Grid impedance detection via excitation of LCL-filter resonance

, 2005
Inverters adopted in distributed power generation, active filter and UPS are often connected to the grid through an LCL-filter. The impedance of the LCL-filter has a typical frequency spectrum with a resonance peak.

A Generalized Analytical Tuning Approach for Model Predictive Controlled Grid-Tied Converters Under Wide Range of Grid Inductance Variation

IEEE Access, 2022
In medium-high power applications, the LCL is the preferred filter topology to attain efficient power conversion. The filter provides a high damping attenuation of -60 dB/decade above the resonance frequency at the cost of a higher order plant, complex ...

Box–Behnken optimization and ANN‐ANFIS integrated modelling for transesterification using thermally activated basic oxygen furnace slag catalyst

The Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5991-6006, November 2026.
Abstract Global energy demand and environmental concerns have intensified the search for renewable and sustainable energy sources. This study thus, focuses on optimizing the transesterification process of waste cooking oil (WCO) using thermally activated basic oxygen furnace slag catalyst calcined at 850°C (BOF 850). The optimization and modelling were

Deep learning–assisted coral morphology cover across 742 sites on the Great Barrier Reef (2022–2025): A Great Reef Census citizen science dataset

Limnology and Oceanography Letters, Volume 11, Issue 6, November 2026.
Abstract Citizen science can expand the spatial extent of coral reef surveys, but its value is often limited by inconsistent data quality and slow manual analysis. Here we combine volunteer‐collected imagery with deep learning to overcome these constraints, delivering validated coral cover data at scale.

Integration of Aerosol–Cloud Interactions With a Land‐Atmosphere Coupled Model in the Gray Zone

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 11, November 2026.
Abstract Clouds strongly impact net surface radiation, creating differential heating patterns, and trigger land breezes that in turn organize cloud development. These dial processes determine the location of persistent ecohydrological regimes at local scales. Aerosol–cloud interactions (ACI) directly impact the diurnal cycle of cloud optical depth, and

Notch Filter-Based Active Damping Design Method of Three-phase Grid-Tied Voltage Source Inverter with Asymmetric-LCL Filter [PDF]

A high-order power filter is always used to filter out harmonics in grid-injected current. Compared with other power filters, the Asymmetric-LCL(A-LCL) filter has the advantages of having a small total inductance and strong robustness.
