What is the term for automatic sharing of kW and kVAR power among paralleled AC power sources?

The term for automatic sharing of kW (active power) and kVAR (reactive power) among paralleled AC power sources is "Load Sharing." This term specifically refers to the process by which multiple generators or power sources work together to distribute the electrical load evenly.

In practical applications, when several generators are paralleled, it is crucial to ensure that they share the load proportionately according to their capacity. Proper load sharing enables efficient operation, minimizes wear on the equipment, and ensures that if one source fails, the others can compensate without overloading any single unit. Responsibility for active power falls under load sharing as generators adjust their output to meet the demands of the electrical system.

The other choices relate to different concepts within electrical systems. Power Transfer does not capture the aspect of multiple sources managing the load collectively. Energy Distribution is a broader term that could refer to various ways energy is transmitted but lacks the specificity toward the interaction between paralleled sources. Reactive Power Control, while it deals with managing kVAR, does not encompass the overall sharing of both active and reactive power among generators.
