An effective approach for ATC enhancement with FACTS device - A case study

This paper presents an acceptable solution for Available Transfer Capability (ATC) enhancement. This has been accomplished with Static Synchronous Series Compensation (SSSC) and Unified Power Flow Controller (UPFC). The optimal usage of SSSC and UPFC leads to maximization of Total Transfer Capability (TTC). To illustrate the applicability of proposed approach and gain confidence, a case study has been done on a modified IEEE 30 bus system divided into two areas with eight interconnecting transmission lines using PSAT (Power System Analysis Tool Box) software. Calculations of ATC have been done with PSAT. The results demonstrate the capability of approach in ATC enhancement which may form a basis for existing transmission lines upgradation.
