Multi-agent-based urban power grid isolated island black-start system and method

Abstract

A multi-agent-based urban power grid isolated island black-start system and method belongs to the field of operation control of power system field. A plurality of units which can achieve splitting isolated island operation are configured in main power plants in advance, the units are required to be capable of supplying first-class and second-class loads or providing start capacity of other power plants after undertaking auxiliary power load and can guarantee stable operation of auxiliary powers after emergency load shedding; when a power grid system suffers from large disturbance or has a major fault, transformer substation monitoring agents of an affected area and power plant monitoring agents can actively split into isolated island operation states, when the fault is finally evolved into a blackout, all the stable-operation power plant stage and transformer station stage isolated islands in the power grid report respective isolated island operation conditions to a power grid monitoring center agents. The multi-agent-based urban power grid isolated island black-start system and method can greatly shorten power grid black-start time and reduces economic losses and social influences caused by the blackout.

Description

technical field [0001] The invention belongs to the field of operation control in the field of power systems, and in particular relates to a multi-agent-based urban power grid island black start system and method. Background technique [0002] The power system is the lifeblood of a city. Once a large-scale power outage occurs and the city is paralyzed, it will directly lead to huge economic losses, and may even lead to major political events or social unrest. Many blackouts in the world in recent years have shown once again that the threat of blackouts cannot be completely avoided due to the application of advanced technology. After a large-scale power outage accident occurs in the power grid, the power system operators must quickly start the emergency plan for the full power grid outage, carry out the black start of the power grid, complete the grid connection reconstruction, restore the power grid output in the shortest time, and reduce the economic loss and social damage ...

AI Technical Summary

Problems solved by technology

However, after a severe catastrophe occurs in a large-scale power system, due to the unbalance of units and loads in each isolated island, there is no guarantee that there will be isolated islands.

Moreover, due to the uncertainty of the location and scope of the island after the accident, it is difficult to formulate a black start plan for it in advance, so it is necessary to effectively control the formation of the power island
