Optimization of power generation and maintenance for a wind turbine under stochastic climatic conditions

This paper presents an optimal integrated energy production and maintenance policy for a wind turbine under stochastic climate conditions. A mathematical cost model is developed in order to determine, for a given random demand over a finite horizon and a required service level, the amount of energy to be produced and periodic preventive maintenance to be performed on the wind turbine. The model takes into account the influence of stochastic climatic conditions on the wind turbine failure rate. Costs related to operations and maintenance are considered along with energy storage capacity. Obtained numerical results illustrate the use of the proposed model.
