“…The configuration of the TCSC-WADC system shown in Fig.1 is constructed to damp the inter-area oscillation for an interconnected power system with signal delay. The parameters of the controller can be designed using Theorem 1 and changed into the nonlinear optimization problem (14). Then, the design process of WADC is given as follows:…”

A new wide-area damping control strategy is investigated for flexible AC transmission systems (FACTS) device using widearea measurement system (WAMS) signals. The purpose is to design a dynamic output wide-area damping controller (WADC) for improving the stability of interconnected power systems. The time-varying delay of wide-area signal is incorporated into the design process, which can effectively reduce the delay effect on the damping performance. First, a discrete-time plant model with time-varying delay is established for power systems; then by using the proposed improved free-weighting matrices (IFWMs) approach and a convex optimization algorithm, a new and less conservative delay-dependent stability criterion, expressed in the terms of linear matrix inequalities (LMIs), is obtained without ignoring any useful terms on the difference of a Lyapunov function. Detailed case studies on a 4-machine two-area benchmark test system and 16-machine five-area NETS-NYPS interconnected system show that the designed WADC can not only maintain effective damping performance under the condition of time-varying delay but also get the maximum wide-area time delay.

“…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.

“…The optimal design problem of damping controllers is a complex optimization problem with the presence of multiple local minima. Hence, extensive studies have been carried out to utilize different optimization techniques for the solution, ranging from gradient based local search algorithms [1] to derivative free global optimization methods [2][3][4][5]. The gradient-based algorithms converge quicker by applying derivative information to recognize an excellent search direction, and they can achieve solutions with higher accuracy compared to global optimization techniques.…”

A novel optimization algorithm by combining the artificial bee colony (ABC) algorithm and the sequential quadratic programming (SQP), that is the gradient based ABC algorithm, is presented to resolve the problems of global optimization and inter-area oscillations damping in power system. The proposed algorithm merges the global exploration ability of the artificial bee colony to converge quickly to a near optimum resolution, and the correct local exploitation capacity of the sequential quadratic programming to accelerate the search process and discover a correct solution. To show the feasibility and efficiency of the new method, numerical result is investigated on the New England system by tuning a power system stabilizer and a controller for the static VAR compensator. The proposed gradient based ABC algorithm is compared with ABC. The simulations studies demonstrate that the proposed algorithm based designed damping controllers perform better than controller designed by ABC.
