Power sharing in microgrids with minimum communication control

Proportionate sharing of load changes in a microgrid without communication among the generators is a difficult problem. In this paper an exact power sharing algorithm is developed that uses an optimization-based technique to minimize the exchange of state information among the generators. To demonstrate the application of the developed framework we present simulation results for a system constructed using the data obtained from IEEE 14 bus system. Simulation results reveal that power sharing can be achieved using relatively few communication links among the generators.
