Synchronous Generator Modelling and Analysis for a Microgrid in Autonomous and Grid Connected Mode

Abstract

Distributed generation is constructed on the basis of decentralized generation of electricity close to consumption sites using Distributed Generation (DG) sources. An optimized way to utilize the emerging potential of the distributed generation is to consider generation and its associated loads as a subsystem called "microgrid". A microgrid comprises of multiple DG units in close electrical proximity to one another. During disturbances the generation and the corresponding loads can separate from the distribution system to isolate the microgrid"s loads from the disturbance and thereby maintaining the service without harming the integrity of transmission grid. This work elaborates in detail the modeling and analysis of the Synchronous Generator that is connected to the microgrid which is the considered as one of the DGs. The modeling has been done in MATLAB/SIMULINK by integrating all the sub-models which include exciter, turbine and governor and the electrical part.
