Chapter 11: Dynamic Characteristics of Power for PEFC Compound System Check Access

The method of determination of the control variables for a system controller, which controls the power output of a PEFC system during power load fluctuations, was considered. The operation was clarified for the response characteristics of power generation for setting the control variables of proportional action and integral action considered to be the optimal for the system controller. The power load pattern of an individual house consists of loads usually moved up and down rapidly for a short time. This Chapter investigates the relation of the control variables and power generation efficiency when adding change that simulates the load of a house to PEFC cogeneration. As a result, it was shown that an operation, minimally influenced by load fluctuations, can be performed by changing the control variables using the value of the power load of a system.
