Abstract
This chapter consists of two sections, ‘Load Response Characteristics of a Fuel Cell Microgrid with Control of Number of Units’ and ‘Dynamic Characteristics of a PEFC System for Individual Houses’. The dynamic characteristics and generation efficiency of a microgrid structured from 17 houses are examined in the 1st section. The characteristics of the power quality of a fuel cell microgrid, and the generation efficiency of the fuel cell are examined by numerical analysis. In the 2nd chapter, the method of determination of the control variables for a system controller, which controls the electric power output of a solid-polymer-membrane fuel cell system (PEFC) during electric power load fluctuations, is considered.
