Title: Contingency Analysis under Deregulated Power Systems
Authors: K. Radha Rani and J. Amarnath and S. Kamakshaiah
Abstract: The electric power industry is in transition to a deregulated market place for power transactions. In deregulated environment, participants are interested in maximizing their own profits, regardless of the system-wide profits. It is perceived that the competition will reduce the price of electricity for retail customers; however, the key issue for participants is related with the price definition to remain competitive. Contingency Analysis of a power system is a major activity in power system planning and operation under deregulated environment. 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. This paper focuses on developing an algorithm for Multiple Line Outage Distribution Factor (MLODF) and to take corrective actions based on sensitivity for multiple outages. The developed algorithm was tested on three test systems; six bus, thirty bus and thirty seven bus test cases. The test results demonstrate that given situational awareness the algorithm provide additional decision support that can be used for remedial actions and/or for recovery after multiple outages. Integrating these into a power system energy management system (EMS) will provide a tool for operators to have a better understanding of the system before and during an extreme condition.
Keywords: Deregulation, Contingency Analysis, Multiple-line outages, power system control.
