Grid impact of wind energy on isolated and remote power system

In this thesis, the impact of wind energy on isolated wind-diesel hybrid grid system and on remote grid connected wind farm were studied. In the case of the wind-diesel system a detailed mathematical model of Cartwright grid system is presented. The impact of a grid connected wind farm near St. Anthony, Newfoundland was also studied. Initially a pre-feasibility study was conducted to size the wind farm depending on wind data and local load data. In both cases voltage fluctuation and frequency variation in the grid power system due to the addition of wind energy were studied. Optimization software tool HOMER was used for pre-feasibility study for wind farm in St. Anthony. Detailed dynamic models of all system components and system parameters are provided in the thesis. MATLAB-S1MULINK was used for both cases for the dynamic modeling and system analysis. Finally, results are presented in both cases and future studies are proposed
