“…In recent years, much research has been conducted on appropriate maintenance plans for different parts of the network, with an emphasis on reducing costs, improving system performance and reliability, and reducing interruptions. In most economic studies conducted in the field of his RCM for network maintenance, the objective function is modelled to minimize the cost of network maintenance and maximize reliability [1,6] modelled preventive and corrective maintenance planning in power distribution systems given considering various criteria, including economic criteria and reliability. This study reviewed various planning methods based on indicators, probability functions, constraints, and methods applied.…”

Planning maintenance of medium voltage overhead lines is one of the most important issues in the studies on power distribution network, which will prevent and reduce unwanted interruption. In this paper, long‐term maintenance of medium voltage networks was planned by multi‐objective function, including an extended mixed‐integer linear model to optimize costs, energy not supplied (ENS), and average interruption duration index (SAIDI). In addition, the uncertainty about the annual growth rate of the load, the increase in the cost of goods and services and the increase in the selling price of energy as well as various constraints are all included in the desired objective function, which is one of the main innovations of this paper compared to other published studies. To apply the uncertainties, information gap decision theory (IGDT) has been used, and to solve the objective functions, LP‐Metric method has been used. The proposed method was implemented on the standard 11‐bus RBTS network by MATLAB and GAMS. The results showed that three different long‐term maintenance plans proposed here lead to the optimization of the annual maintenance costs of network, reduction in ENS and interruption, and increase in the reliability of the network based on the uncertainty of each feeder.

“…The distribution network plays a crucial role in modern power systems, as it ensures that customers receive a reliable and high-quality power supply. With the integration of distributed energy, new requirements have emerged for the operation level of equipment, grid economy, and environmental sustainability (Trentini et al, 2021). This has also increased the demands on network planning, management, and maintenance (Gumpu et al, 2019).…”

In order to enhance self-monitoring and self-diagnosis capabilities in smart distribution networks, this paper proposes a method for assessing the health level of the network based on multivariate information. First, we construct an evaluation indicator system for the health of the smart distribution network by integrating the smart distribution network information system. Next, we utilize the improved back propagation (BP) neural network and multivariate indicator information to calculate the health indexes of both the grid layer and equipment. We then solve the health index of the equipment layer based on network topology and goal-oriented methodology. Furthermore, by utilizing the health information of both the equipment and grid layer, we apply fuzzy evaluation and Dempster-Shafer (D-S) evidence theory to obtain the health level of the distribution network. We provide a comprehensive evaluation of the overall health status of the smart distribution network. Finally, the proposed method is validated using data from a regional distribution network. The results demonstrate its effectiveness in improving the smart distribution networks’ overall health and stability by enabling more effective self-monitoring and self-diagnosis.

On the topic of power systems, the most critical assignment would be providing facilities to make electricity available at the lowest price with a fulfilled level of reliability for all consumers. Today, power transmission reliability has received more concentration due to the increasing essence of providing high‐quality energy to customers and operating competitive conditions in electricity markets. In this regard, this paper scrutinizes the reliability‐centred maintenance (RCM) issue in terms of considering two optimal maintenance strategies for transmission assets to decrease their forced outage rate (FOR). This techno‐economic budget‐based maintenance is a probabilistic approach to help asset managers and experts in the decision‐making process: to determine between maintenance strategies with associated costs and provide the most economical resource allocation for these elements, which leads to an improvement in the reliability of the whole network. Decreasing the average probability of Energy Not‐Supplied (ENS), the simulation determined the proper maintenance strategy for transmission components. After that, the repercussions of the fallen ENS will be analyzed in total maintenance cost (MC), operation cost (OC), and the system's total cost (TC). Also, the IEEE 24‐bus reliability test system is considered as a case study demonstrating the proposed technique's practicality.
