摘要

The distributed energy storage unit (ESU) will be a key component against the intermittent and stochastic character of the renewable energy resource in the islanded DC microgrid. The vanadium redox batteries (VRB) are a promising ESU for microgrid applications. However, one challenge in devising an islanded microgrid with ESUs is synchronizing the state of charges(SOC) of the ESUs. This paper proposes a consensusbased distributed cooperative control for alleviating voltage fluctuation, prolonging battery lifetime, and improving battery efficiency simultaneously. Furthermore, the real-time equilibrium of injected and output power and the constraints of the SOC are considered to simulate a more reasonable condition. Finally, this paper employs numerical simulation methods to test the effectiveness of the proposed algorithm in a DC microgrid composed of six DERs.
