Voltage and frequency control

The focus of this paper is on studying power control for Interlinking Converters (ICs) to maintain stable voltage frequency on both AC and DC sides for a hybrid AC/DC microgrid in standalone mode, as well as the balance of active and reactive power. The control method also enhancing the resilience of the hybrid AC/DC microgrid during sudden load increases or power source failures in the AC and DC subgrids.

This paper presents a voltage and frequency adjustment method based on fuzzy logic to minimize voltage and frequency deviation to improve power quality in microgrids. This controller includes a Droop controller combined with fuzzy logic, the fuzzy logic block will control to change in the slope of the Droop characteristic curve when the load changes.
