Thermal comfort analysis during power fluctuation compensation by use of air-conditioning system

The power consumption control of hat pump air-conditioning system (HPACS) is expected to be an effective method to reduce energy capacity of energy storage systems (ESSs) that is necessary to compensate power fluctuation caused by renewable energy sources. In this research, experiments to control HPACS's power consumption directly has been conducted using real machine. The input signal of the HPACS has been calculated by microgrid control simulation. The heat output of the HPACS has been measured and thermal comfort of the room that is air-conditioned by the HPACS has been analyzed using room temperature calculation model. The results of the experiments and analysis show that by implementing appropriate temperature control loop, the HPACS can compensate power fluctuation in frequency range between 0.005Hz and 0.01Hz without affecting thermal comfort of the users.
