Power system disturbances and sensitivity analysis methods as a part of contingency analysis

Abstract

There is maximum amount of restructuring, regulation and deregulation and privatization of Electric companies. So, required quantity of energy is not supplied by the utilities to the customers. So, blocking occurs in the market of electrical power system. Due to this reason, transmission lines are operated above their rated limits and also bus voltages are not in a range of their limits. This paper is all about with the types of the changes and disturbances in the electrical deregulated market and solution methods for contingency analysis as a load flow study and sensitivity factor analysis methods. Also case study of IEEE-14 bus test system is carried out with the solution mentioned by sensitivity analysis under the condition of contingency to improve the GSF and LODF of lines. For that purpose AC load flow and real power flow performance index was found out.
