An Improved Droop Control Strategy for Primary Frequency Regulation in Islanded Microgrids Using Distributed Energy Storage

The large-scale integration of renewable energy generation into the grid has led to increased frequency fluctuations in the power grid. Distributed energy storage systems, with their rapid response times, serve as a critical resource for primary frequency regulation. Traditional constant-droop control cannot adjust the...

A Multi-Objective Coordinated Fault-Riding Strategy for Grid-Forming Converters

To address the issues of excessive fault current, insufficient voltage support, and frequency oscillations in grid-forming converters during power grid short-circuit faults, this paper establishes a fault ride-through test model based on the principle of impedance voltage division and analyzes the fault transient chara...
