Chopperless Fault Ride-Through Control for DC Microgrids [PDF]
The dc microgrid should remain connected to the ac utility grid to support the grid stability during faults. However, the bidirectional power flow between the utility grid and the dc microgrid will cause either high-voltage or low-voltage faults at the dc bus.

Photovoltaic inverters with fault ride-through Capability [PDF]
This paper presents a new control strategy that allow the photovoltaic system operate under grid faults without overpass the rated current and assuring sinusoidal currents. In the classic control strategies used in photovoltaic systems the power delivered to the grid remains constant when a fault occurs, hence the current can reach dangerous values ...

AC Fault Ride Through in MMC-Based HVDC Systems
VSC-HVDC systems are being increasingly employed in the power systems. The recently installed HVDC systems have a power capacity similar to traditional power plants. Hence, they are expected to have a similar behaviour as traditional synchronous generators during faults in AC grid, within their limits of course. Recent grid codes require HVDC converter
