ABSTRACT: A hybrid renewable energy system is described which consists of twelve photovoltaic (PV) panels and a wind
generator and can supply continuous electric power of kW. An Energy Management System (EMS) was developed for this
purpose in order to maximize the electric power produced using a maximum power point tracking (MPPT) method and
consists of Buck-type DC/DC converters controlled by a microcontroller. The main difference between the method used in this
system and other techniques used in the past is that the generated power controls directly the DC/DC converters, thus reducing
plexity of the system. The resulting system has high efficiency, lower cost and can be easily modified to handle more
energy sources. Experimental results show that the use of the MPPT control method may increase the output power of the PV
panels by as much as 15%. The energy produced by the renewable energy sources can be stored in lead-acid batteries for a
stable supply of electric power. The s
