ABSTRACT
The control of DC microgrids is a growing area of research. DC distribution networks present an effective solution to the integration of stochastic energy sources as renewable energy and renewable storages. A communication layer is required to exchange measured and estimated values for the secondary control loop. Faults and failures within the communication layer lead to malfunctions and divergence in system values. The control structure is presented using adaptive droop based secondary control for detection of communication islanding and stabilize the operation of the system. Recent years, more robust techniques and methodologies have been suggested to increase system resilience, but the communication islanding detection has not been addressed in DC microgrid at the multi-level control. This work, therefore, modifies the secondary level control to include a communication failure detection scheme that identifies communication islands within this network. Adaptive droop is employed to mitigate the effect of communication islands and regulate current sharing. The proposed scheme is verified using system-level simulations and analytical studies.
