“…The coordinated control generates through remote signals a control signal for each device in order to achieve the control objective. Contribution [16] implements a coordinated control with a SVC and a power system stabilizer (PSS). In addition, it analyzes the effects of time delays on the proposed control.…”

Wide area monitoring systems (WAMS) together with phasor measurement units (PMUs) are the key to implement wide area control systems (WACS). WACS are responsible of achieving different control objectives from signals and measurements taken of a wide area network. Control objectives can be focused on a large region of the network or part of it. Furthermore, flexible ac transmission systems (FACTS) are devices that allow to implement the control laws designed and developed from measurements of WAMS/PMU. This paper presents a review of the current state of the art of WACS incorporating FACTS devices, specifically, the different FACTS configurations, applications and control used.Index Terms-Wide area control systems, wide area monitoring systems, flexible ac transmission systems, power system control, phasor measurement unit.

“…In [19] a methodology to compensate the data dropout is presented, based on the Observer-driven Reduced Copy (ORC) approach in order to improve the performance of the wide area controller. Furthermore, in [20] a Smith predictor was utilized to preserve the performance of the controller within specific limits during large delays. Nevertheless, the majority of the published papers on this matter either utilize a simplified expression of the measurement errors or they do not consider them at all.…”

Wide Area Control (WAC) of power systems is highly depended on synchronized measurements provided by the Phasor Measurement Units (PMUs). However, the contemporary measurement chain and the communication network are far from ideal. Therefore, it is essential to identify the impact of the availability and quality of the synchronized measurements, on the wide area controller's performance. This paper examines the effect of measurement errors and delays/dropouts on the damping capability of the wide area controller. The measurement errors considered in this work are according to the dynamic compliance requirements of the PMU during disturbances as it is imposed in the IEEE Synchrophasor Standard C37.118.1-2011. The delays are separated into measurement and feedback delays. The results indicate that delays along with dropouts deteriorate significantly the WAC performance, while the consideration of only the measurement errors (steady-state and dynamic) in the simulation environment has a minor effect on its operation. For this reason, a linear predictor is proposed to compensate effectively and timely all the system's delays. The case studies are conducted on the IEEE 39-bus system and evaluated through the Prony analysis tool.

“…The studies in [8] and [9] employ classical H ∞ methods to deal with fixed delays, and [10] suggests a parameterdependent H ∞ gain-scheduling for delays within a certain tolerance. Other approaches in the literature consider a use of Smith predictors [11], adaptive control schemes [12] and lead-lag compensators [13]. Nonetheless, all aforementioned studies focus on conventional power systems and the underlying delays in wide-area measurements.…”

This paper deals with the converter control design under time delay uncertainty in power systems with high share of converter-based generation. Two approaches for time delay modeling are proposed using linear fractional transformations and linear parameter-varying systems, respectively. Subsequently, two output-feedback synthesis methods are implemented based on H∞ control theory, and formulated using linear matrix inequalities: (i) a norm-bounded parametric H∞ controller; and (ii) a gain-scheduled H∞ control. These robust control principles are then employed to improve the performance of Voltage Source Converters (VSCs) under varying measurement delays. Three novel control strategies are proposed in order to redesign the conventional inner control loop and improve converter performance when dealing with measurement uncertainty. Finally, the controllers are integrated into a state-of-the-art VSC model and compared using time-domain simulations.
