Operation Modes

The Grid Converter is used to make AC grids with a possibility to operate in parallel with other power sources.

The Grid Converter application has 3 different operation modes:

• Grid-tied/on-grid mode
• Island/off-grid mode
• Micro Grid mode

the converter acts as AC current source. In this mode, the converter transfers power between DC and AC. the converter cannot create grid by itself, it needs to be connected to existing grid.

Island mode generates constant voltage and frequency.

In island mode, power between DC and AC is not controlled. The energy flow depends on the vector sum of all the loads and all the generation in the AC mains.

Micro Grid mode controls the grid voltage and frequency.

It functions like an ordinary generator.

With the help of voltage droop and frequency droop, more than one Micro Grid and/or Generators can work together.
