A passive network is defined as a network that is totally dependent on the output of a voltage source, while a weak network is defined by a network that has voltage changing with power flow. My question is: a network with a voltage source, connected to a system through a cable, with a resistive load and an induction machine operating as a motor. Is this a passive grid or a weak grid? The induction machine is a motor, and hence no source.. and therefore I initially thought it was a passive grid if this was the load. But still, the operation of an induction motor is very similar to the operation of the induction generator, so maybe it is a weak grid system? I really appreciate any answers!
