Abstract: With the large-scale integration of distributed generations, distribution networks face challenges such as excessive current flow and active regulation. This article proposes a regulation control strategy based on distributed generations group dispatch and control technology. The strategy employs a hierarchical approach, connecting the central station with provinces, regions, and end users, utilizing the controllability advantage of distributed generations. It enables centralized control of the interconnected distributed generations while allowing for local autonomy and collaboration in distributed energy. Through the distributed generations group dispatch and control module and combined with layered partition optimization, it mitigates fluctuations in current flow and overvoltage to support the safe and stable operation of the power grid.
