ELECTRICAL PROTECTION OF MICROGRIDS

EMERG - Energy. Environment. Efficiency. Resources. Globalization
The present work originates from the necessity of evaluating the electrical supply scheme of a bus charging station. Based on this framework, a microgrid model interconnected with the public network was developed, within which the calculations and dimensioning of short-circuit currents and transformer operating voltages were carried out.
