abstract = "This chapter has firstly summarized the instantaneous power theory and its extension for the purpose of controlling voltage source inverters under unbalanced faults. Regarding the converters operating in grid-connected mode to feed a certain amount of active and reactive power to the microgrid, two groups of control strategies, namely flexible oscillating power control and flexible positive- and negative-sequence power control are reviewed together with the design of inner current controllers and converter current limitation methods. For the autonomous operation of the microgrid, the control of a voltage source inverter operating under an islanded mode to provide voltage amplitude and frequency references is briefly reviewed. To improve the short-circuit performance of such an inverter under unbalanced fault, the negative-sequence current control loop is implemented. This chapter is finally supported by the application of different control strategies in a typical microgrid setting followed by discussions on microgrid protection",
