Congestion management of system by optimal placement of TCSC inacontingency condition

Department of Electrical Engineering, National Institute of Technology Durgapur, Durgapur-713 209, West Bengal, India E-mail: ashish.singh.nitdgp@gmail.com, aashishkumar.bohre@ee.nitdgp.ac.in Manuscript received online 14 June 2020, revised and accepted 26 August 2020 With the restructuring in the Indian Power Sector, the power sector management have been going through major transformation in the generation, transmission and distribution areas. To meet the load demand it’s still a huge challenges. Due to contingency line constraints are violated, which leads to congestion, thus threatening the overall security of the interconnected system. TCSC is used to relieve the congestion in the system. In this paper, TCSC placement in an N-1 Contingency case is located through the PSO by forming the weighting function considering system index in a 6-bus system and 14 bus system using MATPOWER tool
