Cascaded-connected string converter is an effective way to directly interconnect distributed low-voltage dc sources into higher voltage ac grids. When this system switched islanding operation, important task obtain decentralized power sharing among cells according the corresponding source capacity, and at same time, maintaining a good regulation of supply quality local critical loads. In paper, hierarchical control approach proposed simultaneously realize abovementioned two tasks. First,...
Series connection of low-voltage power cells has been considered as an alternative microgrid configuration to supply rated voltage point common coupling (PCC) loads. However, in the previous studies, major focus was on regulation system. Similar conventional shunt-distributed generation (DG)-unit-based islanded microgrid, PCC harmonic problem can be serious without any active control. In order provide enhanced quality this system, a flexible compensation approach is developed via...
