“…The cost effectiveness of the method is tested and verified afterwards. One of the first ideas for indirect approach is the fuzzy method [17], [18]. Instead of computing precise positions appropriate for installation of FPIs, the method provides the results in a form of a chart which shows the installation potential for each bus along the main feeder, which represents distance from the network substation to the farthest network bus [19].…”

Fault passage indicators (FPIs) and fault locators (FLs) are employed in modern distribution networks in order to enhance the process of fault localization, thus resulting in reduction of interruption time and improving the reliability of power supply. In this paper, a novel probabilistic techno-economic optimization method is proposed for determining the number and positions of FPIs that lead to maximum reduction of interruptiontime and investment costs in medium voltage (MV) distribution networks with and without FLs. The proposed method is basedon a probabilistic non-sequential Monte Carlo simulation model of the real network, which is a proper compromise between complicated sequential simulation models and too simplified analytical models. The main goal of the method is to obtain maximum improvement of the network reliability indices while using the minimum number of FPIs. The method is tested on a combinedurban/rural MV distribution network in Bosnia and Herzegovina and results are thoroughly discussed.

Summary In distribution systems, fault indicators (FIs) are used for fast faulted line‐section location. Locations and the numbers of FIs affect the reliability indices of distribution companies and customers. This study presents a new linear method to find the optimum numbers and locations of FIs in distribution systems. Fault indicator placement of FIs is defined as an optimization problem whose aim is to improve the reliability indices with regard to the costs imposed on the system. The structure of the proposed formulation is mixed‐integer linear programming. The proposed approach finds the optimal locations for FIs in such a way that customers' interruption cost and investment costs for the installation of FIs are minimized. The proposed formulation can be solved by using commercial solvers in a computational effective manner and rapidly converges to the global optimum. To evaluate the effectiveness of the proposed mixed‐integer linear programming optimization formulation, several studies are presented and tested on bus number 4 of the reliability test system.
