Zero energy house are emerging as a solution for global climate change and energy depletion. To build a zero energy house, it is necessary not only to use passive technologies that minimize energy loss, but also use energy efficiency technologies and renewable energy technologies. Photovoltaic (PV), which is a representative renewable energy source for zero energy house, needs an energy storage system (ESS) to supply power at any time because the PV power system (PVPS) only supplies power during times of solar radiation. In addition, the ESS is used to reduce electricity prices by shifting the peak loads in Time-of-Use (TOU) rates. In Korea, a residential ESS is not available because of the high price of an ESS, a low electricity price, a progressive rate scheme (or increasing block rates), and a low penetration rate of residential with PVPS. This paper presents the conditions in which a residential ESS with a PVPS are applied using HOMER (Hybrid Optimization of Multiple Energy Resources) in Korea.
