Cost-benefit analysis of electric power system reliability

Investigations of the impact of powerformer on composite power system reliability

“…The overall outage costs or customer interruption costs can be used as an important parameter to examine the optimal alternative among the potential candidates [28]. Benefits coming in the form of its reduction could be utilized as a parameter for ranking and screening the different alternatives.…”

“…In this regard a major issue of quantification of the benefits associated with modifying a power system by addition or removal of Powerformer TM on to the system adequacy could be simplified by using the total cost approach where the total cost is taken as the sum of capital cost, cost of customer interruption and fuel costs. However this total cost approach is relatively simpler and the cost benefit approach is the better and popular among the utilities [28]. To look at the impact of the different cases on the individual load point indices, analysis of the impacts on the load point indices of bus-18, bus-13, and bus-15 are considered in this study.…”

“…Στις αγορές ενέργειας, η αξιοπιστία (reliability) έχει περιγραφεί ως «η ικανότητα ενός συστήματος ηλεκτρικής ενέργειας να παρέχει υπηρεσίες προς τους πελάτες του, διατηρώντας την ποιότητα και την τιμή της ηλεκτρικής ενέργειας σε ένα αποδεκτό, ικανοποιητικό επίπεδο» (Abdullah and Mariel, 2010;Tinnium et al, 1994).…”
