Abstract
This paper presents a capacitor-clamped three-level
inverter-based supercapacitor direct integration scheme for wind
energy conversion systems. The idea is to increase the capacitance
of clamping capacitors with the use of supercapacitors and allow
their voltage to vary within a defined range. Even though this
unique approach eliminates the need of interfacing dc–dc converters
for supercapacitors, the variable voltage operation brings
about several challenges. The uneven distribution of space vectors
is the major modulation challenge. A space vector modulation
method is proposed in this paper to address this issue and to generate
undistorted currents even in the presence of dynamic changes
in supercapacitor voltages. A supercapacitor voltage equalization
algorithm is also presented. Moreover, control strategies of the
proposed system are discussed in detail. Simulation and experimental
results are presented to verify the efficacy of the proposed
system in suppressing short-term wind power fluctuations.
