Hybrid Power Stabilizer (HPS) for Mission-Critical Data Centers
May 21, 2026
Battery Energy Storage for Data Centers
AI workloads create power volatility that legacy data center architectures were never designed to handle. Prevalon’s Hybrid Power Stabilizer (HPS) actively stabilizes those load swings — helping protect uptime, equipment, and operational capacity at scale.
Your Power Architecture Wasn’t Built for AI-Scale Loads
AI and high-density compute have fundamentally changed the power demands on data center infrastructure. Traditional UPS systems provide ride-through, but they do not actively manage continuous load volatility or protect complex hybrid power systems.
- Rapid load swings: AI and GPU clusters can create synchronized, high-magnitude ramp events that stress frequency stability and voltage limits.
- Generator stress: Transient torque events can increase mechanical fatigue on synchronous machines, creating risk of nuisance trips and forced derates.
- Grid interconnection limits: High ramp rates and poor power quality can create compliance and disconnection risks.
- Hybrid architecture complexity: On-site generation, renewables, storage, and grid connections require coordinated real-time control.
Active Stabilization — Not Just Backup Power
HPS operates at the medium-voltage layer to absorb, dampen, and orchestrate load volatility in real time — before it impacts generators, interconnections, or sensitive IT equipment.
Instead of acting only as backup power, HPS transforms stochastic AI-driven load behavior into a stable, grid-ready power profile across grid-connected, islanded, and hybrid operating modes.
Core HPS Capabilities
- Millisecond-level response: Power electronics absorb rapid load fluctuations before they propagate through the system.
- Voltage and frequency stabilization: HPS helps maintain power quality during transient events.
- Generator protection: The system filters harmful drivetrain frequencies and absorbs transient torque events.
- Black start and islanding: HPS supports restart without grid power and enables resilient islanded operation.
- Peak shaving and load management: HPS smooths AI-driven demand spikes and supports more efficient energy use.
- Cybersecure control: insightOS™ provides secure, on-premise control aligned with IEC 62443 standards.
