“…This condition imposes no sustained interruption on load point i. The deduced formulas and procedures for determining the impacts of the introduced SAS on the substation reliability can be summarized in the following steps: (1) Determine the contribution to the sustained interruption frequency and annual outage time of load point i by component C j on the basis of the concept of expectation method and the restoration probabilities identified in section II as [11][12][13]:…”

“…This approach relies on the event tree technique and follows the basic concepts that have already been developed by the authors for reliability assessment of the automated distribution systems, e.g. [4] and [5]. Susceptibility of customer operations against voltage sag events depends on the voltage tolerance capabilities of its equipments against these events.…”

The business activities of the majority of industrial and commercial customers are dependent on some critical equipments that are susceptible to voltage sag events. This paper aims to propose a novel approach to estimate the financial impacts of voltage sag events on customer operations. The proposed technique is based on the event tree method. Using this approach, it is possible to consider the impacts of operational failure of various sensitive equipments, involved in the customer operations, on the financial losses expected from voltage sag events. A quantitative case study is conducted in the paper to illustrate the applicability of the proposed approach.Index Terms-Event tree, interruption cost, power quality, voltage sags.

Summary To avoid a long radial transmission line and the difficulties of right of way, the bulk consumer prefers to get the electric supply directly from its nearest point of the grid through loop‐in and loop‐out (LILO) connection. This affects the reliability of a transmission corridor. A small percentage of decrease in the reliability of a transmission corridor can create a significant impact on global reliability of a grid. This paper develops reliability models for different configurations of LILO connection based on the basic network reduction approach and probability laws. The developed models can easily incorporate any change in the physical network in reliability calculation. The models are applied to a real power system with a view to investigate the impact of LILO connection on the reliability of a transmission corridor. The investigation includes different configurations of LILO connection, different number of LILO consumers, and different types of LILO lines and also the effect on the reliability of a load bus in the corridor. The study shows that the reliability of a transmission corridor with LILO connection deteriorates than its base counterpart and it becomes worse as the number of circuits broken to feed consumer's substation is increased. The grid reliability degrades most if underground cable is used in the LILO connection. The results should prove useful for the electric utility.
