LCL 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 کاملLCL Problems on Grids
LCLs or locally checkable labelling problems (e.g. maximal independent set, maximal matching, and vertex colouring) in the LOCAL model of computation are very well-understood in cycles (toroidal 1-dimensional grids): every problem has a complexity of O(1), Θ(log∗ n), or Θ(n), and the design of optimal algorithms can be fully automated. This work develops the complexity theory of LCL problems fo...
متن کاملGrid Current Regulation of a Three-Phase Voltage Source Inverter With an LCL Input Filter
Many grid connected power electronic systems, such as STATCOMs, UPFCs, and distributed generation system interfaces, use a voltage source inverter (VSI) connected to the supply network through a filter. This filter, typically a series inductance, acts to reduce the switching harmonics entering the distribution network. An alternative filter is a LCL network, which can achieve reduced levels of ...
متن کاملResonant Characteristics Analysis and Suppression Strategy of Multiple Parallel Grid-connected Inverters with LCL Filter
The multiple parallel inverters have more than one resonant frequency influenced by many factors, which tends to result in stability and power quality problems. This paper develops the multiple input multiple output model of the grid-connected inverters system using the closed-loop transfer function. The influence factors of resonant characteristics are analyzed with the developed model. The an...
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...
