In this paper, optimal control strategy for scheduling of household sources and loads during a demand response program is demonstrated. A nonlinear integer optimization mathematical model is formulated on a single household under time-of-use electricity tariff with dedicated PV-battery system. Baseline data is obtained from field measurements. The results show that by optimally scheduling residential electrical resources under time differentiated electricity tariff can accord consumers economic benefits while providing an advantage to the utility from the reduced and levelled power consumption from the grid thereby increasing system stability. The other advantage derived from this model is the mitigation of carbon emissions.
