| dc.description.abstract | This thesis investigates the performance and potential enhancements of battery energy storage systems (BESS) for frequency regulation, focusing on the integration of a Virtual Synchronous Generator (VSG) controller with the battery. The research involves analyzing the
VSG-BESS model created in Matlab/Simulink and comparing its behavior with real operational data from Statkraft, a leading energy company.
The results highlight the effectiveness of the VSG controller in improving frequency stabilization. The VSG-BESS model demonstrates responsive behavior by adjusting power
output in response to frequency deviations. Although initial instances of overshoot and undershoot may arise, the system gradually attains stability, emphasizing the efficacy of the
VSG controller and battery in regulating frequency.
The comparison of the VSG-BESS model with real battery operational data from Statkraft
confirms the model’s performance and practical value. The close correspondence between
the model’s behavior and the observed data indicates its accuracy in capturing the dynamics
of frequency regulation, enabling better design and optimization of BESS.
In conclusion, this research highlights the significance of integrating VSG controllers with
battery energy storage systems for effective frequency regulation. The insights derived from
the study provide valuable guidance for future research and development projects aimed
at improving the performance and efficiency of BESS. By actively responding to frequency
deviations, BESS can play a crucial role in sustaining grid stability and ensuring efficient
operation, contributing to the establishment of sustainable and reliable power grids. | |
