Abstract
At present, the direct current (DC) micro-grid based on the solid oxide fuel cell (SOFC) can supply the power to the external load independently. Despite an adequate and steady supply of the electricity to the external load, the high efficiency and avoiding fuel starvation is other points for the attention. In this paper, a control method of the SOFC-based DC micro-grid has been proposed, which can avoid the fuel starvation when the external load power increases This method adopts the optimal operating points (OOPs) to obtain the maximum efficiency, and then a novel time-delay control algorithm based on the system electric current is designed to avoid the fuel starvation. All simulation results demonstrate that the proposed method is feasible, which can effectively solve the fuel starvation problem. What's more, the output efficiency can be up to 40%, which can get the high efficiency of the power supply. The works in this paper can provide the reference for other similar systems to solve the fuel starvation problem.
