Energy cyber-physical system digital twin playground

A method for enhancing resiliency of a power system comprising a plurality of networked microgrids (NMGs), the method comprising:

• receiving, by a processor, data from a cloud server, the data comprising controller data and sensor data of the power system;
• generating, by the processor, in real-time a digital twin (DT) for the plurality of NMGs based on the controller data and the sensor data received from the cloud server, the DT comprising a physical dynamics model and a cyber dynamics model;
• monitoring, by the processor, operation of the plurality of NMGs of the DT;
• and
• taking, by the processor, corrective action to mitigate any attacks on an NMG of the plurality of NMGs of the DT,
• the taking of corrective action to mitigate any attacks on an NMG of the plurality of NMGs of the DT comprising:
• using a Luenberger Observer to construct and test multiple what-if scenarios to authenticate a healthy desired control state of the DTI;
• and
• returning the DT to the healthy desired control state.
