Challenge and objective

  • The high dependence of power systems on Information and Communication Technologies establish new interdependencies and sources of failures that need to be properly analysed.
  • A new modelling approach is proposed for analysing the impact of communication failures in a smart grid monitoring scenario, with a specific focus on 5G implementation.

Work performed

  • A stochastic activity network model of the power Cyber Physical System was implemented.
  • Dependability metrics are analysed through a case study, with different state estimation approaches, rain regions and repair strategies.

Significant results

  • Analyses show that the radio channel is the major source of estimation error.
  • Factors such as fading and rain conditions, may affect the accuracy of state estimation significantly.

Impact for distribution system innovation

  • Modelling and simulation of interdependencies between ICT and power system are fundamental in smart grid design.
  • The close to ideal behaviour of 5G-URLLC enforces the prospect of future adoption for smart grid monitoring.
