A converter control strategy based on droop control in distributed generation systems

The integration of large-scale renewable energy makes the power system face challenges, and the micro-grid is one of the important research directions for utilizing new energy. The development of distributed power has alleviated grid pressure to some extent, but there are new problems in electronic power systems. In the micro-grid, the power distribution control between parallel distributed power sources generally uses voltage droop control technology. The key to the technology is the coordinated control between multiple power converters, which requires the bus voltage and frequency to be within the rated range and the load power to be properly distributed to ensure safe and reliable operation of the power system. This paper proposes a control strategy that can make the characteristics of the grid-connected converters excellent, and verify them by Matlab/Simulink to prove the feasibility of the strategy.
