Abstract
Nanogrids would become a relevant concept during the COVID-19 pandemic since everyone has to do all their activities at home. This paper proposes a new topology of hybrid nanogrids called “Dual Power Nanogrids” to improve the reliability and resiliency supply in residential sector. In this system, the voltage is divided into two parts, first is the AC voltage which is supplied through an inverter 230 VAC to feed the motor/inductive loads, and the second one is DC voltage through a DC–DC converter with an output voltage of 230 VDC to supply the SMPS (switch load power supply). The PLC-IoT is embedded to the system to anticipate fault conditions. At the DC side, the voltage remains stable at the 230 VDC during dynamic loads condition. During transition from DC to AC, the system could recover the voltage stability in 2 s. Furthermore, during the serial failure at the DC–DC converter and utility grid supply, the voltage is stable, and the load still run properly. The role of battery is strategic as a last source against the various disturbance. The Dual Power nanogrid could guarantee the power reliability and resiliency when the blackout occurred in the utility grid.
