The use of series capacitors is to reduce the voltage drop in the lines with low power factor
and improve the voltage at the receiving end particularly with low power factor loads. For …

Synchronization with the grid voltage is critical in the control of grid-connected power
converters. Under unbalanced grid condition, the conventional synchronous reference frame …

One of the critical components for the efficient operation of single-phase grid-connected
converters is the synchronization unit. This paper presents a fast and adaptive phase-locked …

The actual grid code requirements for the grid connection of distributed generation systems,
