“…In designing damping controller, the feedback signals could either comprise wide-area information through utilization of PMUs dispersed over the network or be limited to merely local data captured at the line's sending end. Since this paper concentrates on the inter-area phenomenon on which is inherently a global issue, wide area signals are used for the damping controller input signal [16]- [17]. To optimize the parameters of the designed Wide Area Damping Controller (WADC) the Particle Swarm Optimization (PSO) method is utilized.…”

FACTS devices are one of the latest technologies which have been used to improve power system dynamic and stability during recent years. However, widespread adoption of this technology has been hampered by high cost and reliability concerns. In this paper an economical phase imbalanced shunt reactive compensation concept has been introduced and its ability for power system dynamic enhancement and inter-area oscillation damping are investigated. A hybrid phase imbalanced scheme is a shunt capacitive compensation scheme, where two phases are compensated by fixed shunt capacitor (C) and the third phase is compensated by a Static Synchronous Compensator (STATCOM) in shunt with a fixed capacitor (CC). The power system dynamic stability enhancement would be achieved by adding a conventional Wide Area Damping Controller (WADC) to the main control loop of the single phase STATCOM. Two different control methodologies are proposed: a non-optimized conventional damping controller and a conventional damping controller with optomised parameters that are added to the main control loop of the unbalanced compensator in order to damp the inter area oscillations. The proposed arrangement would, certainly, be economically attractive when compared with a full three-phase STATCOM. The proposed scheme is prosperously applied in a 13-bus six-machine test system and various case studies are conducted to demonstrate its ability in damping inter-area oscillations and power system dynamic enhancement.

“…Because time delays bring about a phase lag which can affect the control performance and interactions among system dynamics, it must be considered in the model design process. Several studies have considered time delay in control design using different algorithms [35], [39], [42], [43]. In WAMS, the important delay period is between the measurement and the controller input signal arrival, which is around 0.5-1.0 s [42].…”

Power system oscillation damping remains as one of the major concerns for secure and reliable operation of large power systems, and is of great current interest to both industry and academia. The principal reason for this is that the inception of poorly-damped low-frequency inter-area oscillations (LFIOs) when power systems are operating under stringent conditions may lead to systemwide breakups or considerably reduce the power transfers over critical corridors. With the availability of high-sampling rate phasor measurement units (PMUs), there is an increasing interest for effectively exploiting conventional damping control devices, such as power system stabilizers (PSSs), by using these measurements as control input signals. In this paper, we provide a comprehensive overview of distinct elements (or "building blocks") necessary for wide-area power system damping using synchrophasors and PSSs. These building blocks together shape a tentative methodical framework, and are disposed as follows: (1) fundamental understanding of the main characteristics of inter-area oscillations, (2) wide-area measurement and control systems (WAMS and WACS) and wide-area damping control (WADC), (3) advanced signal processing techniques for mode property identification, (4) methods for model-based small-signal analysis, (5) control input signals selection, and (6) methods for PSS control design. We also describe the latest developments in the implementation of synchrophasor measurements in WAMS and WACS as well as their prospectives for WADC applications. This paper serves both to abridge the state-of-the-art in each of these elements, and to accentuate aspiring ideas in each building block.

“…In [8], a damping control approach for sub-synchronous resonance with Static Synchronous Series Compensator (SSSC) has been addressed and in [9] the capability of Type-2 wind turbines to damp SSR IJPEDS ISSN: 2088-8694  occurring in close synchronous generators connected to the grid by means of series-compensated transmission lines has been investigated. In the literature, it is demonstrated that if remote signals are fed to the damping controllers, the system dynamic performance can be enhanced compared with the locally measured signals [10]. The widearea measurement system (WAMS), enabled by broad deployment of phasor measurement units (PMUs), is capable to monitor dynamic data of the power system such as voltage, current, angle, and frequency.…”

Recent technological progresses in the wide-area measurement systems (WAMS) are realizing the centralized controls as a breakthrough for improving the power systems stability. The most challenging deficiency against WAMS technology is related to communication delays. If this latency is neglected, it can deteriorate the damping performance of closed loop control or even degrade the system stability. This paper investigates a conventional Wide Area Damping Controller (WADC) for a static synchronous series compensator (SSSC) to damp out the Sub-Synchronous Resonance (SSR) and also investigation of the destructive effect of time delay in remote feedback signal. A new optimization algorithm called teaching-learning-based-optimization (TLBO) algorithm has been implemented to normalize and optimize the parameters of the global SSR damping controller. The IEEE Second Benchmark Model is considered as the system under study and all simulations are carried out in MATLAB/SIMULINK environment.
