Abstract
-Smooth and fluctuation free power dispatch is strongly
encouraged by grid operators and therefore energy storage is
becoming an indispensable part in modern large scale grid
connected photovoltaic (PV) systems. As a result, associated
power converter topologies and energy storage interfacing
technologies are currently receiving unprecedented attention.
The most common energy storage interfacing technique used in
grid connected PV systems is the use of an additional power
electronic converter between the energy storage system and the
grid connecting inverter. Taking the disadvantages of this
implementation into account this paper proposes a dual inverter
based battery direct integration scheme for grid connected PV
systems. In this approach, the generation of proper multilevel
voltage waveforms is a complicated process, particularly when
the battery is charging. A modified space vector modulation
method and switching strategy are proposed in this paper to
address this issue. Simulation results are presented to prove the
efficacy of the proposed topology and the modulation technique.
