摘要：

When traditional droop control is used in microgrid, there are many disadvantages, such as slow speed of dynamic regulation, uneven distribution of micro source power, unstable frequency and voltage, etc. To solve the above problems, a segmented dynamic adaptive droop control strategy is proposed. The droop coefficient is increased by piecewise droop control to improve the dynamic response speed of the system. The droop coefficient is adjusted by dynamic droop control to improve the power distribution effect. Adaptive droop control moves the droop curve to maintain frequency and voltage stable. Simulation and experiments are carried out on the above control strategies. The results verify the rapidity, accuracy and stability of the improved droop control strategy. © 2019, Power System Protection and Control Press. All right reserved.
