| Abstract | ||
| This paper presents a probabilistic approach based on the convolution technique to assess the long–term performance of a Wind Energy Conversion System (WECS) for both stand–alone and grid–linked applications. A methodology is developed to use the proposed model to determine the maximum WECS installed capacity for a given number of turbines on a wind farm to satisfy the load with a certain Expected Energy Not Supplied (EENS). The technique is new in that it uses a simple procedure to estimate the joint probability distribution function of the total available wind power and that of the turbines operating modes due to hardware failure. Analytical expressions are developed to assess the reliability and cost benefits in electric power systems. The proposed method is applied to the IEEE Reliability Test System (IEEE– RTS ). | ||
