Co-simulation

Both DynamicSimulation and ContingencyAnalysis are capable of exchanging scalar signals with other GridKit instances over ZeroMQ. These examples showcase this functionality in the following ways:

• Simple three-bus / two-bus network simulation.

• IEEE39 network bifurcation with one GridKit instance running most of the grid and another simulating a large generator and its dependents.

Running the examples

These examples may be in the following way:

sh /path/to/build/examples/PhasorDynamics/CoSimulation/run_cosim.sh \
    --case ieee39

The available cases are two-bus, three-bus, ieee39, and ieee39-contingencies. Ensure either the executables are on your PATH or that you specify them with --dynamic and --analysis. By default, the script uses a unique IPC endpoint. Use the --endpoint flag to override this.

Building

Enable SUNDIALS, GridKit_ENABLE_ZMQ=ON. Build GridKit normally otherwise.
