In this paper, a sequential power flow calculation method for high- and low-voltage distribution systems is proposed. The proposed method is employed to assess the energy losses for a single-phase, 3-wire, 2´110V branch circuits of a typical dwelling unit. The daily, weekly, monthly and annual energy losses of a dwelling unit are obtained by a succession of precise power-flow analyses considering the daily and seasonal use of lighting and typical electrical appliances in a dwelling unit. Based on numbers of dwelling units or households and detailed analysis results of their power consumption, the energy losses, financial loss and carbon emissions of dwelling units in Taiwan are presented. The outcomes are of value to residential and commercial buildings for energy conservation and the implementation of sustainable development policies in Taiwan.
