“…From the 65 works reviewed, most of them present strategies to damp inter-area oscillations or to improve rotorangle stability. Specifically, 16 papers address inter-area oscillations [78], [81], [115], [122], [125], [130], [151], [179], [182], [193], [199], [227], [236], [238], [241], [248] and 15 papers address rotor-angle stability [137], [139], [161], [166], [180], [204], [206], [207], [210], [213], [216], [218], [219], [231], [233]. From the remaining 34 papers, 7 address frequency stability issues [127], [146], [150], [168], [235], [237], [257] and 10 papers address voltage stability [55], [149], [152], [184], [191], [194], [201], [244],…”

“…This approximation reduces a time-delayed system to one with a rational transfer function, thus allowing its use for stability analysis and design of controllers for delayed systems [265]. Most strategies rely on low-order Padé approximations [61], [67], [78], [119], [131], [145], [157], [186], [193], [199], [200], where first-order approximations are developed. Second-order approximations are considered in [73], [108], [123], [134], [135], [156], [169], [185], where [169] refers to a particularly modified second-order approximation.…”

“…This aspect is addressed in [61], [150], [214]. In [199], a centralized controller utilizes superconducting magnetic energy storage (SMES) systems to quickly supply and absorb active and reactive power simultaneously. In [127], a novel frequency stabilization method is proposed, where EVs are used as storage systems for primary and secondary frequency control, thus suppressing fluctuations in the system frequency.…”

Countries around the world are transitioning from conventional power systems dominated by synchronous generators towards low-carbon resources, characterized by high levels of converter-interfaced generators (CIGs). With this transformation, hundreds or even thousands of fast power electronic devices will be added to the grid as CIG penetration increases, thus making the system dynamic response progressively faster and more complex. This future scenario poses significant challenges in power system stability and control. To sustain power system stability in future power systems and achieve a seamless transition, we need to depart from current control practices based on decentralized and stand-alone local control actions and begin to explore new methods. A promising technology to overcome control complexities and underlying stability issues in future low-inertia power systems are wide area control (WAC). Within this technology, the control is no longer based on a purely localized tasks but rather a set of coordinated actions across wide areas in which interplant communication plays a key role. This paper presents the state of the art of existing research efforts in the field of WAC strategies for maintaining stability in large-scale low-inertia power systems of the future. We present different WAC solutions that have been put forward hitherto, we put these control strategies into context, classify them, and finally relate them to each other. We also raise open questions and challenges that need to be addressed in order to ensure a secure transition towards power systems dominated by CIGs.

“…This is because, as data communication becomes essential in the utilization of PMU data, wide-area damping control system is in fact a networked control system [5], whose functionality is highly, though not exclusively, dependent on the performance of the supporting ICT system [6][7][8]. Among many ICT factors, the stringent delay requirement on input PMU data is considered as a major obstacle for the development of wide-area damping control system [9,10].…”
