In hybrid systems which include wind turbines, calculation of wind turbine power is based on average wind speed, because considering instantaneous wind speed makes the design of the hybrid system complex and practically impossible. In this paper a new method is presented to determine the optimum generation capacity and storage needed for a hybrid (wind/PV/battery) system, based on instantaneous wind speed variations. In this method, the power curve of the wind turbine is modified on the basis of wind speed variations. The modified power curve is obtained by considering the energy pattern factor of actual wind as an indicator of the wind dynamics and using a new factor called wind turbine controllability for performance evaluation of the wind turbine controllers in capturing extra energy. The hybrid system calculations will be based on this modified power curve.Results indicate that by using this method and designing hybrid systems based on wind dynamics, the power of different hybrid system components can be calculated more accurately and, while maintaining the system reliability, there will be a significant reduction in the investment cost.
