Abstract

The invention discloses a power supply recovery system and method based on scalable partitions. The problems that in the prior art, power of a fixed power supply recovery partition is limited, and power supply recovery cannot be rapidly carried out are solved. The system comprises a plurality of base stations and micro-grids which form a honeycomb distribution network topology; the base station comprises a bus and an energy storage station, and the bus provides electric energy for the adjacent micro-grids through a voltage transformation device; the micro-grid comprises a power supply station, an energy storage station and a load and can operate in an isolated island manner; the comprehensive regulation and control center is in communication connection with the base stations and controls the base stations to switch the switches of the micro-grids to form a telescopic power supply recovery area according to the load switching condition in the micro-grids to be recovered; and formulating a multi-time-scale and multi-priority power supply recovery strategy. Through the honeycomb-shaped distribution network, the micro-grids are mutually independent and associated to form a telescopic power supply recovery area, so that the power supply recovery speed is ensured, the energy waste can be reduced, and the power distribution mode is flexible.

Description

technical field [0001] The invention relates to the field of power supply recovery, in particular to a system and method for power supply recovery based on scalable partitions. Background technique [0002] When the distribution network fails, how to quickly restore the power supply to the outage users, minimize the outage time, reduce the impact on the outage users, and ensure the power reliability of the power users has become the main issue considered by the power company. The fault recovery of the traditional distribution network mostly relies on the centralized repair and recovery of non-faulty areas such as adjacent feeders or distributed power sources. At present, realizing partition recovery based on network topology and connected source-load characteristics will greatly improve the speed and quality of recovery and reduce the complexity of recovery. Shift to partitioned distributed recovery. [0003] The existing partitioning technology for fault recovery includes...
