| ln order to improve the static and dynamic performance of converter for micro-grid energy storage, a double
closed-loop control method of feedforward decoupling and grid voltage oriented was proposed. This method used the
mathematical model of three-phase voltage source converter in the ( d, q) coordinate system and basing on the
synchronous rotation vector of grid voltage orientation. The inner current loop used feedforward decoupling direct current
control method to decouple the active and reactive current. It improved the tracking speed and precision of the inner
current loop, and also accelerated the response speed of the outer voltage loop. Simulation results show that the converter
system has good response speed, low current harmonic. stable DC side voltage and small ripple voltage, and it also can
work bidirectionally in unit power factor. So the control method is feasible and effective .and it has reference value for
application. |
