It looks like the results presented here are based on a simulation model.
Displayed on the third page[1] of the paper is a diagram illustrating that the number of voltage violations remains relatively low from 0 through 5000, 10000, 15000, 20000 and 25000 heavy-duty vehicles simultaneously being charged. Then as we approach 30000 vehicles (and continue beyond), the number of voltage violations increases markedly.
Can anyone provide supporting information on what "voltage violations" are and how serious these are, and/or any theories about why there is a sudden increase in the number of them that occur at a certain (seemingly high, non-linear) number of vehicles-under-charging?

- upsidesinclude 5y agoThis is a rough shot... Voltage violations would relate to the allowable delivered voltage range and deviation extent/time. So, power distributors should deliver, through a transformer say 235V±10V and allowable deviation might be some number of cycles (2? No idea) The real collapse arises when the power demand reaches the limits of the distribution leg. Maybe the local substation is rated at 1 GW. As the number of loads grows in a step-wise manner the components of the system reach capacity and voltage reduction occurs as amperage and power output is increased
