“…In South Korea, the price of unplanned (unexpected) interruption for residential customer load is estimated as (a j =14.81 KRW/ kW, b j =148.1 KRW/kWh) according to information from KEPCO in 2010 as listed in Table 5. Furthermore, detailed definition and analysis of these unit costs in Finland were presented in [7]. The average failure rate of the power electronics converters is 0.3 faults per year/100 units and that for the pole mounted transformers is 0.5 faults per year/100units, with fault repair time (t rep ), respectively [8,9].…”

-Low voltage direct current (LVDC) distribution system is a suitable techno-economic candidate which can create an innovative solution for distribution network development with respect to rural electrification. This research focuses on the use of LVDC distribution system to replace some of KEPCO's existing traditional medium voltage alternating current (MVAC) distribution network for rural electrification in South Korea. Considering the technical and economic risks and benefits involved in such project, a comparative techno-economic analysis on the LVDC and the MVAC distribution networks is conducted using economic assessment method such as the net present value (NPV) on a discounted cash flow (DCF) basis as well as the sensitivity analysis technique. Each would play a role in an economic performance indicator and a measure of uncertainty and risk involved in the project. In this work, a simulation model and a computational tool are concurrently developed and employed to aid the techno-economic analysis, evaluation, and estimation of the various systems efficiency and / or performance.

“…According to [1] customer weighting would have directed the network operations too much to those secondary substations that have biggest number of customers at the expense of those secondary substations that have a couple of large customers. On the other hand, interruptions can also be modelled with interruption costs in the regulation of distribution companies, as well as for other purposes, too [3].…”

In this paper methods to take power quality factors (e.g. number and duration of planned and unplanned interruptions, number of auto-reclosing operations) account into efficiency benchmarking as outage costs is presented. The effects of outage costs in efficiency benchmarking are evaluated by means of sensitivity analyses. Effects of power quality factors in different kind of regulation models in actual network planning task are estimated.
