Estimation of potential demand reduction by commercial air conditioner control considering outdoor air temperature

Abstract

Demand response is expected to help maintain the supply and demand balance of the power system. In Japan, various demonstration projects have been carried out to evaluate the effect of demand reduction. Commercial air conditioners are a promising responsive load for demand response because they account for a large proportion of power consumption in the power system. In this study, we estimate the potential for system-wide demand reduction through controlling commercial air conditioners. Power consumption of air conditioner changes by the outdoor air temperature. The airconditioning power consumption model is established based on efficiency characteristics of air conditioner depending on outdoor temperature and load factor. A thermal load simulation is performed assuming demand response implementation in the model buildings and the potential demand reduction is estimated considering user comfort. Our results show that demand reduction through air conditioner control is a viable strategy.

Economic Evaluation of Power System Flexibility by Commercial Air Conditioner Control with Large Penetration of Photovoltaic Generation

“…We estimated the DR potential by comparing the output results of the air conditioning load factors with and without DR [18]. In this paper, we simulated a case in which we controlled the air conditioners in buildings modeled as offices, wholesale shops, and retail shops.…”

We used the building energy simulation tool (BEST), developed by IBEC, to evaluate the DR potential [19].…”
