Enhancing Stability & Cost Reduction Of Multigrid System By UPFC

Abstract: In some decades, the demand for electrical power has increased but the generation and transmission remained limited due to limited resources and environmental restrictions. The increased demand for electrical power has also increased the complexity in the transmission system. It resulted in the form of the question of stability of power system. Here the stability of power system with possible minimum cost is the main aspect of the present analysis. This problem is solved by using the Solid State devices, known as Flexible AC transmission systems (FACTS) devices. The UPFC is one of the most promising devices of FACTS devices for power system stability with reduction in cost of power. This paper has a comprehensive review on the research and developments in the matter of enhancing power system stability with cost reduction in multigrid network of power supply with the use of UPFC.
