Cost effective MICRO-CHP sizing

This paper provides an overview of three operating strategies used in microCHP systems. The paper adopts the conventional control strategies for a fuel cell based microCHP system in order to determine the optimal sizing of the system. The effect that the operating strategy has on running cost and optimal sizing of the microCHP system is highlighted by way of examples in which heat-led control, electricity-led control and cost-minimizing control are examined using load profile data of a typical Danish Family household.
