NDLI: Islanding protection of multiple distributed resources under adverse islanding conditions

Abstract	This study proposes a methodology based on multivariate analysis and data mining techniques that credibly captures the signature of the DG-islanding phenomenon under adverse operating conditions and network faults. This methodology produces decision trees which determine the tripping logic, protection handles and thresholds for each DG-islanding relay within the distribution network under study. Case study results indicated that the intelligent islanding relay (IIR) produced by the proposed methodology is consistently high-level performance in terms of dependability and security, and features reduced non-detection zones compared with the currently used islanding devices. It is also demonstrated how to determine adaptive settings to accommodate entire ranges of system operating conditions applicable to different ranges of power mismatches (overbalance, underbalanced and near balanced) at the point of common coupling bus. Experimental validation for prove-of-concept of the proposed IIR using hardware-in-the-loop has been conducted which was consistent with the off-line test results.
