Application of ordinal optimization on reliability centered maintenance of distribution system

Abstract

The problem of distribution system maintenance has a combinatorial explosion of choices. It may not be worthwhile to solve this problem using the analytical method that require too much time and cost. Ordinal optimization is a prime candidate of stochastic optimization problem. Ordinal optimization is used to quickly narrow the search space and find a good enough solution with reasonable confidence. This paper proposes the reliability centered maintenance model of distribution systems, and the solution of this problem through the application of ordinal optimization. A numerical examples are performed to illustrate the efficiency of the proposed ordinal optimization and to find a maintenance strategy of distribution systems.Maintenance has to be performed to reduce outages and maintain system reliability in RCM. Maintenance decisions are determined by considering the effect of equipment failure to the system. We proposed the equipment modeling through modified Markov chain [10] that is suitable for the concept of RCM. This model describes the deterioration process, inspection, and maintenance. Figure 1 shows the equipment model. Figure 1. Basic modified Markov chain model.

Mode-based reliability centered maintenance in transmission system

“…Various methods had been proposed in the literature for determination of the maintenance plan of power system components . In the work of Wang and Yang, the optimum maintenance plan of a circuit breaker is defined through curve‐fitting technology and the optimization problem is solved with particle swarm optimization.…”

“…In the work of Wang and Yang, the optimum maintenance plan of a circuit breaker is defined through curve‐fitting technology and the optimization problem is solved with particle swarm optimization. The maintenance scheduling of distribution systems is modeled by Park and Yoon with stochastic simulation, and the ordinal optimization is used to solve the problem. This problem is solved for a power transformer in a failure mode point of view through failure mode and effects analysis and analytic hierarchy process in the works of Liao et al and Suwanasri et al, respectively.…”

“…The maintenance scheduling of transmission elements can be categorized into 2 main groups: generation maintenance scheduling 1,2 and transmission maintenance scheduling. [3][4][5][6][7] In the first group the problem is solved from the generation company's viewpoint and the problem is solved in the deregulated power system. In the second group the maintenance plan is determined from the transmission operator's viewpoint.…”

A dynamic programming approach for optimal allocation of maintenance resources on power distribution networks

“…A AMP (Asset Management Planner) model [8] was used to describe the impact of equipment deterioration in the system. Some heuristic techniques such as, genetic algorithms [9], [10], particle swarm optimization [11], [12] and ordinal optimization [13] have been proposed to solve this optimization problem.…”

Modelling generator maintenance scheduling costs in deregulated power markets

“…In power systems, generators must be maintained in order to supply electricity with high reliability. Power generating companies (GENCOs) apply different maintenance strategies, such as reliability centre maintenance [4,29], corrective maintenance [4], preventive maintenance [6,7], age-based maintenance [19] etc., to achieve their objectives in terms of quality and cost. Regardless of the type of maintenance carried out, the generator units must be taken out of service for a period of time ranging from several hours to several weeks [13,32].…”
