Maximum Penetration of Intermittent Renewable Energy in Southern Sulawesi System Based on Primary Reserve Constrained Unit Commitment

Sulawesi has high potency in renewable energy. Wind potency is used for generating electricity through wind power plants (WPP). Large penetration of WPP will affect the variability of net load curve. This study aims to determines the penetration level of WPP based on the unit commitment solution considering primary reserve. Maximum penetration level is determined by gradually increasing the WPP penetration level so that no feasible solution is found. This method was repeated with the consideration of battery energy storage system (BESS) technology. The result shows that the maximum penetration level for the weekdays curve and weekend curve are 30 and 34 peak load. With BESS, the penetration level can be increased up to 36 and 41 for the weekday and weekend load curves. © 2021 IEEE.
