Problems solved by technology

[0004] According to the present invention, a method and system based on safety and stability analysis of a human-machine hybrid power system are provided to solve the problem of traditional artificial intelligence (AI) methods such as artificial neural network, support vector machine, and reinforcement learning in the prior art. There have been many researches on the system, but the problems of poor interpretability and low reliability of AI results have not been effectively solved, which greatly restricts the technical problems of its practical development in power system security and stability analysis

Abstract

The invention discloses a safety and stability analysis method and system based on a man-machine hybrid power system. The method comprises the steps that in a man-machine mode, according to a general knowledge base, a training execution agent and an interaction agent, and according to the execution agent and the interaction agent, a special knowledge base is determined, and the man-machine mode is a human dominant-machine following mode; and in a robot mode, according to the special knowledge base, executing a power system task, the robot mode being a mode of robot independence-human supervision. Therefore, a man-machine hybrid power system task execution method is formed, the AI interpretability level and the AI credibility are improved, multi-dimensional cognition of complex power grid operation characteristics is achieved, the safety and stability level of a power system is improved, and the workload of people in actual production is reduced.

Description

technical field [0001] The present invention relates to the technical field of power systems, and more particularly, to a method and system based on safety and stability analysis of a human-machine hybrid power system. Background technique [0002] The power system is an important infrastructure to ensure the production and life of the people, and it is one of the largest and most complex man-made systems in the world. In recent years, with the continuous expansion of the scale of my country's UHV AC-DC hybrid power grid, the penetration rate of renewable energy and power electronic equipment continues to increase, and the safe and stable operation of the power system faces huge risks and challenges. The traditional power system security and stability analysis method adopts the method of "offline pre-decision-online matching", and relies on the pre-deployed security and stability control device to complete the processing of system disturbances to ensure the safe and stable o...
