Title: Contingency Analysis & Ranking with special reference to Yemen National Grid
Author: Salih, Mohamed Ali
Abstract: In this work, the contingency analysis problem with reference to the Yemen National Grid is investigated. On-line steady-state security analysis requires the evaluation of the effect of a large number of possible contingencies on a power system, and the time involved reduces the usefulness of the analysis. A complete analysis using full load flow methods consume, too much time, while on the other hand approximate methods are faster but offer compromised accuracy . The solution to this dilemma is to find a way to select contingencies in such a way that only those that are likely to result in an overload or voltage limit violation will actually be studied in detail and the other cases will go unanalyzed. In light of these constraints, the system performance may be quantitatively evaluated in terms of indices reflecting the severity of out-of-limit voltage values or line overloads resulting from a particular contingency. A sample system was used here to test the 1P1Q and the DC method. This method was then tested on a full power system representing a utility of The Yemen National Network.
