Unified Control Strategy for Microgrid Solid-State Transformers
Solid-state transformers (SST) are particularly useful components in distributed
generation systems (DG). This research approaches the control of the SST in a
more comprehensive and an organized way. It proposes a compact, versatile and
an efficient unified control strategy. This proposal gives rise to three more
proposals.
i) A method to mitigate the current harmonic distortion which is uniquely
software-based and ii) An efficient low-voltage ride-through (LVRT) scheme. Both
of those functions come at no extra cost using the proposed unified control
scheme. These proposals further demonstrate the proposed strategy’s ability to
accommodate further features and modifications.
A further contribution to this research addresses the unbalanced load conditions.
It proposes a simple, cost-free modification to a resonant filter - making it suitable
for the proposed control strategy thus maintaining its simplicity without
compromising its practicality.
All the proposals of this research have been validated through simulation in
Simulink
