Problems solved by technology

[0002] Part of the A+ area of ​​the urban distribution network requires highly reliable power supply. The existing centralized fault handling of the main station is difficult to meet the needs of rapid response. Although the local distributed fault handling can achieve the purpose of fast action in time, the behavior is single. It cannot cope with changes in the operating status of the distribution network, and the network scale and complexity of the distribution network are continuously increasing, and various types of automatic terminal devices with new functions are gradually connected, and the cooperation logic between the terminals is encountered during the operation process. Frequent adjustments are required, and it is difficult to test the operation strategy on site to confirm whether it is correct
This poses a challenge to the integration of the two networks (smart grid and power Internet of things) and the access of distributed power sources to the operation control of the distribution network and high reliability power supply

Abstract

The invention discloses a method and system for regional autonomy and rapid response of a distribution network. The system includes a distribution automation main station and a plurality of edge intelligent terminals set corresponding to a single distribution network operating state sensing node. Each edge intelligent terminal performs edge calculation of the node to obtain The operation characteristic data is transmitted to the distribution automation main station to calculate the operation situation of the whole network. The distribution automation main station determines the regional operation strategy according to the situation calculation result; the edge intelligent terminal forms an autonomous area according to the regional operation strategy information, and each edge in the autonomous area The intelligent terminal controls the operation of the network source, load and storage of the node according to the regional operation strategy information, the network source load storage operation status information of the node and other node areas in the autonomous area, and feeds back the operation control process and result data to the power distribution automation master. After analysis by the main station of distribution automation, the operation strategy of the distribution network is maintained or adjusted. The invention can improve the power supply reliability and fault handling capability of the distribution network.
