International Journal of Power System Operation and Energy Management


This paper presents analysis of control techniques of a converter fed microgrid in grid connected mode and islanded mode of operation. Here two control strategies are discussed , one for grid connected mode and the other for islanded mode of operation. In grid connected mode of operation the DG inverter system works in constant current control mode, and provide preset power to the grid, while in islanded mode of operation the DG inverter system goes to voltage control mode. Voltage control mode is simple and has a low number of control loops.
