“…The CHIL tests allowed the efficient tuning of the SVC controller, as well as effective fault tracing. A wide-area control of a STATCOM using a hybrid CHIL and software-in-the loop configuration was validated in [107]. The transient stability enhancement using a wide-area controlled SVC was investigated in a CHIL configuration [54].…”

The role of flexible alternating current transmission systems (FACTSs) in the provision of grid services is becoming increasingly important, due to the massive integration of intermittent renewable energy sources, energy storage systems, and the decommissioning of thermal plants. A comprehensive literature review of grid services offered by FACTS is performed, focusing on the different grid services that they can provide, such as power flow control, reactive power control, voltage control, power quality improvement, harmonic mitigation, improvement of transient stability, and damping of inter-area and intra-area oscillations. These grid services need to be realistically and economically validated in suitable testing environments. A review of relevant standards, guides, and the literature is performed, which covers the entire range from functional specification and factory testing up to the field testing of FACTS. Advanced industry practices, such as controller hardware in the loop (CHIL) testing of FACTS controllers by the manufacturer, and recent trends, such as CHIL testing of replica controllers by the owner, are underlined. Limitations of conventional testing and CHIL testing are explained and the use of power hardware in the loop (PHIL) simulation for FACTS testing is discussed. CHIL and scaled-down PHIL tests on a transmission static synchronous compensator (STATCOM) are performed and a comparison of the results is presented.

“…One successful method for thorough testing requires a laboratory testbed consisting communication-enabled "realtime-simulator" which may be coupled with hardware-inloop (HIL), software-in-loop (SIL), power HIL (PHIL), and control HIL (CHIL) setup [11][12][13][14][15]. In [15], a synchrophasorbased voltage stability monitoring application was tested with (1) positive-sequence based (PSB) simulations, (2) PMU data from real-time-HIL, and (3) PMU data from a real Nordic grid transmission system, sequentially.…”

This article presents a study on real-time testing of synchrophasor-based “wide-area monitoring system’s applications (WAMS application).” Considering the growing demand of real-time testing of “wide-area monitoring, protection, and control (WAMPAC)” applications, a systematic real-time testing methodology is formulated and delineated in diagrams. The diagrams propose several stages through which an application needs to be assessed (sequentially) for its acceptance prior to implementation into a production system. However, only one stage is demonstrated in this article which comprises the use of a prototyping software toolchain and whose potential is assessed as sufficient for preliminary real-time testing (PRTT) of WAMS applications. The software toolchain is composed of two components: the MATLAB software for application prototyping and other open-source software that allows ingesting prerecorded phasor measurement unit (PMU) signals. With this software toolchain, a PRTT study is presented for two WAMS applications: “testing of the PMU/phasor data concentrator (PDC)” and “testing of wide-area forced oscillation (FO) monitoring application.”

“…However, the problems related to the selection of optimal control loop are not addressed here. The use of PMU data for wide-area control of static synchronous compensator is discussed in [18], but the effect of mutual coupling during mode estimation and optimal signal selection is not represented. A power system model using MIMO identification based on auto-regressive moving average exogenous methodology is developed in [19], but an optimal method for signal selection is not addressed.…”

Interconnected power grid exhibits oscillatory response after a disturbance in the system. One such type of oscillations, the interarea oscillations has the oscillation frequency in the range of 0.1 to 1 Hz. The damping of inter-area oscillations is difficult with local controllers, but it can be achieved using a Wide Area Damping Controller (WADC). For effective control, the input to the WADC should be the most observable signal and the WADC output should be sent to the most controllable generator. This paper presents a measurement-based novel algorithm for multi-input-multi-output (MIMO) transfer function identification of the power system based on optimization to estimate such oscillation frequencies. Based on the MIMO transfer function the optimal control loop for WADC is estimated. The WADC design is based on the discrete linear quadratic regulator (DLQR) and Kalman filtering for damping of inter-area oscillations. Since the MIMO identification is based on actual measurements, the proposed method can accurately monitor changes in the power grid whereas the conventional methods are based on small-signal analysis of a linearized model which does not consider changing operating conditions. The overall algorithm is implemented and validated on a RTDS/RSCAD R and MATLAB R real-time co-simulation platform using two-area and IEEE 39 bus power system models.
