Three-phase LCL-filter for Grid-connected Inverter Using Cooperative Bacteria Foraging Optimization
نویسنده
چکیده
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. The proposed control method is using one set of current sensors for feedback control only. The proposed system is simulated and results are demonstrated that bacterial foraging optimization is a skilful clarification for implementing the best parameters of LCL-filters and PI current controller. Results support the proposed technique and highlight its practicability. Key-Words: LCL-filter; grid-connected inverter; bacteria foraging optimization

The Design of a New Double Loop Controller For Simultaneous Adjustment of Input and Output Voltages of Single-Phase Grid-Connected Inverter
Although LCL filters are used widely in the grid connected inverters to reduce high-orderharmonics, such a system increases system order and therefore sustainable design of closed-loopcontroller system will be complicated. Recently, the single-loop control strategy has beensuggested for L or LC filter based grid-connected inverters. However, the use of single-loopcontrol directly in LCL filter-...
متن کاملAn LCL-filtered Single-phase Multilevel Inverter for Grid Integration of PV Systems
Integration of the PV into the electrical grid needs power electronic interface. This power electronic interface should have some key features and should come up with grid codes. One of the important criteria is the quality and harmonic contents of the current being injected to the grid. High-order harmonics of the grid current should be very limited (lower than 0.3% of the fundamental current)...
