Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] figure 1 Shown is the overall structure of the micro-grid control and management system of the present invention, such as figure 1 As shown, the structure of the present invention is a tree structure from top to bottom, and the interior of the middle coordination layer is a connected ring structure. The highest level organization layer is composed of micro-grid management center; the intermediate coordination layer is composed of distributed energy grid connection interface, protection switch control device and existing distribution network protection device; the low-level execution layer includes each distributed energy source controller and protection switch . The control accuracy of each layer increases step by step from top to bottom, and the artificial intelligence decreases step by step.

Abstract

The related control and management system for mini power network comprises: the top organization layer to start system and send connection command to next layer for channel building, the middle coordinate layer as connected loop structure to receive command from last layer and start to build communication channel, and the bottom execution layer to control distributed energy combination when the middle layer decides the energy fit to be combined. Wherein, from top to bottom, the control precision increases successively, while the AI level decreases successively.

Description

technical field [0001] The invention relates to a distributed energy source and a power network monitoring system, in particular to a micro-grid control and management system. Background technique [0002] At present, the power network, especially the distribution system automation management, consists of the distribution automation system master station (ie monitoring center), distribution automation sub-station, substation monitoring system, comprehensive monitoring instrument, meter reading concentrator and distribution control unit theoretically. and so on. The master station of distribution automation is responsible for the monitoring and control of the distribution network in the whole area, and completes the collection and arrangement of the data of each substation, all switching stations and feeders in the whole urban area, and uploads them to the man-machine workstation, and the operator completes the monitoring and control of the system control tasks. The distrib...
