“…Recently, some computational intelligent methods in combination with modern signal processing techniques have been introduced to get rapid detection of islanding condition, such as artificial neural network, [11][12][13][14][15][16][27][28][29][30][31] fuzzy logic, [15][16][17][18]28 and wavelet. [15][16][17][24][25][26][27][28] In spite of the outstanding features and the capability of these intelligent methods to determine the most proper combination of features, as well as thresholds, that can reduce the NDZ, such intelligent methods need additional software and hardware support and are difficult to implement in practice.…”

The challenges for a reliable operation of electrical power system have increased due to the presence of multi-distributed generation units (DGs) in the distribution systems in order to meet the increase of the load demand. Detection of unintentional islanding situation is very important as nondetection of islanding situation could result in a cascaded failure of the system. If the islanding situation remains undetected, the instability in the islanded part can lead to a complete failure of the electrical power system. This paper introduces a new passive scheme for islanding detection, which is suitable for multi-distributed generation units based on rotating machines. The proposed method is based on the measurements of the system voltage and frequency to compute two indices called the islanding index and harmonics index. The islanding index is the main index used to discriminate and identify the islanding situation. However, the harmonics index in conjunction with a strategy called speed reduction strategy assists the islanding index to discriminate between islanding situation in case of a close power match and system disturbances. The simulation studies were conducted in MATLAB/SIMULINK environment, and various cases have been considered, such as normal operation, islanding operation, sudden load change, DG tripping, separation of some DG units, faults, etc. The novelty of the proposed strategy is that it provides fast detection and has zero nondetection zone compared with the existing detection methods. Moreover, the proposed strategy has no effect on the power quality, and the maximum detection time is almost 350 ms at a close power match. The results indicate that the proposed scheme is successful in discrimination of the islanding conditions from other grid disturbances, revealing its great potential to be able to detect islanding events. Finally, the proposed method is applied only for rotating machine based DGs, such as wind turbines. Wind farms'

“…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],…”

“…In particular, multi-agent frameworks are proposed in [202] and [258], where intelligent agents coordinate protection devices to isolate the faulted part from the rest of the system before a critical clearing time, thus increasing the transient stability margin of the system. Controlled islanding approaches were proposed in [139], [210], [218], and [234]. In these schemes, the network is split into stable islands to avoid disturbances propagation.…”

Review of Wide-Area Controllers for Supporting Power System Stability

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.

Energy Storage Systems installed at primary substations can be used by different participants of the power system for handling the emerging uncertainties caused by supply-side variations, demand-side flexibility and grid topology changes. This work presents a practical design for the monitoring system of the controller of the grid interactive energy storage system. This monitoring scheme takes advantage of synchrophasor measurements gathered by phasor measurement units of wide area measurement systems. The analysis of synchrophasor measurements provides real-time situational awareness over the status of the grid. Therefore, the integration of synchrophasor measurements into the control loop of GI-ESS will enable them to participate in power services of the flexibility market. Furthermore, the implementation of a basic power oscillation damping function as an example of power services using the proposed monitoring system is illustrated in this paper.Keywords: Phasor measurement unit Á Grid interactive battery energy storage system Á Wide area control system © The Author(s) 2020 B.
