Abstract

A control structure for a hybrid renewable energy source tied to a direct current (DC) motor is proposed. The energy system is composed by a Photovoltaic (PV) array as the primary power source and a Fuel-Cell (FC) as an auxiliary or secondary power source. The control system has been developed to guarantee motor speed regulation and maximum power generation of the energy sources under any environmental and load condition, for instance low irradiance levels or a high demand in the load torque. A simulation of the system using real environmental data is presented in this document.
