An Improved Electric Spring Topology Based on LCL Filter
IEEE transactions on power electronics, 2022Electric spring (ES), which has been widely discussed in recent years, is a new demand response method. By adjusting the power of noncritical load (NCL), ES can adaptively improve power quality of the grid containing a high proportion of renewable energy

Regions of Active Damping Control for LCL Filters
IEEE Transactions on Industry Applications, 2012The control of a grid connected voltage source inverter (VSI) with an LCL filter is a very challenging task, since the LCL network causes a resonance phenomenon near to the control stability boundary. While many active damping methods have been proposed to overcome this issue, the role that PWM transport delay plays in the effectiveness of these ...

Filter-Based Active Damping of Voltage Source Converters With $LCL$ Filter
IEEE Transactions on Industrial Electronics, 2011Pulsewidth modulation (PWM) voltage source converters are becoming a popular interface to the power grid for many applications. Hence, issues related to the reduction of PWM harmonics injection in the power grid are becoming more relevant. The use of high-order filters like LCL filters is a standard solution to provide the proper attenuation of PWM ...

Backstepping control for active power filter with LCL filter
2nd IET Renewable Power Generation Conference (RPG 2013), 2013Active power filters are widely applied in power system to deal with distorted currents caused by nonlinear loads. As the active power filter (APF) with LCL filter is a serious nonlinear system, conventional control methods cannot have satisfactory performances. A nonlinear control method, backstepping control for active power filter with LCL filter is

Comparative analysis of the selective resonant LCL and LCL plus trap filters
2014 International Conference on Optimization of Electrical and Electronic Equipment (OPTIM), 2014In this paper two promising LCL based filter topologies are evaluated against the well-known LCL with a damping resistor. The filters are designed for high power applications where the frequency modulation index is relatively low. The first topology is the selective resonant LCL filter which aim is to minimize the damping losses by bypassing the ...
