Onshore wind farms maintenance optimization using a stochastic model

Onshore wind farms maintenance optimization using a stochastic model

A specific feature of wind power generation is the stochastic behavior of wind velocity what determines the energy produced, and also influences the turbine degradation process due to the stochastic load suffered by the wind turbine. Thus, wind turbines present a degradation process more complex than the equipment that work under stationary conditions.The selection of maintenance strategy, that...

On maintenance optimization for offshore wind farms

On maintenance optimization for offshore wind farms FRANÇOIS BESNARD Abstract The maintenance cost is known to be an important part of the levelized cost of energy generated by wind parks. Operational costs can be significantly reduced by optimizing decisions for maintenance strategies, maintenance support organization and maintenance planning. This is especially important for offshore wind pow...

An integral maintenance optimization using a Gravitational Search Algorithm (GSA). An application to onshore wind farm

In Spain, the actual wind power capacity nearly reaches 20000 MW, what corresponds to a 16 % of the total capacity available to supply the electricity demand [1]. The amount of wind energy produced in the Spanish electric market has increased due to the construction of wind farms and to the improvement in their availability [2]. This improvement, is obtained by the analysis and continuous impro...

Optimal Maintenance Management of Offshore Wind Farms

Nowadays offshore wind energy is the renewable energy source with the highest growth. Offshore wind farms are composed of large and complex wind turbines, requiring a high level of reliability, availability, maintainability and safety (RAMS). Firms are employing robust remote condition monitoring systems in order to improve RAMS, considering the difficulty to access the wind farm. The main obje...
