Overview

Investigates the impact of cyber attacks on the operation of HVDC systems, highlighting significant equilibrium shifts.

Key Points

  • The aim is to analyze how cyber attacks affect the stability and operating points of HVDC transmission systems.
  • Mapped control curves of two HVDC converters onto a common control plane.
  • Derived propositions for attack-induced switching of HVDC control strategies.
  • Conducted time-domain MATLAB/Simulink case studies to validate theoretical findings.
  • Found that linear characteristics of control curves can become quadratic or more complex under cyber attacks.
  • Demonstrated abrupt bulk power reversals and bifurcation-like behaviors with small measurement perturbations.
  • Provided a framework to help HVDC operators assess and mitigate risks from cyber threats.
