“…The semiconductor switches are controlled by the pulse width modulation (PWM) technique [7]. Using the non-linear control theory, the inverter output voltage vector, ⃗ = [ ] (measured in relation to ), can be approximated by its average value within the switching period, resulting in an equivalent linear model [8], [9]. Using this approximation, the inverter output current vector, ⃗ = [ ] , is obtained by…”

The microgrid structure needs, at least, one power converter able to work as a grid-forming converter. In fact, such converter must present two operations modes: grid-forming when the main grid is outage; grid-following (or grid-supporting) when the main grid is available. This paper presents a control scheme that allows this microgrid power converter operates in both operations mode (grid-forming and grid-supporting). Besides, the transient response during the operation mode changes occurs smoothly. Results of simulations and experiments are presented to prove the feasibility and performance of the proposed control scheme.
