Optimal allocation of FACTS devices for provision of voltage control ancillary services

In this paper, the effect of FACTS devices for provision of voltage control ancillary service and allocation of these devices for fair and equitable procurement of reactive power is considered. In the proposed real-time market, the participants submit their offer to system operator and the best combination of participants for procuring of required reactive power are selected. The IEEE 39-bus network is used to illustrate how the proposed method has efficient role in minimizing the cost of reactive power procurement and maximizing the social welfare and distance to voltage stability margins.
