The Stirling Microgrid Generator (SMG) is presented as an electrical power system that will be developed around a representative system as a means of focusing the design. The representative system is Margaret Loock Residence Hall at Milwaukee School of Engineering in Milwaukee, Wisconsin. Selection of a representative system defines the cost of energy sources, such as natural gas and electricity, the availability of natural resources, such as solar and wind power, and the government instituted regulations that affect the design of the SMG. A beta-type, free-piston Stirling engine driving a linear alternator is selected for use in the SMG system, which must be capable of generating a minimum of 120 kW at a minimum efficiency of 28% to serve as a practical alternative to macrogrid electricity generation. Core concepts of the microgrid and Stirling engine are covered and several key parameters in Stirling engine design are investigated as they relate to the SMG.
