Power Supply Synchronization Without Communication
The authors consider the synchronization of power supplies in an isolated grid with multiple small-to-medium power sources. They show how to achieve a coordinated or synchronized behavior by imposing suitable dynamical behaviors to the controlled converters that interface each power source with the local power bus, without any explicit exchange of information among the power supply units. This approach avoids the need for an independent communication network and therefore improves the overall system reliability. The method proposed to achieve synchronization does not rely on the common approach of mimicking the dynamical behavior of interconnected synchronous generators.
