Abstract

Abstract: In order to fully absorb apoplexy and optical DG in active distribution network (ADN) and promote the efficient utilization of controllable resources such as energy storage devices and flexible loads,a two-layer two-stage optimal dispatch based on source-network-load was proposed.In the previous two-tier optimal dispatching stage,the upper level is active power optimal dispatching,and the lower level is reactive power optimal dispatching with DG as reactive power output source,which is solved by binary chaotic bat algorithm.In the real-time dispatching stage,ultra-short-term prediction based on improved data stream on-line segmentation is used to revise the previous dispatching scheme in real time.Finally,a modified IEEE-33 bus system is used as an example to verify the effectiveness of the scheduling scheme.

Key words: active distribution network, double layer optimization, real-time correction, two-stage scheduling, demand side management
