Resumé

In this work a dual-loop control strategy is applied to a highly distributed architecture of PV/battery- based DC microgrid, suitable for swarm electrification of developing regions. Typically, in such schemes, resource sharing among the spatially dispersed PV generation and battery storage resources is enabled via communication based control methodologies, which adds cost and complexity to the overall system. Alternately, a communication-less and decentralized control methodology is proposed which utilizes inner loop current control and outer loop voltage droop (V-I droop) control for the coordinated resource sharing among the distributed resources. Various scenarios of power sharing among the contributing households are evaluated and the efficacy of the proposed control scheme is validated through simulations on MATLAB/Simulink. Results show that the proposed decentralized control strategy is capable to ensure stable and coordinated operation without any dedicated layer of communication among the dispersed generation/storage resources.
