SENSITIVITY OF HOURLY ELECTRICITY POWER CONSUMPTION TO TEMPERATURE AND HUMIDITY IN JAPAN

Abstract

 Highly fluctuating electricity demand causes an increase in the cost of electricity supply and the consumption of fossil fuel. To find countermeasures for global warming and ways to adapt to the warming of the urban thermal environment, it is important to clarify the relationship between climatic conditions and the hourly electricity demand. We constructed regression models that estimate power consumption based on various factors such as people's activities and multiple climatic conditions in order to understand the sensitivity of hourly electricity power consumption to temperature and humidity. Through the simulation by the model built, it was found that the influence of humidity is large in the summer: The higher humidity lowers the balance point temperature and increases the rate of power consumption per 1 °C.
