축열간접이용 EHP의 도입타당성 분석

The electricity demand in korea is continuously rising due to economic growth, higher living standards, different weather patterns caused by climate change, and wider distribution of electric devices. In particular, the increase of heating power consumption contributes to maximum in winter. Electric Heat Pump(EHP) is one of the factors that increases power consumption. In this work, we investigated the effect of EHP on the peak load of electricity and peak load shift of electric heat pump using indirect thermal storage. As a result, heating power consumption for EHP is 38% of total heating power consumption and effect of peak shift is 4.5% using indirect thermal storage in 2011.
