Abstract: Contingency analysis is a well known function in modern Energy Management Systems (EMS). The goal of this power system analysis function is to give the operator information about the static security [4]. Contingency Analysis of a power system is a major activity in power system planning and operation. In general an outage of one transmission line or transformer may lead to over loads in other branches and/or sudden system voltage rise or drop. Contingency analysis is used to calculate violations. This paper shows the example on 6 bus power system which gives information of violations & remedial action to remove violations. Detailed studies have been carried out to work out the contingency plans.

- 19 Mar 2018
TL;DR: A Newton-Raphson load flow based approach is presented to perform contingency ranking by computing a voltage performance index (PI), which is classified in secure, insecure and critical classes and then the method proceeds in the decreased order of severity to rank them based on the PI value.
