HYBRID WIND-SOLAR ELECTRIC POWER SYSTEM

This thesis based on modeling the PV/Wind hybrid system using ETAP program software in order to study the impact of this hybrid system on the transient stability and power flow in an existing grid.As renewable energy becomes more prevalent, more information on how different technologies will behave needs to be available. This thesis is based upon the combined use of solar and wind energy, in the hope to discover and determine to what extent the energy produced is capable of satisfying the energy demands. Combination of PV and wind renewable sources is made the advantage of using this system in regions which have higher wind speeds in the seasons that suffers from less sunny days and vice versa. This thesis based on modeling the PV/Wind hybrid system using ETAP program software in order to study the impact of this hybrid system on the transient stability and power flow in an existing grid. As one part of modeling the PV/Wind hybrid system, the system was controlled using ATmega16 microcontroller that sends signals to the different sources via a mechanical relay in order to control the combination of sources that needed to feed the load. Transient stability and load flow results were directly compared for different configurations of hybrid system. These simulation results ensured the effectiveness of the proposed PV/Wind hybrid system control strategy in following up the variations in load
