Dynamic modelling of microgrid with distributed generation for grid integration

Distributed energy sources are likely to play a vital role in small to medium scale in the existing grid. However integration of these sources towards formation of Smart Grid (SG) is the significant aspect of the study. Generally voltage source inverters are employed for interface with distributed system. This paper looks into the aspects of integration of distributed energy sources such as Photo Voltaic (PV) solar, wind and fuel cell at distributed level. In respect of this looking to the interconnection parameters for synchronized operation a control strategy to achieve required voltage profile. A mathematical model has been developed. This takes into consideration the dynamic variation of distributed sources and the parameters of grid system. The results of an integrated operation for the distributed operation for the distributed sources and the grid integration for both mathematical modelling and simulation in Matlab have been presented for the typical non-linear loads.
