Droop Control Strategy of Microgrid Parallel Inverter Under Island Operation
Advances in intelligent systems and computing(2020)
Abstract
The microgrid is developed rapidly with the growth of the global energy Internet. The operating characteristics of inverter directly influence the stability and reliability of the microgrid system. We will analyze the operating characteristics of the inverter droop control matched with the voltage, frequency, active power, and reactive power of the microgrid. And then, the droop control strategy of microgrid parallel inverter in island model is optimized. Through the mathematical modeling and simulation using MATLAB/Simulink, the dynamic characteristics of voltage and frequency with change in the microgrid load in island mode are analyzed particularly. The correctness and effectiveness of the droop control strategy optimization of the parallel inverter of the microgrid are verified by the simulation results.
