“…The SG -TCSC system and SG -SVC system models adopted in this work have been previously presented in [20] and [21] , respectively, where individual elements of the frequency domain models as a function of system parameters are explicitly provided. To avoid an unnecessary duplication of work, the deduction of these models is not included here and only reference to them is made in Section 2 for completeness.…”

“…The individual elements of the transfer function matrices are only calculated for specific operating conditions, but these are provided as supplementary content for the interested reader. In addition, reference [4] builds on [21] by including a damping control loop to the SG -SVC system. In [4] , the damping capabilities of the SVC are compared to those achieved by a power system stabiliser (PSS), which is a local device installed at the terminals of a synchronous machine.…”

“…Although the synchronous generator -SVC system presented in [4] is used in this paper, the emphasis here is placed on how the abilities of an SVC, a shunt-connected power electronics-based device, measure against those provided by a TCSC, a power-electronics based device connected in series, to ameliorate the switch-back characteristic introduced by SGs. Given that ICAD represents an analysis and control system design framework yet to be consolidated in power systems applications, the scope has been restricted to single-machine infinite bus systems.…”

a b s t r a c tA comparison of the capabilities of two quite distinct power electronics-based 'flexible AC transmission systems' devices is presented. In particular, the damping of low frequency electromechanical oscillations is investigated aiming at improving the performance of power systems. The comparison is made using frequency domain methods under the 'individual channel analysis and design' framework. A synchronous generator feeding into a system with large inertia is used for such a purpose. Two system configurations including compensation are analysed: (a) in series in the form of a thyristor-controlled series compensator, and (b) in shunt through a static VAr compensator featuring a damping controller. Analyses are carried out to elucidate the dynamic behaviour of the synchronous generator in the presence of the power electronics-based controllers and for the case when no controller is present. Performance and robustness assessments are given particular emphasis. The crux of the matter is the comparison between the abilities of the static VAr compensator and the thyristor-controlled series compensator to eliminate the problematic switch-back characteristic intrinsic to synchronous generator operation by using the physical insight afforded by 'individual channel analysis and design'.
