“…Other feedback signal selection methods are also proposed based on geometric measures of modal controllability/observability (GMCO), the minimum singular value (MSV), and the Hankel singular value (HSV) in [13][14][15]. Nguyen-Duc et al [16] have proposed a hybrid method of wide-area signal selection based on GMCO, loop to mode measures and phase compensation conflict. However, all these control signal selection methods are based on the nominal operating condition and the controller is intended to obtain the required damping performance under the worst case operating scenario.…”

In this study, norm bounded linear quadratic Gaussian controller synthesis method is utilised to design a wide-area measurement signal (WAMS)-based power oscillation damping controller at photovoltaics (PV) plants. The uncertainties associated with the system are confined by the system matrices which are the affine functions of parameters belong to a convex polytopic region. A hybrid method based on Hankel singular value (HSV) and right-half-plane zeros (RHP-zeros) is utilised to assess and select the optimal feedback signal for the PV wide-area damping controller. First, the HSVs of the delayed subsystems are employed to preselect the candidate signals for damping the target mode. Then, the RHP-zeros and the modal interaction measures of the candidate signals are evaluated. Finally, the signal with minimum variance in HSV and modal interaction over the wide range of operating conditions is selected as the optimal feedback signal for the controller design. The wide range of operating conditions is obtained by the probabilistic distribution of loads, synchronous generators and PVs. The approach has been tested on a large 16 machine, 68 bus test system as compared to geometric measures of controllability/observability method and has shown improved performance.

In this paper, an ADMM based novel distributed wide-area control architecture is proposed for damping the interarea oscillations. In this approach, first, an interconnected power system is divided into areas based on coherency grouping. Second, local processors are assigned on each area that estimates a blackbox transfer function model based on Lagrange multipliers using measurements. These local area processors are then used to estimate a global transfer function model of the power system based on a consensus algorithm through a global processor. After convergence, a transfer function residue corresponding to the inter-area mode of interest is derived, to determine optimal wide area control loop. Finally, a wide-area damping controller is designed based on this information. The efficacy of the controller is validated using two area and IEEE-39 bus test systems on RTDS/RSCAD and MATLAB co-simulation platform.

“…In the last decade, different working groups have demonstrated the effectiveness of using wide-area signals and modern control techniques to deal with small-signal stability problems in energy systems, see Werner et al (2003);Nguyen-Duc et al (2010); Li et al (2012); Mokhtari et al (2013); Chaudhuri et al (2010); Zhang and Bose (2008); Zima et al (2005); Korba et al (2007). Their work have concentrated on different aspects such as dealing with time delays Chaudhuri et al (2004) in the feedback signals, adaptive features Korba et al (2007), providing a low order controller Simfukwe et al (2012) and the type of actuator used by the controller (FACTS/HVDC etc.)…”
