Enabling MVDC PV Collection Grids with Modular Solid State Transformers

Solar energy is typically collected through AC grids because of strong reliability and availability of standard solutions. The introduction of Solid State Transformers may not only allow reducing footprint and losses, but also implement peak shaving capabilities and the injection to MVDC grids directly. This work proposes an innovative PV energy collecting strategy with modular isolated DC/DC converters.
