A. Local DC Power Network With the advent of solar energy-based PV and wind energy as sources of generation and battery banks for storage, it is possible today to realize Edison's vision of dc generation and distribution. If the physical distance between power sources (generation and storage) and loads is small (power loss less than about 4-5%), an interconnected local dc power network can satisfy these loads with maximum efficiency. Figure 5 illustrates the local dc power network. The first part of Figure 5 is the low-power load (48 V) fulfilment through the PV, wind, and battery bank-based dc network. These loads are typical household appliances with low power consumption like LED lights, ceiling fans, Grid ac/dc Input VI Sensor ac/dc Power Inverter MCU ac/dc DSP ac/dc Analog Front End RTC ac/dc RTC: Real Time Clock DSP: Digital Signal Processor MCU: Microcontroller Unit CAN: Controller Area Network Communication Power RTC dc/dc dc/dc Analog Front End ac/dc Output VI Sensor dc/dc Input VI Sensor dc/dc Power Stage dc/dc Output VI Sensor MCU dc/dc DSP Relay Control Power Stage dc Earth Fault Protection All Sensors Communications (Ethernet/CAN) Controllers Relay Charging Station FIG 4 Reduction of capital cost for EV fast chargers if the input power is dc in place of ac [19].
