Abstract

The main objective of this thesis is to serve as a guide, so readers are able to learn about microgrids and to design simple controllers for different AC microgrid applications. In addition, this thesis has the objective to provide examples of simulation cases for the hierarchical structure of a basic AC microgrid which can be used as a foundation to build upon, and achieve more complex microgrid structures as well as more sophisticated power-converter control techniques.

To achieve these objectives, the modeling of voltage source converters and control design in the z-domain are presented. Moreover, the implementation and transient analysis of the power-converter operating modes are executed through MATLAB/SimulinkTM simulations. Then, an energy management case for the central controller of the AC microgrid is performed utilizing real-time simulation tools, Typhoon HIL software and hardware devices in addition to Texas instruments digital signal processors as local controllers.
