The main reasons to use gate-controlled series capacitor (GCSC) as new controlled series compensators are to enhance power transfer capacity and improve transient stability by mitigating sub-synchronous resonance (SSR) and damping power oscillations [27 – 29].
The series capacitor is used in long transmission lines in order to compensate the line reactance, decrease voltage drop and control the line flow. However, a constant capacitor arises practical problems such as SSR.
Other applications include series power filters and large motor soft starting schemes. Hybrid use of series and shunt switched capacitors are now used in renewable energy converter DC–AC and AC–DC interface systems for energy efficient operation, voltage stabilisation and power quality enhancement.
A review of shunt capacitors can be an extension of current work. Series-capacitor compensation is emerging as a stabilising tool in series compensation and phase shifting FACTS devices. Other applications include series power filters and large motor soft starting schemes.
Therefore, the GCSC shows a capacitor behaviour, as expected. From (34) and (35), the GCSC modifies the effective capacitor from to , determining the resonance. Compared to a constant capacitor, the GCSC changes the resonance frequency to mitigate SSR oscillations.
Future applications are now extended to GTO-based series capacitor banks in distribution/utilisation grid systems for energy efficient and loss reduction for nonlinear-inrush type, cyclical and temporal loads [35, 58, 59].
