| Abstract |
To compensate power fluctuation caused by renewable energy sources, the concept of load control has been proposed. This concept is an idea to control the power consumption of loads in the power grid in order to contribute to the grid operator. In this paper, control of a heat pump air-conditioner is focused. Based on heat pump's characteristic obtained from experiments, a simple heat pump model is proposed. A simulation to compensate power fluctuation in a microgrid by use of the heat pump is conducted and the effect of the heat pump control is analyzed. The results of the simulation show that the necessary capacity of energy storage system(ESS) can be reduced by controlling the power consumption of the heat pump. At the same time, temperature simulation of the room which is air-conditioned by the heat pump is conducted to analyze the effect of load control to the user of the heat pump. The results show that the temperature fluctuation caused by load control is small enough to ensure the thermal comfort of the room. The feature of this paper is that the effect of the load control using a heat pump air-conditioner is discussed with consideration to the user's convenience. |
