Abstract

The present invention relates to an online simulation modeling method and system for multi-level and multi-area cooperative control load shedding, including: separately modeling the multi-level emergency load shedding collaborative decision-making in multiple areas to form multiple multi-level multi-level load shedding cooperative control strategies model; each of the multi-level load shedding coordinated control strategy models is marked with keywords, and the priority is customized for the multi-level load shedding coordinated control strategy model, and the marked multi-level load shedding coordinated control strategy model is Merge; carry out collaborative operation control on the merged multi-level load shedding collaborative control strategy model, so that information can be exchanged. The invention is beneficial to ensure the stable operation of the power grid.

Description

technical field [0001] The invention relates to the technical field of power system analysis online simulation, in particular to an online simulation modeling method and system for multi-level and multi-region cooperative control load shedding. Background technique [0002] Load shedding control is an important technical measure to deal with serious faults and emergencies of the power grid, and it is also one of the important technical means to ensure the safe and stable operation of large power grids. In the power grid dispatching operation management, the implementation methods of load shedding control mainly include the second line of defense safety and stability control system of the power system (referred to as the safety control system), the third line of defense low-frequency and low-voltage load shedding device, accident pull (limit) power and load control system (orderly power consumption), etc. For various load shedding control schemes and their strategy models, s...
