TLDR
In this article, a MATLAB program that screened and ranked all the n-2 and n-1 contingencies present in IEEE 14-bus system has been used to determine the severity of each outage case, the researchers used Performance Indices specifically the Voltage-Reactive Performance index as an indicator whether the outage happened is critical or not.Abstract:
Contingency Analysis is an analysis of a power system to determine the severity of an outage to the whole system. In this paper, the researchers made a MATLAB program that screened and ranked all the n-2 and n-1 contingencies present in IEEE 14-Bus System. Over all, IEEE 14-Bus system has 5 generators and 20 transmission lines comprising of 325 possible outage cases. The researchers used Fast Decoupled Load Flow method for the load flow analysis of the system for each outage case since it is more simplified than other methods. Also, to determine the severity of each outage cases, the researchers used Performance Indices specifically the Voltage-Reactive Performance index as an indicator whether the outage happened is critical or not. With this MATLAB program, power system operator can easily determine the severity of the outage of a given power system and what action must be done.read more

Reactive Power Considerations in Automatic Contingency Selection
Abstract: On-line steady-state security analysis requires the evaluation of the effects of a large number of possible contingencies on a power system. Almost all contingency analysis programs have had to rely on a list of selected contingencies to be studied. The brute force approach of testing all contingencies every time an evaluation of the system performance is needed, becomes prohibitive due to its computational burden. A particularly attractive technique is to utilize a fast, approximate method to select the few contingencies that actually affect the security of the power system and then analyze only these cases in more detail. The contingency ranking and selection methods presented in the literature have all ranked outage cases on the basis of transmission line overloads. This limits the usefulness of these technqiues as contingencies that cause only voltage problems are totally overlooked. This paper shows that there is little correlation between the contingencies that produce line overloads and those that result in unacceptable voltage profiles, further establishing the need for a contingency selection method that is also voltage sensitive. Such a method, using the first iteration of an AC power flow, is presented. It is shown that the method meets both the speed and accuracy requirements for on-line use.
