実測データに基づく住宅の消費電力のならし効果に関する分析

摘要

本稿では、柏の葉キャンパス周辺にある住宅における49戸の世帯の消費電力の1分間隔で計測した実測データを用いて、住宅の消費電力の平準化について検討を行った。その結果、統合する世帯の数が多くなるにつれて、平均消費電力の1分における最大変化量が小さくなった。また、変化量の平均と標準偏差も世帯数が増加するにつれて、小さくなることも確認できた。%Before clarifying the roles of HEMS and CEMS, it is necessary to take notice that the consumption pattern under each system differs from one another. Because residential electricity consumption patterns vary depending on family structure, home appliance and life style, electricity consumption with high fluctuation is smoothened when aggregated with that of other households. This paper presents the analysis of the smoothing effect that can be seen in the average of electricity consumption of a community of multiple residents using measured consumption data of 49 households. The results show as the number of residents in the community increases, the highest of electricity consumption change per minute decreases. The average and the standard deviation of the change of electricity consumption per minute decrease as well. However, decrease in rate of change of those three can be observed as the number of household grows.
