| Summary: | 碩士 === 國立成功大學 === 電機工程學系碩博士班 === 96 === This thesis presents the analyzed results of stability, steady state, and
dynamics of an equivalent aggregated wind farm (WF) connected to a
utility grid through a transmission line with and without a flywheel
energy-storage system (FESS). The d-q axis equivalent-circuit model is
employed to establish the models for wind, wind turbine, induction
generator, and the FESS to derive the complete dynamic equations of the
studied system under three-phase balanced loading conditions.
Steady-state performance of the studied system under different wind
speeds and various control parameters of the FESS are examined.
Dynamic simulations of the studied system subject to torque disturbance,
voltage drop of utility grid, and variable wind speeds are also
implemented. It can be concluded from the simulation results that the
proposed FESS can effectively improve the performance of the studied
WF under disturbance conditions and variable wind speeds.
