Abstract
Abstract the DC house house project is a pure DC electricity system to enable optimal use of renewable and alternative energy, DC House promotes a more sustainable solution by not using fossil based fuels. DC sources are mainly from renewable generation such as PV and wind turbines, the output from PV and Wind turbine produced is not stable, so there is a need for a regulatory system, arrangements can be made on the generation side and on the load side. Because the output of the generator is not constant, a setting on the load side is needed to adjust the generation capacity. If one of the offsets is to be released, a load shedding must be carried out to meet the load requirements. Release of load is carried out when the supply is reduced because one of the generators is off then the low priority load will be released automatically. In this study simulated DC loads using PID control on the buck converter and load release using switching four loads with priority scale. The DC current sensor is used to determine the amount of current when determining the load released due to limited supply from the source
