Microgrid technology is poised to transform the electricity industry.In the context of commercial/domestic buildings and data centers, where most loads are native direct current, DC microgrids are in fact a natural choice.Voltage stability and current/power-sharing between sources within a DC microgrid have been studied extensively in recent years.DC voltage droop control Plush is known to have its drawbacks in that current or power-sharing is relatively poor.To eliminate this drawback, some have proposed to add a communication-based consensus control in addition to the primary voltage droop control loop.
The current Mountaineering - Accessoires - Fixations sharing performance is improved, however, the voltage deviation inherent in droop control requires a further, slower control to achieve voltage quality control.To overcome this complication, and reduction in response time, a low latency communication-based control technique that achieves proportional current sharing without significant voltage deviations is proposed in this work.The stability of the proposed control technique is compared to state-of-the-art using eigenvalue and transient analyses.The negative impact of communication delays on proposed control is discussed in detail.
