Fault-ride-through strategies for grid-tied and grid-forming smart

In the moments subsequent to the islanding, the grid forming ST supplies part of the load in the grid tied ST. In fact, the grid-forming ST assumes the provision of active power (previously provided by the main power system) required by the grid-tied ST to attend the power unbalance in its hybrid AC/DC network.
