The paper tackles the problem of the optimal sizing of a wind power system at the planning stage, consisting in the best choice among many alternatives-as a function of reliability and maintenance, both encompassed in the availability function of the system. Moreover, statistical methods to deal with uncertainty of such parameters are also discussed and illustrated with reference to typical values of wind turbines. In particular, the case studies refer to the sizing of generation capability of a power system, that consists in the choice of the optimal number and size of the generators (assumed as having all the same size and availability) to be installed for a given total installed power. The results show that the solution that features the highest availability might not be also the best in terms of expected performances, evaluated e.g. as expected energy not supplied. Finally, some numerical applications are illustrated regarding a new statistic methodology for handling the unavoidable randomness of the above availability parameters, in order to perform a rational choice among different alternatives.

Abstract
The paper tackles the problem of the optimal sizing of a wind power system at the planning stage, consisting in the best choice among many alternatives-as a function of reliability and maintenance, both encompassed in the availability function of the system. Moreover, statistical methods to deal with uncertainty of such parameters are also discussed and illustrated with reference to typical values of wind turbines. In particular, the case studies refer to the sizing of generation capability of a power system, that consists in the choice of the optimal number and size of the generators (assumed as having all the same size and availability) to be installed for a given total installed power. The results show that the solution that features the highest availability might not be also the best in terms of expected performances, evaluated e.g. as expected energy not supplied. Finally, some numerical applications are illustrated regarding a new statistic methodology for handling the unavoidable randomness of the above availability parameters, in order to perform a rational choice among different alternatives.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
