What type of power sharing involves multiple synchronized AC sources?

The correct choice refers to parallel operation, which is a method where multiple AC power sources are synchronized and connected to a common grid or network. In this scenario, multiple generators or AC sources operate together to supply power to the same load or system, providing benefits such as increased reliability, capacity, and efficiency.

When operating in parallel, each source not only shares the load but also contributes to voltage regulation and frequency stability of the overall system. Successful parallel operation requires precise synchronization to ensure that the voltage and phase angle of each source match before they are connected. This practice is commonly utilized in power plants and marine electrical systems, where multiple generators operate simultaneously to meet varying load demands.

In contrast, reciprocal power, distributed generation, and load shedding do not inherently involve the simultaneous synchronization of multiple AC sources. Reciprocal power generally refers to the exchange of electrical energy between two systems but does not emphasize synchronized operation. Distributed generation pertains to generating power from multiple small sources located close to load centers, but this doesn't necessarily imply that they are synchronized. Load shedding involves reducing load demand, usually for stability or safety reasons, and does not relate to simultaneous generation from multiple sources.
