“…The reliability and the resilience of a smart grid architecture is dependent on the effectiveness of its protection systems. Many authors have proposed several adaptive and intelligent protection systems that use IEDs [167][168][169][170][171][172][173]. The IEDs, such as digital protective relays (DPR), have the capability to sense voltage, current and frequency, issue control commands, and process and communicate data.…”

Integration of high volume (high penetration) of photovoltaic (PV) generation with power grids consequently leads to some technical challenges that are mainly due to the intermittent nature of solar energy, the volume of data involved in the smart grid architecture, and the impact power electronic-based smart inverters. These challenges include reverse power flow, voltage fluctuations, power quality issues, dynamic stability, big data challenges and others. This paper investigates the existing challenges with the current level of PV penetration and looks into the challenges with high PV penetration in future scenarios such as smart cities, transactive energy, proliferation of plug-in hybrid electric vehicles (PHEVs), possible eclipse events, big data issues and environmental impacts. Within the context of these future scenarios, this paper reviewed the existing solutions and provides insights to new and future solutions that could be explored to ultimately address these issues and improve the smart grid's security, reliability and resiliency.

“…It is insensitive to fault level changes, so it only needs a single set of settings for its relays for a wide range of network conditions and it does not require a prior knowledge of the rated or fault currents in the circuit that needs to be protected. Moreover, the proposed protection scheme allows for normally‐open‐loop feeders to be closed without the need of voltage transformers, as in the case of directional OC relays [6] or additional current transformers (CTs). The newly developed protection scheme has been tested in a closed‐loop MV feeder with variable short‐circuit power using PSCAD and the simulation results demonstrate its effectiveness in these conditions.…”
