Abstract: The Primary objective of this paper is to understand the stability of Power System. In this study we will explore the security threats of power system as well and also determine the disturbance level in unsafe executions. In this modern era of time the power stability is most necessarily required factor for society, but due to some indecisive reasons the power is not being supplied as per the demand and the evaluation of voltage supplied is become very tricky. In this paper we will study and discuss various aspects of power system stability.
