N2 - We proposed and demonstrated a load-managing photovoltaic (PV) system that significantly reduces the levelized cost of electricity over conventional PV systems. Instead of managing the PV power, the system manages the number of loads connected to the PV array throughout the day to maximize the utilization efficiency of available PV power without a conventional maximum power point tracker. The system can also regulate its output voltage without a DC/DC converter. This paper presents a simulation study for a stand-alone load-managing system with direct-coupled ohmic loads. The simulation program can model a load-managing system with a PV array of any size and any number of loads, and outputs the power delivered to the loads. The theoretical utilization efficiency was found to increase with the number of loads being managed and reaches above 99% for a direct-coupled system with just eight ohmic loads. The voltage variation seen by the loads can be reduced to less than ±5% by adjusting the switch points for the loads.
