How are crosscurrents between parallel generators minimized if the bus voltage is low and the power factors (PF) are the same?

Raising the voltage to all units helps to minimize crosscurrents between parallel generators when the bus voltage is low and the power factors are the same. Crosscurrents occur when generators are connected in parallel but do not deliver the same current due to differences in voltage or power factor. By increasing the output voltage of all generators, their contributions to the bus can be better aligned, improving the overall system stability and efficiency.

When the voltage is increased uniformly across all generators, it reduces the potential for imbalances that can lead to crosscurrents. Additionally, with the power factors being the same, this uniformity in voltage supports a more equal distribution of load across the generators, further diminishing the risk of any one generator becoming overloaded or underloaded relative to its parallel partners.

Other options might address different issues but do not effectively provide a solution to minimizing crosscurrents in this specific scenario. For example, lowering the voltage or increasing the load on generators could create further imbalances, while reducing the output of one generator could exacerbate the issue by increasing the load on the remaining units, potentially leading to heavier currents than necessary.
