Abstract

An optimal power flow model is developed and analyzed with TCSC (Thyristor Controlled Series Compensator) for practical power networks using Newton’s optimization technique. The optimal generation schedules and corresponding transmission losses along with optimal TCSC setting parameters for different case studies are also reported. The performance of the proposed algorithm is tested for both IEEE-30 and IEEE-118 bus systems with multiple TCSC devices. Convergence of the proposed model is independent of number and initial condition of TCSCs. The authors also observe that the proposed algorithm can be applied to larger systems and does not suffer from computational difficulties.
