Degradation modelling and maintenance optimisation of PV panels affected by dust accumulation
Résumé
The objective of this paper is to discuss the problem of maintenance modelling and optimisation for a deteriorating Photo- voltaic panel system. In this paper, we model the dust accumulation process as PV panels’ as the main degradation cause considering the wind conditions as covariates. The dust accumulation process is mod- eled by a non-homogeneous compound Poisson process (NHCPP). The covariates process is assumed to be a time-homogenous Markov chain with finite state space. A model similar to the proportional hazards model is used to show the influence of covariates on the degradation process. In the framework of the system under consideration, an appropriate maintenance policy which minimises the long run average maintenance cost and maximises the long run average profits is derived. Numerical implementations are presented to illustrate the performance of the proposed model.
