Utilization of the IED devices in power system protection has provided the opportunity for power system engineers and System Operators (SO’s) to expand higher flexibility and resilience in designing protection schemes for future smart grids. However, the prospect of interactions between power system components and IED devices via ICT infrastructures networks have further complicated the process of validation and evaluation of the smart grid solutions. Thus, given the complexities corresponding to the operation of the smart grids, conventional power system analysis tools are not suitable to address reasonable detail and accurate time scales related to a multi-domain smart grid system including ICT-specific features. In this paper an adaptive-intelligent protection scheme is proposed to address the protection complexities arising from interconnection of DERs, utilizing smart grid concepts and its ICT infrastructure. Moreover, a holistic simulation approach based on co-simulation of power system and PHIL in real-time has been adopted to validate the proposed protection scheme. The outcomes of this paper are expected to highlight technical feasibilities in developing simulation testbed for research and studies in smart grid operation. Furthermore, capability of the modern IED devices for devising adaptive-intelligent protection system has been emphasised.
