Abstract
This paper describes a diode-clamped three-level
inverter-based battery/supercapacitor direct integration scheme
for renewable energy systems. The study is carried out for three
different cases. In the first case, one of the two dc-link capacitors of
the inverter is replaced by a battery bank and the other by a supercapacitor
bank. In the second case, dc-link capacitors are replaced
by two battery banks. In the third case, ordinary dc-link capacitors
are replaced by two supercapacitor banks. The first system is
supposed to mitigate both long-term and short-term power fluctuations
while the last two systems are intended for smoothening
long-term and short-term power fluctuations, respectively. These
topologies eliminate the need for interfacing dc–dc converters and
thus considerably improve the overall system efficiency. Themajor
issue in aforementioned systems is the unavoidable imbalance in
dc-link voltages. An analysis on the effects of unbalance and a space
vector modulation method, which can produce undistorted current
even in the presence of such unbalances, are presented in this paper.
Furthermore, small vector selection-based power sharing and
state of charge balancing techniques are proposed. Experimental
results, obtained froma laboratory prototype, are presented to verify
the efficacy of the proposed modulation and control techniques.
