Load Tracking Enhancement of a Grid Connected SOFC System Using an Advanced Controller in Real Time.

Modeling, measurement and control are the most important aspects, for making any renewable source to be in synchronism at the earliest with the utility grid during any load demand power change. This is to put minimum stress at the grid during load change as per the latest grid-code. Therefore, in this paper an efficient and rugged active power controller based on ANFIS has been implemented for improving the load tracking of grid connected static renewable source i.e. SOFC. Additionally, this controller is subjected to the constraint that the fuel utilization factor of the SOFC should stay within safe limits. The comparison of this proposed controller shows superior performance in contrast to conventional integral controller. The results have been verified in real time environment provided by OPAL-RT’s simulator through hardware-in-loop.
