“…The apartment complexes then lower the incoming medium voltage into a low voltage of 220 V by using their electrical power facilities, which are maintained by the apartment management offices. Here, maintaining electricity energy meters and reading the meters are operated by the management office as shown in Figure 1 [2][3][4]. Here, the advanced metering infrastructure (AMI) can efficiently provide metering data to the apartment management offices as well as electricity suppliers.…”

Analysis of the Electricity Supply Contracts for Medium-Voltage Apartments in the Republic of Korea

For apartment complexes receiving medium-voltage electrical energies, the apartments can choose an electricity charging method between the single and general contracts in the Republic of Korea. In the single contract, a residential high-voltage rate is applied to the total electrical energy consumptions of households and common areas. On the other hand, in the general contract, different rate plans are applied to the electrical energy consumptions of households and their common areas, where a generic high-voltage rate plan is applied to the common consumption. Hence, depending on the amounts and composition of the consumptions, both contracts have their own strengths and weaknesses in terms of the total electricity charge. The management office of an apartment complex can select its preferred contract considering the amount and composition of the power consumptions on an annual basis. In this paper, we first formulate a model for the contracts and analyze their properties based on Monte-Carlo simulations. We then observe the contract properties through actual metering data from 30 apartment complexes in Korea. From the analysis of this paper, we can select appropriate contract for a given apartment complex and have guidelines for saving electricity charges. The greater the consumption of the electrical energy and the common area portion, the more advantageous the general contract is in terms of reducing electricity charges.
