Abstract:Most renewable energy sources are operated in direct current (DC) and require dedicated inverter to be integrated in the power system. This results in loss of rotational inertia as well as degradation of the power quality (PQ) indices. A promising alternative is represented by low-voltage DC grids, whose standardization though is still incomplete. Reference systems are being developed for DC metering and DCPQ, but their validation requires inter-laboratory comparison. To this end, we propose the design and pre… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
