“…The ACF gives an index value which shows the similarity in terms of a real number which remains in between −1 and +1, where +1 indicates perfect correlation and −1 indicates perfect anti-correlation. Mathematically, for M samples data, the correlation between the data at various time-steps (lags) can be given by (4):…”

There are two techniques to ensure that renewable energy systems run continuously: on-grid and off-grid. In the first case the system can be managed in a network, in the second case it can be managed in a micro grid or island mode. Islanding means when a distributed generator (DG) keeps running even after there is no longer any external electricity. This situation can be dangerous for utility systems because it prevents equipment from connecting properly. Therefore, this paper proposes an active method for detecting island patterns at a given time. The use of DG installations such as photovoltaics can cause islanding detection issues. In addition, the number of DG sets in the power distribution system will affect the accuracy of island detection (ISD). On a test example DC power supply linked to a 415 V, 50 Hz network, the suggested solution was put into practice. In the MATLAB Simulink environment, the proposed method's efficacy was assessed. The proposed method is compared with existing active methods and shortens the detection time.

“…In order to spread the cost of signal generator over multiple applications or in case of signal interference with AMR signal transmitters, the meter reading signal generator can be used for both islanding protection and AMR, deploying different signaling channels [4,5]. Furthermore, the proposed scheme in [3] was improved in [6] by adding the feature of main supply disconnection detection to the signal generator. This detection is done by examining the dc component of the upstream transient current created during the signaling process.…”

Recently, a new islanding detection scheme based on power electronic signaling technology has been proposed in the literature. By broadcasting a signal on the distribution feeders from the substation to the down-stream DGs, the absence of the signal at the DG site will be a sign of islanding. The scheme is more reliable than regular local detection techniques while it costs much less than transfer trip schemes. As the checking of the signal continuity is done via signal detectors, performance analysis of implemented detection algorithms is one of the main concerns. Since, the scheme relies on distortion broadcasting, our purpose is to answer the first question arises i.e., `` Is it a reliable scheme for DGs located at industrial areas that are rich in harmonics and interharmonics? ". Results show that for spectral based detection algorithms, more selective thresholds must be set in case of excessive interharmonic pollutions.
