主 题：Multi-bus microgrid Distributed generation Grid-tied converter Harmonic compensation control
摘 要：This paper proposes a novel approach to compensate buses voltage and current harmonics through distributed generation(DG)interfacing converter in a multibus *** control approach of each individual DG unit was designed to use only feedback variables of the converter itself that can be measured *** the proposed approach,the adjacent bus voltage is indirectly derived from the measured DG converter output voltage,DG line current and line impedance.A voltage closed-loop controller and a current closed-loop controller are designed to achieve both functions of DG real power generation and harmonics ***,the traditional harmonic measurement devices installed at the bus as well as the long distance communication between the bus and the DG converter are not *** proposed approach can compensate the current harmonics,mitigate the buses voltage distortion and enable the customer devices to be operated in normal conditions within the multi-bus microgrid,and meanwhile relieve the burden of power quality regulator installed at the point of common *** simulations and experimental results are presented to show the operational effectiveness of the proposed approach.
