“…3) Pattern Search method One of the fast and efficient methods for minimization of the objective function is the Pattern Search (PS) algorithm. Initial research on the applicability of the PS method to the problem of optimal location of FPIs was presented in [21]. In this paper, the method is further improved in terms of setting the initial guess, increasing the stability of convergence and applicability to the problem defined in the probabilistic form.…”

“…In the second method (PS2) the step of the mesh is never doubled but only divided by two if certain conditions are met [21]. In this manner, one avoids the situation where optimal FPI locations fall beyond the main feeder.…”

“…Commonly, one FL is placed in the substation at the supply point of the network, while several FPIs can be placed at suitable locations in the distribution network. Because of significant costs related to the installation of FPIs, their exact number and positions for a given network must be determined in order to achieve a satisfactory ratio between installation costs and increased reliability [13]- [21].…”

“…Based on the research conducted in [21]- [24], the main goal of this paper is to propose a probabilistic techno-economic analysis for determining optimal number and positions of FPIs which will yield the maximum reduction of interruption time and costs both for networks with and without FLs. In order to take all influential factors into consideration, a comprehensive assessment methodology is developed and a simulation approach based on the probabilistic principle is employed.…”

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.
