Is there a way to change a generator's power output during dynamic simulation? I'd like to create a pilot signal, as in a pulse, and embed it in a generator and observe changes in the system during dynamic simulation.
Thanks
If you don't want to create a user defined model, a python-based hybrid simulation such as a phase shifter in front of an infinite gen could work.
A user-defined exciter model (in fortran) could control the terminal voltage of a classic-model generator in a single-machine infinite-bus setup. This SMIB simulates the network equivalent connected to the device under test. At every time step, this exciter's Voutput will follow the signal generator function in time. Any takers?
The easiest way to modulate the power of a fictive generator is to represent it with a negative load and change the load value during the simulation. You will then see how a pure power pulse affects the rest of the system.
How to modulate (sine function?) the P and Q of the negative load?
A sine function is of course more difficult. For that you need to write a user model that updates the load every time step.
