Impact of Data Centres on Power Grid Reliability

This technical report discusses the implications of data centres on the power grid, particularly in the context of increasing energy demands and the integration of renewable energy sources. It outlines the challenges posed by the growing energy usage of hyperscale data centres, which are becoming significant contributors to overall power demand. The report details the need for effective management strategies to handle variations in renewable energy, maintain grid reliability, and address congestion issues. Additionally, it presents the role of grid-interactive uninterruptible power supplies (UPS) in enhancing energy management and supporting the grid. The report emphasizes the importance of new grid connection requirements for converter-based loads and the necessity for compliance with standards such as Fault Ride Through (FRT) and Post Fault Active Power Recovery (PFAPR). It concludes by highlighting the potential of data centres to provide flexibility and system services, suggesting that their proper integration can mitigate risks and enhance grid stability.
