Determination of the optimum site-matching wind turbine using risk-based capacity benefit factors

The amount of electricity produced by a wind turbine at a specific site depends on many factors, including the wind speed conditions at the site and the characteristics of the wind turbine generator itself, particularly the cut-in, rated and cut-out wind speed parameters. There are many different types of wind turbine commercially available. It is therefore desirable to select a wind turbine which is best suited for a particular site to obtain the maximum capacity benefit at the given criterion risk level. The paper shows how to determine the optimum site-matching wind turbine using risk-based capacity benefit factors. The effects of different wind turbine design parameters on the basic adequacy indices and the risk base capacity benefit factors are illustrated using a small test system.
