Design of Automatic Control System for Safe Operation of Key Sections of Power Grid Based on Machine Learning

The problem of transmission section stability overrun is becoming more and more serious.Therefore,an automatic control system for safe operation of key sections of power grid based on machine learning is proposed.According to the theory of the limit learning machine,the prediction error is minimized,and the kernel function is introduced to obtain the critical section accuracy.In order to ensure the safety of power system operation,the power flow method is used to calculate the limit power of power transmission,and the control branches are determined and constrained according to the dispatching strategy.The load frequency of the power grid is controled,the data of collection and exchange business is acquired,the power balance of the key section of the power grid is achieved through the automatic control system,and finally the optimal control is completed.The experimental results show that the design of the system can improve the overall stability of the power grid,and can effectively reduce energy consumption.
