“…Previous studies have been undertaken to relate the evaluation of economic costs of these phenomena by proposing weighting factors [8,19,26,27]. According to the logic presented by McGranaghan and Roettger [26], the cost of the momentary interruptions are accepted as the base with a base factor of 1.0.…”

“…Another failure risk assessment study for modeling the voltage susceptibility for the industrial processes is provided by Chan et al [7]. A study by Lin et al [8] adopted the Tobit model to estimate economic losses due to voltage sags. On the other hand, monitoring stands as the best way of recording the characteristics of events and then calculating the corresponding Customer Voltage Sag Costs (CVSCs).…”

Abstract:The electric power sector has changed dramatically since the 1980s. Electricity customers are now demanding uninterrupted and high quality service from both utilities and authorities. By becoming more and more dependent on the voltage sensitive electronic equipment, the industry sector is the one which is affected the most by voltage disturbances. Voltage sags are one of the most crucial problems for these customers. The utilities, on the other hand, conduct cost-benefit analyses before going through new investment projects. At this point, understanding the costs of voltage sags become imperative for planning purposes. The characteristics of electric power consumption and hence the susceptibility against voltage sags differ considerably among different industry subsectors. Therefore, a model that will address the estimation of worth of electric power reliability for a large number of customer groups is necessary. This paper introduces a macroeconomic model to calculate Customer Voltage Sag Costs (CVSCs) for the industry sector customers. The proposed model makes use of analytical data such as value added, annual energy consumption, working hours, and average outage durations and provides a straightforward, credible, and easy to follow methodology for the estimation of CVSCs.
