Microgrids (MG) are emerging as a new paradigm for the integration of Distributed Generation (DG) assets. These novel grid structures present significant benefits to the Electric Power System (EPS). One of the most important benefits is the reliability improvement due to the capacity of stand-alone operation. Nevertheless, this stand-alone operation may bring some problems related to frequency control, especially in MG with many DG units connected through power electronics devices. In this case, the frequency control capacity and, in consequence, the stability margins are drastically reduced. This paper presents the design and implementation of a device and its control strategy for the frequency control of an ac microgrid using Proton Exchange Membrane Fuel Cell (PEMFC) and Supercapacitor Energy Storage (SCES).
