Transient Stability Enhancement of Power System Using Intelligent Technique
In this paper, Automation of a power system fault detection using multi resolution analysis (MRA) wavelet transform is proposed and the various coefficients obtained from wavelet transform are given as an input to the probabilistic neural network (PNN). This PNN will classify and find the nature of fault occurring. Later, the decisions obtained from the output of PNN can be used to tune the pow...
متن کاملDirect Transient Stability Assessment of Stressed Power Systems
This paper discusses the performance of critical trajectory method (CTrj) for power system transient stability analysis under various loading settings and heavy fault condition. The method obtains Controlling Unstable Equilibrium Point (CUEP) which is essential for estimation of power system stability margins. The CUEP is computed by applying the CTrjto the boundary controlling unstable equilib...
متن کاملAn Extended Bcu Method to Power System Transient Stability Assessment
This paper shows that under some circumstances the so called BCU method may not be able to find the true CUEP for a specific fault-on trajectory of a power system. The reasons to that malfunction are analysed, and a methodology than can improve the capability of the BCU method to successfully find the CUEP is presented. Finally, several applications of the proposed method to power electrical sy...
متن کاملTransient Stability Analysis of Power System with Photovoltaic Systems Installed
The impact of large-scale grid-connected PV (photovoltaics) on power system transient stability is discussed in this paper. In response to an increase of PV capacity, the capacity of conventional synchronous generator needs to be reduced relatively. This leads to the lower system inertia and the higher generator reactance, and hence, the power system transient stability may negatively be affect...
متن کاملLoss of Load Expectation Assessment in Deregulated Power Systems Using Monte Carlo Simulation and Intelligent Systems
Deregulation policy has caused some changes in the concepts of power systems reliability assessment and enhancement. In this paper, generation reliability is considered, and a method for its assessment using intelligent systems is proposed. Also, because of power market and generators’ forced outages stochastic behavior, Monte Carlo Simulation is used for reliability evaluation. Generation r...
