“…On the other hand, hybrid IDMs based on signal processing technique [26,30] and communication-based remote IDMs [33,34,58] are accurate, efficient, fast, and reliable in detecting islands but they have high computational burden and cost concerns. Remote IDMs dominates the IDMs with its high speed of detection in the order of 20 ms with very small or almost zero NDZ.…”

Distributed Generation (DG) has changed the power generation system to small-scale instead of large-scale generation. The demanding issue with the interconnection of DG is the detection of unintended islanding in a network. Several methods proposed in the literature show drawbacks such as high non-detection zones (NDZ) and higher tripping time. In this paper, the IEEE 13 bus distribution network with DGs like wind and solar power plants is integrated at two buses. Islanding is detected by utilizing data from a micro-synchrophasor located at the distribution grid and the DG. The micro-synchrophasor-based unintended islanding detection algorithm is based on parameters such as voltage, rate of change of voltage, frequency, rate of change of frequency, voltage phase angle difference and the rate of change of the voltage phase angle difference between the utility and the islanded grid. The proposed islanding detection algorithm discriminates between islanding and non-islanding conditions and is highly efficient under zero power mismatch conditions. The proposed method has null NDZ and satisfies the IEEE 1547 standard for DG tripping time. The effectiveness of the proposed IDM was verified when there are multiple DGs in the islanded grid. Also, the proposed method does not require additional hardware as it can be incorporated in digital relays with synchrophasor functionality.

“…To the best of authors' knowledge, the existing protection schemes do not consider the phase angle jump information for coordination studies. The major contributions of this research are: (1) to investigate the effects of installing new DG on the voltage sag and protection coordination of utility network under different contingencies, (2) to improve an existing digital over-current relay with directional element using phase angle jump information, (3) to validate the performance and effectiveness of proposed scheme on simulated and real setups for its possible application in fields, (4) to examine the performance and robustness of proposed protection coordination scheme against other three state of art techniques.…”

“…Abnormalities include abrupt changes into the network characteristics due to different contingencies i.e., increased loading, frequent interruptions, sustained faults, etc. [1,2]. The traditional utility networks, being radial and passive are highly exposed to external disturbances but maintain their safety and security using conventional protection devices, as shown in Figure 1.…”

Distribution networks are inherently radial and passive owing to the ease of operation and unidirectional power flow. Proper installation of Distributed Generators, on the one hand, makes the utility network active and mitigates certain power quality issues e.g., voltage dips, frequency deviations, losses, etc., but on the other hand, it disturbs the optimal coordination among existing protection devices e.g., over-current relays. In order to maintain the desired selectivity level, such that the primary and backup relays are synchronized against different contingencies, it necessitates design of intelligent and promising protection schemes to distinguish between the upstream and downstream power flows. This research proposes exploiting phase angle jump, an overlooked voltage sag parameter, to add directional element to digital over-current relays with inverse time characteristics. The decision on the direction of current is made on the basis of polarity of phase angle jump together with the impedance angle of the system. The proposed scheme at first is evaluated on a test system in a simulated environment under symmetrical and unsymmetrical faults and, secondly, as a proof of the concept, it is verified in real-time on a laboratory setup using a Power Hardware-in-loop (PHIL) system. Moreover, a comparative analysis is made with other state-of-the-art techniques to evaluate the performance and robustness of the proposed approach.

“…As for generation, the fuels including natural resources are the starting point for the generation cycle, whereas the transmission network links the power production to the distribution system and the distribution system is responsible for distributing power to the end-users. Apart from such basic components of the power system, the monitoring and controlling devices are equally important for maintaining the reliability, quality, and security of power being distributed and utilized [2] [3]. Further, the proper placement and coordination of protection devices is also a crucial aspect for avoiding unnecessary power outages and mitigating the contingencies at initial stages before they get worse by the time [4] [5].…”
