In this test case, STS is open () and the inverter caters to the power demand from the three-phase load. The three-phase loads are configured to operate in constant power mode with the current limit of 8 A. Measured data from the spectrum analyser are fetched and plotted for controller performance analysis.
Due to the pulsating voltage at the three-level inverter output nodes, some kind of filter has to be in-serted between the inverter and the grid to attenuate the switching harmonics. The filter is usually composed of inductors and capacitors, which allow the inverter to exchange active and reactive power with the grid by means of inverter control.
The primary objective of grid-forming inverter control is to maintain stable nominal voltage and frequency in the system irrespective of load changes. From Figure 10, voltage and frequency graphs of each of the phases, the results are consistent with the controller objective.
