Power grids digitalization and cybersecurity
As power grids evolve with advanced automation and increased reliance on digital communication, they are becoming smarter and more efficient—but also potentially exposed to vulnerabilities. To address the challenges of digitalization and cybersecurity, we must account for the growing risks tied to increased connectivity and data exchange. The transition to Ethernet-based protocols and remote monitoring systems increases the risk of communication failures, such as latency issues, data corruption, desynchronization, and equipment misconfigurations. Our real-time platforms support cybersecurity testing and validation by replicating these risks in a safe environment. These challenges highlight the need for robust testing and validation environments to ensure grid stability and security.

Challenges
Safeguarding the grid against cyber threats
Beyond accidental failures, power grids are prime targets for cyber-attacks, including denial-of-service (DoS) attacks, man-in-the-middle (MitM) intrusions, ransomware incidents, and data spoofing. As digitalization and cybersecurity become central to power system operations, we enable utilities and researchers to stay ahead of emerging threats through advanced simulation cybersecurity capabilities. We empower power system professionals with cutting-edge real-time simulation platforms that integrate power system and communication network co-simulation.
This integrated approach supports cybersecurity simulation and helps teams carry out accurate cybersecurity testing for critical systems. This enables system operators and researchers to test vulnerabilities, develop resilient control strategies, and enhance grid security in a controlled, risk-free environment, ensuring safe and reliable power system operations in the face of digital threats.
