Seasonal Peak Electricity Demand Characteristics: Japan Case Study

Abstract: Because of the need to keep balancing between electricity supply and demand continuously, a demand analysis is necessary as it can provide essential information to manage operation of a power system. This study presents a seasonal peak demand characteristics investigation for commercial area in Japan by developing hourly demand regression models for each season. Meteorological parameters and existing holidays are considered as demand drivers. Many standard statistical tests are applied to the models. From resu… Show more

“…Beside demand models are not difficult to compose, obtained regression results provide specific information about direct relationship between observed electricity demand and considered variables which is relatively easy to explain. The same (regression) approach and procedure has used effectively by one author in previous works for Japan context as found in [5,6]. Beside contribute to understand more load behavior, presented information can useful to manage electric power systems under tropical condition effectively and may help policy makers to design suitable regulation for system operation.…”

“…From Table 1, hourly peak and off-peak demand models for residential and commercial areas are composed for comparison analysis. Applied variables in the hourly models especially for temperature variables (CDD and/or HDD) are based on the temperature condition in each season [8]. As extended from paper [8], some new analyses are presented in this study including introducing a new variable (wind speed) in the developed models with focus on the seasonal peak and off-peak characteristics comparison between observed electricity demand areas.…”

“…Besides, a representative hour for off-peak demand in both areas is also analyzed. Regression based hourly demand models [8] are used in this characteristics comparison study. Presented results may useful to manage power systems more effective especially to meet seasonal peaks (and off-peaks) from different areas in the same place.…”

“…Next, investigation of typical load characteristics particularly during daytime maximum demand period is done. From the previous work, one author has analyzed the peak electricity demand in Japan [7], [8]. It is hoped, this current research can contribute in managing power system under tropical condition mainly during maximum demand periods more effective, and further may help in determining proper needed actions to keep service to electric consumers.…”
