This project presents a new concept of using the solar farm has a STATCOM in increasing the power transmittable limits of a transmission system. By the voltage regulation the available power transmit limits can be increased. This is performed by using entire rating of the solar inverter which is suspended0during night time and the left over real power after the real power generation during the day time. The single machine infinte0bus system is used for the transient studies where the PV farm is located at the midpoint. The transient studies are performed using MATLAB software. The controller is designed to maintain the Vpcc at 1pu and the post fault clearance settling time of the oscillations to come within05% of its steady state value. The PV STATCOM can be used to increase the power transfer capability otherwise it requires a shunt or series capacitors or the other FACTS devices which are0expensive.
