Role of Micro Sources within Micro Grid

Microgrid is a grid which helps to provide the generation in case of Grid failure. Microgrid is a new concept in the arena of green power generation, which is substantially attracting many researchers´ interest due to its potential to extend the applications of the distributed generations, especially the renewable energy. Microgrid is a low voltage electrical network with small distributed generators, energy storage devices, controllable loads & protection. A MicroGrid can increase the reliability of energy supplies by disconnecting from the grid in the case of network faults or reduced power quality models for the main microsources/non conventional energy sources including Wind Turbines, Diesel Generator and fuel cells are properly established, in addition to the basic models of the power electronics interfaces being given simultaneously. This project emphasizes modelling & simulation of a Microgrid to account for both the transient and steady-state system characteristics; MATLAB/Simulink is used for the simulation, which can simulate both the steady and dynamic characteristics of the three-phase Microgrid. The result shows that there is an increase in power generation when the microsources/ non conventional energy sources connected within Microgrid which helps in different applications and also in case of grid islanded mode.
