To develop a distributed secondary control scheme that restores DC bus voltage to nominal levels while maintaining accurate power allocation among distributed generators in islanded DC microgrids.
Formulated a secondary control layer that relies only on localized neighboring communication and DC bus voltage feedback rather than global information.
Integrated pinning control to further simplify the architecture by routing DC bus voltage feedback to only a single distributed generator.
Validated performance through MATLAB Simulink simulations and an experimental hardware prototype comprising two distributed generators.
Eliminated droop-induced DC bus voltage deviations, successfully returning bus voltage to its nominal value across varying load profiles.
Maintained precise power sharing among distributed generators using only local neighbor interactions and single-unit voltage pinning.
