Simulating attacks on power systems using NetSim

Electric power grid and Cyber Physical Systems (CPS)

  • The electric power grid (EPG) or smart grid is a critical infrastructure at high risk of cyber-attacks
  • At its core are cyber-physical systems (CPS), that integrate communication and computational technologies to interact seamlessly with the physical world.
  • Key CPS components like automated control systems, remote terminal units, PLCs, and IEDs are all connected to one another over a communication network.

Why choose NetSim for your cyber-physical testbed?

  • Security of CPSs can be improved by using a testbed to replicate power systems operating conditions and evaluate grid operation under maliciously constructed scenarios.
  • Hardware testbeds are costly, inflexible, hard to scale and demand safety considerations. Software testbeds overcome these difficulties and can function as digital twins.
  • A software testbed generally comprises of a power system simulator and a network simulator. The former models all the power electronics devices, power transmission and distribution while the latter models the communications network.
