Development of an LCL filter for a residential Microgrid system

2015 International Conference on Advances in Electrical Engineering (ICAEE), 2015
Energy crisis is becoming one of the major challenges in today's world due to increased energy demand and at the same time decreased energy resources. Energy from renewable sources can never be exhausted. They cause less emission and therefore stand out as a potentially viable source of clean and limitless energy.

Regenerative AC electronic load with LCL filter

2012 10th IEEE/IAS International Conference on Industry Applications, 2012
This article present the design and implementation of a regenerative AC electronic load with LCL filter. The electronic load is composed by a current controlled rectifier, which drains from the equipment under test (EUT) the desired current profile, and a current controlled inverter connected to the grid, which is responsible for power regenerating ...

Spread Spectrum Modulation for LCL Filter Design

2019 20th International Symposium on Power Electronics (Ee), 2019
The LCL filter is often the bulkiest component in grid-tied converters, which is designed to satisfy the grid harmonic standards such as IEEE519. To reduce the filter requirement, application of the spread spectrum modulation (SSM) to LCL filter design is investigated in this paper.

Design and control of an LCL-filter based three-phase active rectifier

Conference Record of the 2001 IEEE Industry Applications Conference. 36th IAS Annual Meeting (Cat. No.01CH37248), 2002
This paper proposes a step-by-step procedure for designing the LCL filter of a front-end three-phase active rectifier. The primary goal is to reduce the switching frequency ripple at a reasonable cost, while at the same time achieving a high-performance front-end rectifier (as characterized by a rapid dynamic response and good stability margin).

Demystification of Active Damping Design for Three Phase LCL Filters

2019 IEEE International Conference on Industrial Technology (ICIT), 2019
Passive filters are inevitable for power electronic converters with grid coupling. In this context LCL filter topologies are a recognized cost and space reducing alternative to single coil solutions for grid current harmonic attenuation. Since this type of filter represents a third order plant, a simple PI controller can cause instabilities once ...

Sensorless operation of an Active Front End converter with LCL filter

2014 IEEE 23rd International Symposium on Industrial Electronics (ISIE), 2014
In this paper sensorless control method fora an Active Front End (AFE) converter is presented. Developed algorithm is based on Voltage Oriented Control (VOC), extended by additional Voltage Dips Compensation (VDC) module. Moreover improved Virtual Flux (VF) estimator based on SOGI-QSG for LCL filter has been shown.

Deadbeat Repetitive Control for a grid-connected inverter with LCL Filter

2019 IEEE 15th International Conference on Control and Automation (ICCA), 2019
In order to improve the quality of the power injected into the grid, a deadbeat (DB) control strategy based on weighted average current with plug-in repetitive control (RC) scheme is proposed for a grid-connected inverter with LCL filter. Firstly, we calculate weighted average current of input and output current of the LCL filter, and use this variable

Investigation on control strategies for LCL-filtered voltage-source converter

2012 IEEE International Symposium on Industrial Electronics, 2012
The grid-connected VSC system with LCL filter has resonance problems which will magnify the harmonics near the resonant frequency and result in a low stability margin and complex design of current regulators. In this paper, a novel control strategy is proposed by introducing the feedforward compensatory controls of state variables and grid voltage ...

Active damping of LCL filters

Grid-connected voltage source converters (VSCs) frequently implement third-order LCL switching ripple filters due to their superior high-frequency harmonic attenuation and compact sizing compared to standard L or LC filters. However, LCL combinations introduce severe resonance peaks that threaten control loop stability.

An integrated unit of LCL filter for grid-connected inverter

2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015
In order to further increase the power density of the grid-connected inverter, a passive integrated unit is proposed by combining two inductors and one capacitor of the LCL filter in this paper. For saving the volume and the height of the three passive components, the planar PCB (Printed Circuit Board) integration technique is used.
