goal of active distribution network (ADN) is to improve the capacity of the existing distribution network for intermittent renewable energy (IRE) generation on the premise of ensuring the reliability of grid operation and power quality. In order to promote the consumption of IRE in ADN,this paper establishes an optimization dispatch strategy of active distribution network with energy storage system and controllable load participating in the regulation.An optimization dispatch strategy-dynamic partition is proposed, and an advanced artificial fish swarm algorithm is proposed to enhance the local searching ability. Finally,the effectiveness of the proposed strategy is verified by the case on an improved IEEE 33 node system.
