Abstract
This master's thesis provides a thorough investigation into the utilization of wind power in islanded operation along with solar power and power from energy stored in the battery. The data for wind speed and solar irradiance is taken from the Chalmers research wind turbine located at Björko. The research work uses MATLAB Simulink software for mathematical modelling and simulations. The wind turbine and solar panels models are designed according to real data of wind speed and solar irradiance for 24 hours and for 1422 seconds. Considering the load profile of an island, a battery model is designed indicating charging and discharging of the battery. A controller is also designed which makes decisions based on available power source and load to control the islandic operation. Different scenarios at different load conditions are studied to validate the results. The analysis and performance evaluation for islandic operation is carried out, considering various factors such as load consumption and power generation from available sources. After analysing the simulation results of wind, solar, battery models under variable load conditions, the performance outcomes and their accuracy is discussed. The designed system for islandic operation demonstrated and confirmed the efficient utilization of power from available resources for every instance over a period of 24-hours and a period of 1422 seconds.
