Abstract

Along with the increase of energy demand and the expanding of the network, the stability of electric power system has become a key problem. In this paper, we will discuss three aspects: a summary of the stability of the power system, the analytical method, and the measures to improve the stability. In this paper, we will summarize the definition of power system stability and the relevant research situation, with emphasis on the analysis of the stability of power system. Then, this paper will discuss the method of analyzing the stability of power system from three aspects, such as stability characteristic and relative index, the classification and features of the stability of power system, the basic method and the way to implement it. At last, this paper will focus on how to enhance the stability of power system. The focus will be on optimizing the structure of energy and electricity generation, the automatic control and protection system of the power system, as well as the application and upgrade of the new electric equipment. Action will be taken to solve the problems of stability in the electricity system. The purpose of this paper is to provide a reference for the practitioners in the electric power industry to improve the stability analysis level and efficiency, and to promote the development and scale of the electric power system.
