Abstract
In this paper, a wind energy conversion system interfaced
to the grid using a dual inverter is proposed. One of the two
inverters in the dual inverter is connected to the rectified output
of the wind generator while the other is directly connected to a
battery energy storage system (BESS). This approach eliminates
the need for an additional dc–dc converter and thus reduces power
losses, cost, and complexity. The main issue with this scheme is
uncorrelated dynamic changes in dc-link voltages that results in
unevenly distributed space vectors. A detailed analysis on the effects
of these variations is presented in this paper. Furthermore,
a modified modulation technique is proposed to produce undistorted
currents even in the presence of unevenly distributed and
dynamically changing space vectors. An analysis on the battery
charging/discharging process and maximum power point tracking
of the wind turbine generator is also presented. Simulation
and experimental results are presented to verify the efficacy of the
proposed modulation technique and battery charging/discharging
process.
