An efficient building air conditioning system control under real-time pricing

In Smart Grid, efficient energy management strategy will be the key issues in the energy consumer side and the most important factor to make the people smoothly and voluntarily participate in this newly emerging energy infrastructure. In Korea, Residential and commercial buildings are consuming about 40% of total energy usage and a half of building energy is used for heating, ventilating, and air conditioning (HVAC). Therefore, if we efficiently manage the energy usage of HVAC in the buildings, then the building consumers reduce their total energy consumption and get economical benefits from participating in smart grid. This paper propose the efficient energy management method for building HVAC system where the temperature setting of chiller in HVAC system is controlled to minimize the electricity cost under real time pricing tariffs.
