Research on the Control of Distributed Power Grid-Connected Inverter

Abstract:

Based on voltage space vector modulation, a distributed power grid-connected inverter (DPGCI) utilizing double loop control strategy is researched, the system is able to feedback power to grid with constant power and unity power factor. the static and dynamic performance is good. Firstly, a mathematical model of inverter system in two-phase synchronous rotating coordinate is built, based on this, a outer power loop and inner current loop control strategy is proposed, realizing the independent control of active and reactive power. Experimental results show the correctness and validity of the control strategy.
