摘要
Abstract
The excessive application of low frequency and low voltage load shedding devices leads to the problem of large load in the device system,which reduces the practicability of low frequency and low voltage load shedding devices.In order to solve this problem,an online decoupling control method of low frequency and low voltage load shedding devices based on improved twin neural network is proposed.By analyzing the frequency characteristics of low frequency and low voltage load shedding devices,this method provides important information for online decoupling control of low frequency and low voltage load shedding devices;On this basis,a hybrid model of low frequency and low voltage load shedding device is constructed,from which a trainable data set is generated,and the load shedding amount of low frequency and low voltage load shedding device system is determined according to the minimum sensitivity of load shedding characteristics of power flow Jacobian ma-trix;In order to improve the control accuracy of the system,the obtained results are input to the improved twin neural net-work,the optimal load shedding amount is trained,and distributed to the load shedding node of the device system,so as to achieve the purpose of cutting off the load,and realize the online decoupling control of low-frequency and low-voltage load shedding devices.The experimental results show that the method has strong practicability through the comparative test of load shedding efficiency and control performance.关键词
