A DROOP CONTROL BASED PROPOTIONAL POWER SHARING METHOD FOR DC MICROGRIDS WITHOUT COMMUNICATION
Niğde Ömer Halisdemir Üniversitesi Mühendislik Bilimleri Dergisi, 2020 Although DC microgrids are getting popular, load sharing is still an unsolved obstacle for widespread operation. Conventional droop method which is one of the most preferred load sharing method partially manages load sharing however this is related to ...

Distributed Adaptive Droop Control for DC Distribution Systems [PDF]
, 2014 A distributed-adaptive droop mechanism is proposed for secondary/primary control of dc Microgrids. The conventional secondary control, that adjusts the voltage set point for the local droop mechanism, is replaced by a voltage regulator.
