Abstract (Summary)
Power Market Analysis Tool for Congestion Management by Silpa Parnandi Master of Science in Electrical Engineering West Virginia University Professor Ali Feliachi, Ph.D., Chair The privatization and deregulation of electricity markets has increased competition and electricity may be produced and consumed in amounts that would cause the transmission system to operate beyond transfer limits - the system is congested. Hence, congestion management is a fundamental transmission management problem. In this thesis, a power market analysis tool is designed for congestion management. The tool creates an interface between PowerWorld c?, a professional software tool to compute power flows, and MATLAB?. The tool helps in analyzing power flow results, batch-processing of large case studies, and providing the user with options to manage congestions. A graphical user interface has been designed to help the user learn and interact with the tool. Based on the generator and load bid data, the tool performs (N-1) security analysis. In case of congestion, the user can choose one of three congestion relief methods. Transmission Line Relief Sensitivity (sensitivities of line flows to load curtailment), Economic Load Management (a product of three indices that measure (i) the sensitivity of the line flow to load curtailment, (ii) the level of customer incentive to cut down consumption, and (iii) the customer’s acceptable range of curtailment), and VAR Support (installment of additional VAR devices). The congestion alleviation methods are explained and tested on a six bus test system and the IEEE 24 bus Reliability Test System.
