A Harmonic Compensation Strategy for Grid-connected Inverter with LCL Filter
LCL filter has the characteristic of prompt attenuation over the high-frequency range, but the thirdorder control system exits the resonance problem. Nonetheless, the inherent non-linear characteristic and dead-time effects of switching tubes, along with the DC-side voltage secondary pulsation and grid harmonic pollution, arouse a wealth of low-order harmonics injected which is tough to be filt...
متن کاملLCL Filter Design and Performance Analysis for Grid Interconnected Systems
-The use of power converters is very important in maximizing the power transfer from renewable energy sources such as wind, solar, or even a hydrogen-based fuel cell to the utility grid. A LCL filter is often used to interconnect an inverter to the utility grid in order to filter the harmonics produced by the inverter. Even though there is an extensive amount of literature available describing ...
متن کاملThree-phase LCL-filter for Grid-connected Inverter Using Cooperative Bacteria Foraging Optimization
This paper establishes an LCL-filters design and control for three-phase grid inverter. The crucial object is to conquer optimum damping with a required system control bandwidth for the LCL-filter. This control technique is achieved by using Bacteria Foraging Optimization. Mathematical analysis has been introduced to investigate the steady-state and dynamic performances of the overall system. T...

متن کاملRipple Current Analysis of Three-level Inverter based on SVPWM and Design of LCL Filter
Three-level gird-connected converter is used more and more widely in renewable energy generation system. At the same time LCL filter is also widely utilized in order to achieve lower current harmonic. However, current research about LCL filter is mostly aimed at two-level inverter. The study involving multilevel inverter is much less. When using space vector pulse width modulation, Current tran...
