Review on Risk Assessment of Power System

Abstract

With electric power system becoming more and more complex and intelligent these days, its uncertainty also increases. This paper classifies the references of the risk assessment on power system from the aspects of evaluation hierarchy, evaluation category, evaluation model, power system status, time and simulation algorithm. The purpose of this paper is to reveal the research status and compared the advantages and disadvantages of the methods used. And the future development of risk assessment on power system is also prospected.
