Analysis of Residential Electricity Usage Characteristics and the Effects of Shifting Home Appliance Usage Time under a Time-of-Use Rate Plan

“…For a standard washing capacity of the electric washing machine D1 (24 kg), the monthly energy consumption is W 1 ≈ 10 kWh. For the case of D1, if each household shifts the same energy consumption of W 1 = 10.022 kWh/month for 12 months, from (15), which takes into account all the seasons, the annual savings for each household is Bs = Bs = 805.6 × 10.022 ≈ 8074 KRW. Figure 17 shows the annual savings of B s per household for the normal washing machine N1 and drum washing machine D1.…”

“…From the TOU rate plan and ( 22), we can then save KRW 3300 per month in spring/fall from 40.299 × (188.8 − 107.0) = 3296. The bill saved from (15), considering all the seasonal factors, is about Bs ≈ 32500 KRW per year. Figure 17 also shows the annual savings per household for Dryer 1.…”

“…Note that most of the studies on the DR effect of dynamic rate plans, such as TOU, are based on load management methods for home appliances in a specific household. Yu et al [14] performed an optimization scheme in usage of home appliances, and Zhang et al [15] conducted a study on the integrated DR potential and characteristics through scheduling of home appliances for multiple households connected to a specific distribution line. Chung et al [16] comparatively analyzed the current progressive rate plan and a dynamic rate plan of TOU.…”
