Research on multiple-loop Control Strategy of Microgrid usingthe Virtual Power Droop Characteristics
This paper is based on the two port power transmission model and analyzing of micro grid conventional droop control strategy. Then strong coupling of active power and reactive power have been found during the circuit presents the different state under conventional control strategy of. For the power coupling problems, a virtual power control strategy with coordinate rotation matrix through rotation orthogonal transformation has been explored, which completes power decoupling in coupling conditions. Meanwhile, multiple-loop control strategy of inverter is studied on the basis of using virtual power strategy. Finally, MATLAB/Simulink simulation studies on the proposed model, verify the validity of the results.
