No Load Voltage Rise with more than one sources working

[itsEEE]

Is the following statement correct?
At no load or lightly loaded conditions, for a distribution system, where the lines lengths are in meters, the voltage at buses rises when we add new power resources in the same circuit.

if yes then please explain.

Even I have seen that the voltage rises on a particular bus of a network having no load conditions, on adding a new power source at any bus, considering small lines and negligible conductance.

Please help.

The no-load voltage output of the transformers is deliberately kept a little higher than the system rated voltage. This is to compensate at least partly, the transformer voltage drop as the transformer is loaded.
So, when the system is lightly loaded or not loaded, the voltage of the system will be higher and can be 105% or even more depending on the power system configuration and overall loading.

I am baffled why the voltage would be impacted by the units used to measure line length.

This portion of the forum prohibits homework questions. Can you tell us a bit more about your system you have observed? Adding new power sources in terms of generators may have a very different impact compared to adding additional transformers connected to the regional power grid.
