“…On the other hand, if the positive-GTO (GTO1) and the negative-GTO (GTO2) turn off once per cycle, at a given angle γ counted from the zero-crossing of the line current, the main capacitor C charges and discharges with alternate polarity (Zhang, X.P. et al, 2006), (De Jesus F. D. et al, 2007). Hence, a voltage VC appears in series with the transmission line, which has a controllable fundamental component that is orthogonal (lagging) to the line current.…”

“…However, if a power system planner were to install a TCSC while considering lines 1-5, qualitative constraints could, in fact, still arise, such as the securing of the site, operational problems, and facility coordination. In addition, dynamic constraint could, such as the SSR phenomenon that may occur when a steam turbine-generator is connected to a long transmission line with series compensation [17]. For this reason, in this study, optimal candidate locations are considered to be those locations that have a positive value of power loss sensitivity α .…”

-Flexible AC Transmission System (FACTS) application study on enhancing the flexibility of AC power system has continued to make progress. A thyristor-controlled series capacitor (TCSC) is a useful FACTS device that can control the power flow by adjusting line impedances and minimize the loss of power flow and voltage drop in a transmission system by adjusting line impedances. Reduced power flow loss leads to increased loadability, low system loss, and improved stability of the power system. This study proposes the optimal location and compensation rate method for TCSCs, by considering both the power system loss and voltage drop of transmission systems. The proposed method applies a multi-objective function consisting of a minimizing function for power flow loss and voltage drop. The effectiveness of the proposed method is demonstrated using IEEE 14-and a 30-bus system.

Abstract. To increase transmitted power, series capacitors may be used in the transmission lines. A compensated transmission line together with a turbine-generator may cause Sub-Synchronous Resonance (SSR) phenomena in a power system. In this paper, details of dynamic modeling of a single machine power system connected to the network through a transmission line, compensated with a series capacitor, have been presented. Static Synchronous Series Compensator (SSSC) as one of series FACTS devices has been used for the damping of the SSR oscillations. For this purpose, a linear damping SSSCbased stabilizer with lead-lag structure is incorporated into SSSC controller. To determine parameters of SSSC stabilizer, a new multi-objective function has been proposed. In this function, in addition to improving stability of critical modes, the gain of the stabilizer has been considered. To have a stabilizer with a minimum-phase structure, suitable constraints have been determined and added to the objective function. To optimize the objective function, a recently developed optimization technique known as Grey Wolf Optimization (GWO) algorithm has been applied. The eigenvalues analysis and nonlinear simulations of the IEEE First Benchmark Model (FBM) power system with a SSSC stabilizer illustrate the e ectiveness of the proposed method in suppressing SSR oscillations in the studied system.
