ABSTRACT

Distributed power control is a prerequisite for microgrid control and reliable operation. In this paper, a DROOP control method of distributed power supply is designed. According to the basic principle of Droop typical micro power control method, the simulation model is established by Matlab/Simulink simulation environment. The correctness and validity of each model are verified by simulation. It can be seen from the simulation results that the inner loop of the current can achieve the different tracking regulation. The dynamic response of the outer ring is better, both of which can make the system better stability; Z(S) is in the low frequency band, frequency, which can be very good to achieve Droop control in the sagging characteristics, while there will be a certain ability to suppress the harmonic, and finally through the analysis, it proved the control parameters of the rationality of the value and effectiveness.
