Placement of shunt FACTS Devices for maximum power transfer capability in a Series Compensated LT Line

Maximum power transfer capability in the transmission line is the utmost important consideration in power systems. VAR Compensator (SVC) and Static Synchronous Compensator (STATCOM) are important devices in FACTS family, and is widely recognized as an effective and economical means to solve the power system stability problem. SVC and STATCOM are used as shunt in transmission system. In the present work a series compensated long transmission line with a shunt FACTS device considered for the optimal location of the shunt FACTS devices to get the highest possible benefits of maximum power transfer and system stability. The Effect of degree of change in series compensation on the optimal location of the shunt Facts devices in terms of power transfer capability and stability of the system. This paper presents a two stage approach, a conventional method is used to determine the optimal location of shunt facts device in a series compensated line and then fuzzy logic is used to determine the optimal placement. The proposed method is considered for 13.8KV Base, 6*350 MVA and 450 km long transmission line. All the simulations for the above work have been carried out using MATLAB /SIMULINK software.
