Wind system with storage in electrical accumulators

The aim of this paper is to obtain the energy stored in the electric accumulators (EA), for a wind system operating at a time-variable wind speed. Mechanical energy captured by the wind turbine (VT) is converted into electric energy by permanent magnet synchronous generator, PMSG. The synchronous generator provides energy into an electric accumulator, by using a rectifier, in two ways: uncontrolled rectifier and controlled rectifier and adjusted load. The simulations performed in this paper can highlight the differences between the two situations.
