Effect of Communication Failures on State Estimation of 5G-Enabled Smart Grid
Challenge and objective
- The high dependence of power system 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.
- 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.
- 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.
