Comparison on Control Strategies of Inverters in AC Microgrids
摘要
Abstract
Inverters are important devices in AC microgrids,and their control strategies are key issues on the safety,reliability, effectiveness,and economical operation of microgrids.From the viewpoint of frequency domain,a comprehensive survey and comparison is achieved on the fundamental and harmonic power control.In view of the fundamental power control of an inverter in the microgrid,Vf control and droop control are explained in detail for the islanded inverter,while the direct power control,direct voltage control,direct current control,and direct impedance control are fully summed up for the grid-connected inverter.With respect to the harmonic power control of an inverter in the microgrid,switching ripples suppressing,harmonic resonance damping,and compensating of low-order harmonic load current are discussed in depth.To integrate the multiple inverters in a microgrid,the coordination strategies by using centralized hierarchical control and decentralized multi-agent-based control are fully discussed and compared.Finally,the trends and future frameworks to control inverters in AC microgrids are also presented.关键词
