| Abstract |
In the current progressive rate, the electricity bill is calculated based on the usage of electrical energy and corresponding progressive ranges. The time-of-use (TOU) electricity rate, in which the electricity bill is calculated based on different rates depending on the electrical energy used by season and time of day, is comparatively analyzed in this paper. For an experimental analysis, we used practical metering data of 593 households through an advanced metering infrastructure based on the progressive rate. Using the metering data, if we calculate the electricity bills based on the TOU rate, then 22.6% of the total number of billing showed reduced bills and 77.4% showed increased bills. Note that the households of the former case paid relatively high electricity bills based on the progressive rate. We then observe the pros and cons of the TOU rate comparing to the progressive rate through the experimental analysis in terms of the electricity bill. We could observe that the TOU rate is more advantageous than the progressive rate case when the annual electricity bill is higher than 704,000Won and the progressive rate is more advantageous than the TOU rate case when the annual electricity rate is less than 599,000Won. |
