The MicMaq Project: Minimum cost — Maximum quality for the Maintenance Optimization of the Belgian Power System
In this paper, we propose a simple multi-component stochastic system model based on Petri nets for the simulation and evaluation of complex maintenance policies of the Belgian power system. The main objective of this modeling approach is to develop a decision-aiding tool in order to improve the maintenance decisions in terms of their consequences on the total maintenance costs and on the global performance of the power system. The model takes into account the different constraints influencing the maintenance policy. A single component, presenting two failure modes and periodically inspected and maintained according to its degradation level, is investigated first, before studying a system corresponding to a simplified feeder. A Petri net-based Monte Carlo simulation of these two cases is performed in order to estimate the costs entailed by several possible maintenance policies.
