Power Hardware-in-the-Loop (P-HIL)
The Power Hardware-in-the-Loop components allow tansfering behavior of modelled systems like ev twin to real power flow on hardware. Depending on the type of model, two main concepts that are presented in the following pictures :
Current or voltage controlled concepts of P-HIL
In the current controlled operation the power amplifier's voltage measurement is integrated with a signal controlled voltage source into the HIL model. The connected model (e.g. PV system or electric vehicle) generates a current, which is sent as a reference to the power amplifier and closes the control loop.
In the voltage controlled mode (e.g. for grid emulation or battery emulation), the measured current is integrated with a current source. The connected model generates a voltage that is sent to the amplifier as a reference.
