Digital Twin for Real-Time Security Assessment and Flexibility Activation in the Bornholm Distribution System
A new AI-powered Digital Twin prevents blackouts by coordinating solar and wind power in real-time.
A team of researchers has successfully implemented a real-time AI-powered Digital Twin for the Bornholm Island distribution system, a Danish grid with high renewable energy penetration. The system, detailed in a new arXiv paper, integrates live smart meter measurements and network topology to continuously assess grid security. It specifically monitors for voltage violations and thermal loading limits, which are common challenges as solar and wind power fluctuate. Crucially, the Digital Twin simulates potential equipment failures (known as N-1 contingencies) to predict and prevent blackouts before they occur.
When the system detects an impending violation, it doesn't just sound an alarm—it activates a solution. Using an optimization-based approach, the Digital Twin coordinates 'flexibility actions' across the network. This means it can automatically instruct distributed energy resources (DERs) to adjust their active and reactive power output to stabilize the grid. The results from the Bornholm test show this strategy effectively mitigates operational risks, transforming the grid from a passive infrastructure into an actively managed, self-healing system. This proves the viability of Digital Twins for ensuring the reliable operation of future, renewable-heavy power networks.
- The Digital Twin performs real-time security assessment using live smart meter data and network topology.
- It uses optimization algorithms to coordinate DERs and prevent voltage/thermal violations during normal and contingency scenarios.
- Tested on the real Bornholm Island grid, it successfully enhanced operational security and efficiency through automated control.
