Abstract: This chapter presents the theoretical foundations and mathematical modeling of droop control strategies applied to decentralized power sharing in hybrid microgrids. The technique eliminates the need for complex communication infrastructure interconnecting the converters, instead utilizing local bus electrical variable fluctuations to achieve autonomous energy balancing. In the alternating current (AC) domain, conventional droop control linearly relates grid frequency deviation to active power for grid-forming sources (VCM), whereas inverse droop control is applied to current-injecting sources (CCM). Similarly, in the direct current (DC) domain, energy regulation is achieved through a direct relationship between bus voltage magnitude and the power processed by the source. It is demonstrated that the dynamic interaction among the various static converters—mathematically parameterized by their respective droop coefficients—ensures proportional, stable, and resilient load sharing, which is an essential condition for the operational reliability of modern distributed generation systems.
