Improvement in Power Transfer Capability of an Interconnected Power System without Contingency

Gurjot Singh, Harsh Sharma

Abstract: Power Transfer Capability is an important index in todays power markets with large volume of inter-area power exchanges and wheeling transactions taking place on hourly basis. Its computation helps to achieve a viable technical and commercial transmission operation. The aim of my research was to evaluate power transfer capability and also to improve it using compensation technique. Load flow of 30-bus system was carried out considering normal conditions without contingency. Base and optimized results shows that how compensation helps to improve system condition and tie-flows. Parameters like voltage magnitude, L-index, MW losses, MSV are computed to analyze the system performance.
