DEVELOPMENT OF A SENSITIVITY INDEX BASED TECHNIQUE FOR UNIFIED POWER FLOW CONTROLLER PLACEMENT WITH CONTINGENCY ANALYSIS ON NIGERIA 330kV TRANSMISSION NETWORK

📄 Project Abstract

Power system network is designed to operate in a prescribed voltage and frequency for stability and for better power quality. Unexpected contingencies leads to instability related problems in the system. This research develops a sensitivity index based technique with contingency analysis for Unified Power Flow Controller (UPFC) placement for Nigeria 330kV power transmission system. The research employed Newton Raphson power flow method considering multiple contingency analyses which include double line outages, line and load outages, double load outages and load increments. The identification of the severity of the violated bus voltages was achieved through the use of Active Power Performance Index (APPI) and Reactive Power Performance Index (RPPI). The contingency cases were addressed through the sizing and placement of UPFC on the network and simulated in Matlab R2013a environment. The analyses shows that the predominately violated buses and the sizes of the UPFC placed are Maiduguri...
