Abstract

The uncertainties caused by renewable energy sources (RESs), droop control, etc. often undermine the performance of distributed DC microgrids. In this paper, we have investigated the functioning of a novel consensus-based secondary control strategy to achieve proportionate current sharing and voltage synchrony in a generalized networked multiple DC microgrid clusters with hybrid energy storage system (HESS) by compensating mismatches in droop coefficients, line resistances, etc. Alongside, frequency based power sharing and voltage regulation is achieved in a decentralized manner to circumvent load transitions. An optimal, event-based communication strategy has been designed for the sharing of state information with neighboring converters over limited bandwidth. Design procedure, stability analysis, performance under communication adversities are provided to help determine the suitability of the proposed technique. Finally, simulation results for different test-cases are presented to validate the efficacy and robustness of the proposed method.
