It is clear that the widespread introduction of DG and ANM schemes and the potential for islanded operation of networks in the future will present significant challenges to existing network protection. This paper has illustrated how an adaptive protection scheme can act to address many of these problems and has demonstrated its implementation using a realistic model of an actual distribution network with commercially available hardware and communication schemes. The novelty of the adaptive overcurrent protection system proposed in this paper is in its algorithm, which differs from other adaptive protection solutions presented in the literature in terms of its possession of higher flexibility and comprehensive coverage of all events that may influence the behavior of the protection system. The algorithm has been explained in detail, focusing on the protection settings calculation technique and the protection system-response evaluation. The proposed adaptive protection solution is more flexible with respect to other solutions presented in the literature, which are largely based on precalculated protection settings and settings groups. The limitations of using setting groups with precalculated settings is overcome by calculating the optimal protection settings in real time and applying them, after verification of their effectiveness using model-based performance evaluation, to the OCRs when the network status changes.
