“…In addition, factors such as equipment damage reduction and risk of tripping due to heavy loading are also considered. An approach to find the optimal locations of AR using the cross-entropy method and the Monte Carlo method is presented in [23], where the objectives considered are reliability enhancement, minimization of the costs, and the occurrence of voltage sags. Reference [24] puts forward a combined process of an analytical method and PSO algorithm to determine the number and location of AR and switches, such that the reliability of the system can be enhanced.…”

The electric distribution system (EDS) is prone to faults leading to power interruptions. The present energy market demands that electricity utilities invest more in different measures to improve the performance of the EDS. The approach proposed here details a composite dual-phased methodology to improve the reliability and efficiency of the power delivered by the EDS. In the first phase, the optimal allocation of auto-reclosers (AR) is undertaken by employing a newly formulated algorithm. The determination of the total number and location for AR placement is based on the economic analysis of two factors, i.e., AR investment-maintenance cost and total benefit earned in terms of reliability improvement due to AR placement. The analysis also takes into account the impact of power outages on different load types, the load growth rate, and the inflation rate. Further, to enhance the efficiency of the AR-incorporated EDS, the technique of Radial Distribution System Remodelling is employed in the second phase. This method searches for a radial configuration that delivers power at minimum line losses. These phases comprising complex combinatorial operations are aided by a fresh hybrid of the Sine Cosine Algorithm, Krill Herd Algorithm, and a genetic operator of Differential Evolution. The results obtained from its application on the IEEE 69-bus distribution test system prove the credibility of the suggested formulation.

“…In the literature there can be found some recent works in this line. For example, reclosers are allocated in radial nonreturn lines in [14], where cross-entropy methods [15] are used to reduce the occurrence of voltage sags. Also, [16] places load switches and reclosers in theoretical bus test systems to reduce nonsupply energy, by using mixed integer programming (MIP) techniques.…”

“…Providing the optimal location of reclosers to minimize the power loss cost is presented in [21], but the recloser malfunctions and maneuver point effects are not studied. In [22], an approach to optimize the location of reclosers using the cross-entropy method and reassessment of Monte Carlo sampled states is proposed. However, finding the best neighboring feeders and the effect of the maneuver points on the optimal solution are not studied.…”

Improving reliability is one of the most critical problems in power distribution networks. Optimal placement of automatic switches improves system reliability. Practical constraints such as maneuver points and the capacity of neighboring feeders are often overlooked. Reliability indices may also be improved by optimizing maneuver point locations considering the capacities of neighboring feeders. In this paper, a new perspective on the problem of recloser placement in the presence of switch disconnectors (sectionneurs) with the ability to disconnect under load is proposed. The limitations of transmission power capacity at maneuver points are also considered in the proposed method. In addition, by proposing a Markov model, the possibility of malfunction of reclosers is considered. The proposed method is applied to two case studies including Roy Billinton Test System (RBTS) and the real distribution network in Mazandaran, Iran. Real system data are collected during the years 2016–2021. The problem is solved for various scenarios. In the case of 12 fully reliable reclosers, taking into account the optimal maneuver points and without any capacity limitations, compared to the allocation of maneuver points at the endpoints of the feeders show a %4.37 increase in the reliability of the real system. Even by considering practical capacity limitations in the maneuver points, this improvement is %3.47. Also, the results show a %6.684 decrease in the system reliability by considering malfunction in the case of 12 reclosers. This underscores the importance of taking into account the reclosers malfunctions in optimal switch placement for better decision making in practice.
