Tightly coupled microgrid power systems strike a balance between maintaining the desired power quality and insuring a high utilization efficiency of large-nonlinear loads. This is of great interest to the US Navy. Application of large-nonlinear loads in microgrid power systems requires energy storage to serve as the power supply for the large-nonlinear load. Degradation of power quality caused by improper charging large-nonlinear load's energy storage will affect the normal operation of every electrical device inside it. The objectives of the proposed generalized framework for charging energy storage for large-nonlinear loads in a tightly coupled microgrid are to 1) mitigate the power impact of energy storage charging in order to maintain the desired power quality in microgrid power systems. and 2)ensure a rapid charging speed of the energy storage. In this research, the aforementioned objectives were pursued using both hardware and software solutions. The hardware solution involved selecting an optimal distribution architecture that can ensure fast charging of energy storage without degradation of power quality. The software solution involved the development of a comprehensive control strategy that can coordinate power generation controls and energy storage charging. The goal of developing a generalized microgrid scale framework for charging an energy storage for large-nonlinear load module was thus achieved. This achievement can contribute to the application of large-nonlinear loads in tightly coupled microgrid power systems. / A Dissertation submitted to the Department of Mechanical Engineering in partial fulfillment of the requirements for the degree of Doctor of Philosophy. / Spring Semester, 2015. / November 12, 2014. / generalized predictive control, large-nonlinear load, microgrid, power quality / Includes bibliographical references. / David A.
