Power Flow Control and Transmission Loss Minimization model with TCSC and SVC for Improving System Stability and Security

In general, the problem of reactive power compensation is viewed from two aspects: load compensation and voltage support. Voltage support is generally required to reduce voltage fluctuation at a given terminal of a transmission line. Optimal power flow (OPF) model has been developed and analyzed with Thyristor Controlled Series Compensator (TCSC) and Static var compensator (SVC) for practical power networks using Newton's optimization technique. The optimal transmission losses and corresponding generation schedules with optimal TCSC and SVC setting parameters for different case studies have also been reported. The performance of the proposed algorithm has been tested for IEEE-30 Bus system with single and multiple TCSC& SVC devices with contingency analysis and do not suffer with Computational difficulties.
