Dynamic Modeling of Microgrid for Grid Connected a
no vote
Microgrid is defined as the cluster of multiple
distributed generators (DGs) such as renewable energy sources
that supply electrical energy. The connection of microgrid is in
parallel with the main grid. When microgrid is isolated from
remainder of the utility system, it is said to be in intentional
islanding mode. In this mode, DG inverter system operates in
voltage control mode to provide constant voltage to the local load.
During grid connected mode, the Microgrid operates in constant
current control mode to supply preset power to the main grid.
