This work introduces a bilinear formulation for microgrid operation control that finds optimal power setpoints and droop gains on timescale of minutes by solving a finite horizon optimization problem.. This work introduces a bilinear formulation for microgrid operation control that finds optimal power setpoints and droop gains on timescale of minutes by solving a finite horizon optimization problem.. In this work, a real time decentralized droop controller is implemented for an islanded DC microgrid to enhance the voltage regulation at the DC bus and current sharing efficacy between the sources subject to load transients. A novel control strategy is presented in which the conventional droop. . The optical storage DC microgrid, a novel distributed energy system, strives for efficient, dependable, and eco-friendly energy utilization. Within this microgrid, precise control and balanced regulation of the battery's state of charge (SOC) play a crucial role in ensuring system stability and. . However, using adaptive droop gains for grid-forming units allow to shape power sharing in presence of fluctuations, enhancing flexibility while maintaining safe microgrid operation, particularly under uncertainty.
