Renewable energies are considered to be a significant part of the energy mix to assist the existing electricity demand and the future of electrical generation. Electrical power simulation software is increasingly being used to answer and determine the source of potential problems in the actual power system. To have a better understanding of an electrical power system, it is essential to validate all the components through simulation within an environment that allows accurate modeling of all power system components. This research presents modeling and analysis of an actual grid-connected solar-wind hybrid system at University of Northern Iowa campus in Cedar Falls, Iowa. A number of simulation studies were carried out in MATLAB/Simulink using the SimPowerSystems toolbox. This research covers simulations of normal operation of the actual gridconnected solar-wind hybrid power system, then compares the results to three case studies; (a) Case Study I: Analysis of PV terminal voltage fluctuations due to source and load changes, (b) Case Study II: Analysis of wind turbine terminal voltage fluctuations due to wind changes and (c) Case Study III: Analysis of voltage distortion at the utility interface. Each simulation case concentrates on the variation in voltage magnitude, sag and swell, continuous voltage operating range and transient voltage concluding with discussions of the problems that arise during fault operations.
