“…The SVC damping loop does not alter the internal coupling since its direct impact is not on the speed or terminal voltage channels, as shown by its MSF 2 ( s ). 2 ( s ) corresponding to the TCSC shows a reduced coupling due to a decreasing electrical distance of the transmission line. The peak moves on to higher frequencies but it is still pronounced.…”

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'.

Summary Unified power flow controller (UPFC) is utilized to regulate the bus voltage as well as the power flow through a power system. A solution of optimal power flow (OPF) problems with UPFC is a crucial and complex task due to the required modifications for considering the parameters of UPFC. This work proposes a simplified UPFC modeling into an OPF code in order to avoid the programming complexity. Moreover, the solution of an OPF problem with a UPFC model is obtained by a recent physical‐based optimization technique called lightning attachment procedure optimization (LAPO). Different objective functions including minimizing fuel cost and fuel cost with valve point effect (VPE), reduction of emission, improvement of voltage profile, and improving the voltage stability index are considered. The proposed algorithm is tested using the standard IEEE 30‐bus system. The results obtained by the proposed algorithm are compared with those obtained by other optimization techniques. However, the obtained results verify the applicability of the simplified UPFC model in OPF.

Summary In this paper, a tuning approach for HVDC control technology based on virtual synchronous power (VSP) concept is developed and reflected in an extended multiarea automatic generation control (AGC) system including renewable energy sources (RES). A novel, nature‐inspired algorithm named adaptive mixed grey wolf (amixed GWO), which combines two improved versions of GWO, was recently proposed in order to effectively handle a problem with both discrete and continuous variables. This algorithm was first applied to optimize the VSP‐based controller parameters based on integral square error (ISE). The performance of the proposed algorithm has been compared with FMINCON's interior‐point algorithm to demonstrate its positive effects on the system stability. For better dynamic performances, a new optimization approach based on eigenvalues sensitivity analysis was proposed for the purpose of achieving optimal VSP control variables tuning for different power system structures. Simulation tests were performed to show the higher level of stability performance achieved by the proposed approach compared to the one based on ISE. Simulation results also revealed that the amixed GWO technique has better tuning capability in comparison with the other applied GWO versions.
