“…Developing a decentralized/hierarchical control approach with significant advantages of reliability and flexibility for inter-area oscillatory modes was among the pioneers [411]. Improving power system dynamic performance was also testified by means of WAMS-based controllers of automatic voltage regulators (AVRs) [107], [412], power system stabilizers (PSSs) [413], high-voltage DC (HVDC) transmission lines [414]- [417] FACTS devices [418]- [424], energy storage devices [413], [417], [423], [424], variablespeed wind farms [425], or doubly-fed induction generator (DFIG) wind farms [426]. Some research efforts were dedicated for designing control systems compensating for the communication limited bandwidth and latencies in feedback and command signals [415], [422], [427]- [435].…”

Phasor measurement units (PMUs) are rapidly being deployed in electric power networks across the globe. Wide-area measurement system (WAMS), which builds upon PMUs and fast communication links, is consequently emerging as an advanced monitoring and control infrastructure. Rapid adaptation of such devices and technologies has led the researchers to investigate multitude of challenges and pursue opportunities in synchrophasor measurement technology, PMU structural design, PMU placement, miscellaneous applications of PMU from local perspectives, and various WAMS functionalities from the system perspective. Relevant research articles appeared in the IEEE and IET publications from 1983 through 2014 are rigorously surveyed in this paper to represent a panorama of research progress lines. This bibliography will aid academic researchers and practicing engineers in adopting appropriate topics and will stimulate utilities toward development and implementation of software packages.INDEX TERMS Phasor measurement unit (PMU), synchrophasor measurement technology (SMT), wide-area measurement system (WAMS).

“…Finally, the last islanding part in Step 5 is devoted to present how to split tie‐lines as a consecutive splitting strategy. In this step, three main approaches as CART technique [29], system oscillatory pattern [30] and C5.0 decision tree technique [31] are presented which concentrated to provide proper islanding strategies to split the power system through stable islands.…”

This paper presents an online protective scheme of estimating critical inter‐area angle for controlling the inter‐area oscillations based on evaluating the rate of changes of rotor angle oscillations as an adaptive tripping index (ATI)‐based protective zone. For this purpose, by using wide area measuring system technology, oscillatory signals Δδ and Δω are measured which based on correlation coefficients criteria, coherent groups are identified which based on evaluating oscillating areas, inter‐area signals ΔδCOI‐AB and ΔωCOI‐AB are provided. In the case of evaluating an inter‐area oscillation, the proposed ATI scheme is activated which the first zero crossing point (ZCP0) of δCOI‐AB is determined as the critical criteria for estimating unstable situation. The proposed ATI approach consists of two adaptive protective zones ATI1 and ATI2 to estimate inter‐area oscillatory and inter‐area transient instabilities, respectively. The proposed ATI is an online and non‐model‐based scheme which evaluates the system dynamic stability through two straight and sinusoidal‐based adaptive zones. The effectiveness of the proposed ATI approach is evaluated on three different test systems IEEE 39‐bus, modified IEEE 39‐bus with converter‐based low inertia sources and a practical Iran nation power grid with presenting positive effects of damping inter‐area oscillations through different operational and topological conditions.

“…With large disturbance, the system operates in an undesirable condition and it may not perform as it is designed to. Besides, non‐linear control, such as variable structure control [2], adaptive control [3, 4], the Hamiltonian method [5], inverse system method [6], H‐infinity control [7] and so on, may perform well in many conditions. However, they need control laws and large amounts of online calculation which make them not so practical.…”

To improve the performance of the governing system as well as the stability of the power system, the authors propose grey prediction extension control (GPEC) in the design of generator governing system. Comparing with the conventional control strategy such as conventional proportional–integral–derivative control and simple extension control, GPEC is more suitable for the complex, huge‐dimension and time‐varying modern power systems. Both a simple hydropower system and a typical multi‐machine system are studied, respectively. The simulation results indicate that the proposed GPEC governor controller performs better in reducing overshoot and adjusting time with superiority in leading the system into a stable state.
