“…As previously described, research and development efforts to provide tools that can support the decision-making on the maintenance planning of EDS have been found in the literature because of the increasing relevance of this subject in the context of distribution networks (Briš et al 2017;Carnero and Gómez 2017;Mazidi and Bobi 2017;Arya 2016;Piasson et al 2016;Wang et al 2016;Yumbe et al 2016). Factors that can contribute to the definition of maintenance type were already raised in Beaumont and Geary (1944), as atmospheric condition, electrical and mechanical resistance, accessibility and physical layout of the system.…”

“…The MP problem has high dimension due to the number of alternative plans, as well as due to several options of preventive, predictive and corrective actions in short, medium and long term (Briš et al 2017;Salman et al 2017;Piasson et al 2016;Yumbe et al 2016;Wang et al 2016). Considering that the MP decision must be made within a suitable time, for instance on a monthly base, this decision must be supported by computational tools.…”

Electric distribution systems have the objective of supplying electricity with quality and reliability to the final consumers. In order to meet both criteria, efficient maintenance programs have a vital importance mainly due to the actual increase in the requirements for distribution service quality and in technologies related to electrical networks. In this sense, the number of options and criteria for developing effective programs makes the related decision-making process a complex task. This paper presents a comprehensive review on maintenance planning in electrical distribution systems covering different criteria such as economic and reliability. More specifically, this work summarizes contributions up to now through a holistic framework that comprises the premises of predictive, preventive and corrective maintenance. The work is organized by relevant aspects of researches in the field, as criteria, probability functions, constraints and methods that have been applied, within a comprehensive classification.

“…[15][16][17][18][19][20] The majority of the studies reported in the literature focus on designing a maintenance problem to determine the optimal maintenance rates. 8,[21][22][23][24][25] When the inspection rate is periodically based on the classical rate diagrams, the maintenance models are likely to provide accurate results. However, if the inspection rate is nonperiodic, the results of classic state diagrams are not precise.…”

Nowadays, the maintenance scheduling of equipment has been highly improved using condition monitoring (CM) systems. This paper determines the optimal inspection rate of circuit breakers equipped with CM using a novel mathematical procedure. To achieve this goal, in the first step, it is necessary to quantify the effect of CM on the early detection of minor failures of the equipment. Therefore, a mathematical formulation is provided to categorize and model the failures of the equipment based on their severity. Moreover, a new concept termed predictive maintenance (PDM) rate will be introduced and formulated in this paper. The PDM rate is applied in the maintenance process as the smart inspection rate of the equipment. In the second step, this paper proposes a new combined preventive and predictive maintenance Markov model. By developing the formulation of the proposed Markov model, an optimization problem is formed. In this optimization problem, the annual maintenance cost serves as the objective function and the inspection rates represent the decision variables. The comprehensive statistical study on the failures of 400kv‐CB of KREC in Iran and the implementation of the proposed method indicates that the CM and optimal inspection of the CB not only enhances the lifetime of the CB by 19.48 years but also lower the annual maintenance cost by 19%.

“…Analysis of operation of the distribution network can be carried out from different perspectives; one of them is supply reliability which is the key notion in the estimation of the supply continuity and service quality [1][2][3][4][5][6][7][8]. Evaluation of the reliability of LV networks is one of the important points considered in the analysis of the distribution power system.…”

Improving reliability of a power network is an issue of great importance for power distribution companies. The aim stated by the President of Energy Regulatory Office to improve the reliability of the distribution network includes steps towards improving the monitoring and control of the network managed by distribution companies. Ensuring continuity of energy supply is one of distribution companies’ duties and one of the criteria used to assess the effectiveness of network operation. Distribution companies all over the world employ indices SAIDI, SAIFI and MAIFI to determine mean values concerning the number of time of interruptions per consumer in a year. The paper deals with methods of correct and precise determination of the values of the reliability indices SAIDI, SAIFI and MAIFI by means of the application Advanced Metering Infrastructure in the distribution network.
