| Abstract |
With the expanding size of the power system, there is a certain way of finding solutions to maximize the utilization of existing systems and to provide adequate voltage support. For this, power flexibility is needed. A flexible AC transmission system (FACTS), if located optimally, can be useful in providing voltage support and controlling power flow, which in turn results in lower losses in deregulated power system. This paper proposes a method of finding the optimal location of unified power flow controller (UPFC) to relieve congestion using a sensitivity analysis approach by the Fast de-coupled methodology. The impact of these gadgets on line flows and bus voltage profiles has been studied by placement at the line which is the most positive sensitive or more negative sensitive location and placing them optimally with optimal ratings dictated by sensitivity analysis, in order to reduce losses and improve the voltage profile. The effectiveness of the developed algorithm has been tested on an IEEE 14-bus system. |
