“…In recent years, most studies [4], [7], [16]- [22] have focused on exploiting the damping capability of wind farms or PV systems owing to the high cost involved in installing FACTS, the displacement of conventional generators with renewable resources, and the need to provide ancillary services via converter-based resources demanded by transmission operators. The damping contribution from largescale wind/PV systems can be achieved by modulating active power [21], reactive power/voltage [7], [16], [17], or dualcontrol loops [4], [19], [20]. In this context, some researchers aimed primarily at highlighting the effectiveness of active/reactive power coordination or presenting a novel active power modulation strategy for utility-scale wind and/or PV systems [4], [20], [21].…”

“…Subsequently, in such situations, low-frequency oscillations (LFOs) will be of great concern since poor damping of these modes could threaten the stability of the large interconnected system [5], [6]. Hence, investigating the small-signal stability of WPTBS under uncertain operating conditions and suppressing LFOs is crucial to sustaining the satisfactory dynamic performance of the system undergoing disturbance [7]. Installing a wide-area damping controller (WADC) in this respect provides a frequently adopted solution to maintain the system's sufficient damping performance [8].…”

The wind-photovoltaic-thermal-bundled power system (WPTBS) comes with a wide range of potential grid applications and provides an efficient way to export bulk amount of power under high intermittency of wind and photovoltaic (PV) resources. This increasing penetration alongside distant power transmission, however, may cause detrimental impacts on low-frequency oscillations (LFOs), eventually threatening the stability of WPTBS. In this prospect, installing a wide-area damping controller (WADC) is proven to be efficient in suppressing LFOs but the uncertainty related to varying operating points, the time delay involved in transmitting a wide-area signal, and the possibility of remote signal disconnection may compromise the damping capability of a WADC. Following that, the proposed study presents a reduced-order robust wide-area damping controller (RWDC), injected into the wind turbine system, to stabilize the LFOs in the WPTBS while accounting for operational uncertainties, time delays, and communication failure. At first, the uncertainties are characterized in the form of polytope vertices, where each vertex represents a linearized model corresponding to a distinct operating condition. A two-stage linear matrix inequality (LMI) approach is then adopted to determine the design parameters of reduced-order RWDC, which simultaneously stabilizes the entire uncertain model by minimizing the 𝐻 ∞ norm and ensures closed-loop stability via parameter-dependent Lyapunov functions. Finally, using small-signal analysis and extensive simulation results, the effectiveness of the controller is confirmed under different operating scenarios, including critical and unstable oscillation conditions, followed by a comparison with existing methods.

“…In [24], the authors demonstrated the most effective tuning method for a unified power flow controller to reduce interarea oscillations in a multi-machine system using the firefly method. In [25], the authors described a STATCOM controller design that dampens low-frequency oscillations in the power system using a modified shuffling frog leaping algorithm. The positioning and application of STATCOM storage for the enhancement of the voltage stability of power systems integrated with wind farms were detailed by the authors of [26].…”

In the field of electrical engineering, there is an increasing concern among managers and operators about the secure and cost-efficient operation of smart power systems in response to disturbances caused by physical cyber attacks and natural disasters. This paper introduces an innovative framework for the hybrid, coordinated control of Unified Power Flow Controllers (UPFCs) and Power System Stabilizers (PSSs) within a power system. The primary objective of this framework is to enhance the system’s security metrics, including stability and resilience, while also considering the operational costs associated with defending against cyber-physical attacks. The main novelty of this paper lies in the introduction of a real-time online framework that optimally coordinates a power system stabilizer, power oscillation damper, and unified power flow controller to enhance the power system’s resilience against transient disturbances caused by cyber-physical attacks. The proposed approach considers technical performance indicators of power systems, such as voltage fluctuations and losses, in addition to economic objectives, when determining the optimal dynamic coordination of UPFCs and PSSs—aspects that have been neglected in previous modern research. To address the optimization problem, a novel multi-objective search algorithm inspired by Harris hawks, known as the Multi-Objective Harris Hawks (MOHH) algorithm, was developed. This algorithm is crucial in identifying the optimal controller coefficient settings. The proposed methodology was tested using standard IEEE9-bus and IEEE39-bus test systems. Simulation results demonstrate the effectiveness and efficiency of this approach in achieving optimal system recovery, both technically and economically, in the face of cyber-physical attacks.

“…So far, several methods have been offered for the coordinated regulation of PSS and FACTS devices' parameters, most of which are based on parametric optimization models [19,20]. These models include the transient state model [21] and the closed-loop residuals model [22], which employ different gradient-based non-linear optimization methods to solve the optimization problem. These methods are computationally fast but have problems finding the general system optima point or starting points.…”

Power system stability is of paramount importance in the context of energy sustainability. The reliable and efficient operation of power systems is crucial for supporting modern societies, economies, and the growing demand for electricity while minimizing environmental impact and increasing sustainability. Due to the insufficient effect of power system stabilizers (PSSs) on damping the inter-area mode oscillations, Flexible AC Transmission System (FACTS) devices are utilized for damping this mode and stabilizing power systems. In the present study, a novel optimization framework considering different and variable weight coefficients based on eigenvalue locations is presented, and the parameters of PSS and variable impedance devices, including static Volt-Ampere Reactive (VAR) compensator (SVC) and Thyristor-Controlled Series Compensator (TCSC) (comprising amplifying gain factor and time constants of phase-compensating blocks), are optimized in a coordinated manner using the proposed optimization framework built based on genetic algorithm (GA). Moreover, in the suggested optimization framework, the locations of FACTS devices and control signals are considered optimization parameters. Numerical results for the IEEE 69-bus power system demonstrated an effective improvement in the damping of inter-area modes utilizing the offered approach.
