Abstract

The trend of converting direct current (DC) system into alternating current (AC) using inverter becomes common since the system efficiency appropriately improves. Additionally, the mitigation on direct-DC power system requires transformer and inverters inside the appliances due to lower and convert the 230VAC into useable DC voltage. This paper proposes the direct-DC power system generation based on single-phase rooftop photovoltaic (PV) in the residential low voltage (LV) feeder. The proposed simulation designates the power system components included in the modeling of the AC and direct-DC houses, which the included power system components downstream of the PV array. The efficiency of direct-DC power supply, grid interactive inverter and charge controller are simulated. The results show that the peak curve efficiency of direct-DC power supply has DC power input narrow to 400VDC. It is then become 2% higher than 220VAC power input. While the inverter with multiple MPPT efficiency curve has the peak of 96-97% after 30% loads, while when it is partly loads, with the power capacity below 1000W, has peak at range of 86-95%. Then the efficiency curve of charge controller with MPPT for partly load scheme below 30W output power the peak is about 90-94%.
