High-Frequency AC Integration: A Critical Analysis on the IEEE-33 Bus Standard System

As the demand for electrical distribution systems increases due to advancements in distributed generation (DG), energy storage, electric vehicles, and industrial upgrades, the necessity for efficient and manageable grid operations becomes crucial. A comprehensive grid restructuring is needed to tackle these challenges, ensuring effective power transfer, reducing losses, and maintaining existing infrastructure. One promising solution is the implementation of high-frequency AC (HFAC) technology, which operates at frequencies higher than the conventional 50-60 Hz power grid. This paper presents a standardized 33-bus High-Frequency AC testbed to fill a gap in the literature. Case studies using the 33-bus system demonstrate the benefits of integrating HFAC technology into current networks. Results from the testbed, which comply with international guidelines for both balanced and unbalanced loads, confirm the HFAC system’s compatibility with existing power infrastructure. MATLAB simulations support HFAC’s practicality by showing enhancements in power quality, voltage stability, power flow, and DG integration. Additionally, the study highlights the potential for downsizing components due to improved rating efficiencies. These results emphasize HFAC’s capability to integrate smoothly with present infrastructure and its potential as a sustainable advancement for power systems.
