What are crosscurrents in electrical power systems?

Crosscurrents in electrical power systems refer to the situation where multiple generators or sources of power are interconnected and sharing a load, yet they are operating at different output voltages. This discrepancy results in unwanted current flow, or crosscurrents, between the generators. Such currents can cause inefficiencies and power loss as the generators compete to supply power to the load at differing voltage levels.

This phenomenon can lead to instability in the system, as the generators attempt to balance the load without being perfectly synchronized. This not only creates operational challenges but also increases wear and tear on the equipment involved. Understanding crosscurrents is important for the design and operation of stable electrical power systems, where the goal is to ensure that all generators operate efficiently and harmoniously without significant interaction that can lead to losses.
