Cybersecurity challenges and standards for smart power grids
Cybersecurity in Power Grids: Standards and Research Challenges
Cryptography and Security
Summary
Power grids that use smart technology need strong security to keep electricity flowing safely. This paper explains how cybersecurity in these grids is different from typical computer systems because power grids combine both IT (information technology) and OT (operational technology). It discusses the risks at substations where power is controlled and describes important international rules that help protect these systems. The paper also looks at current research, including how artificial intelligence can help spot cyber threats.
What this means in practice
- •For power grid security teams: Adopt and implement international cybersecurity standards tailored for both IT and OT components in smart grids to reduce risks.
- •For industrial control system engineers: Use insights about substation threats and AI-driven detection methods to improve control system security and anomaly response.
A survey. It maps existing work.

Abstract
This paper examines Smart Grid cybersecurity, emphasizing the critical distinctions between IT and OT environments. It analyzes grid architecture, substation threats, and key international standards, specifically IEC 62351, IEC 62443, and ISO 27001. Finally, it overviews latest research trends, including AI-driven threat detection.
