과도안정도 에너지 마진 향상을 위한 다기의 TCSC 적정량 실시간 산정

Abstract

his paper presents power system transient stability the three parts, the first part is margin using by ANN. To get a method for real-time estimation of TCSC reference quantity in order to enhance the energy margin using artificial neural network in multi-machine system. This paper has to determine the lines to be installed by TCSC. The seconds is to estimate the energy the critical energy for training, we use the potential energy boundary surface(PEBS) method which is one of the transient energy function(TEF) method. And the last is to determine the TCSC reference quantity. In order to make training data for ANN in this step, we use genetic algorithm(GA). The proposed method is applied to 39-bus, 46-line, 10-machine model system to show its effectiveness.
