Abstract

The invention relates to a load shedding control method and device. Load shedding turns are combined with plant-station priorities to perform load shedding control, a load shedding strategy can be dynamically executed according to different access load turns and plant-station numbers, selective shedding is performed from the first turn of each plant station one by one according to the plant-station priorities, according to whether the residual value P of the total to-be-shed power value after shedding is greater than 0, continuing shedding or ending shedding is selected until the requirement of the to-be-shed power value is met, and different load shedding configuration strategies can be realized. According to the load shedding technical scheme of the invention, different requirements of different application scenes on strategies are met, and the flexibility and universality requirements of the device on the strategy function can be ensured to a great extent.

Description

Technical field[0001]The present invention relates to the field of safety and stable control technology of power systems, and more particularly to a cut load control method and apparatus.Background technique[0002]With the rapid development of the special high pressure, the grid "strong weakness" characteristics, wind power and photovoltaic and photovoltaic network capacity continue to grow, the grid pattern is significantly changed, the power supply structure is profound, in order to protect the power grid Safety and stable operation, the role of security and stability control devices is increasingly important, and applications are increasingly wide.[0003]Due to the difference in the actual situation of the power grid in different regions, the architecture and functionality of the grid of different regions were caused. For safety stability control devices, the load or the number of power supplies and the type of power supply are not the same. There is a big difference in information...
