Robust Distributed Averaging Frequency Control of Inverter-Based Microgrids

Alireza Karimi, Christoph Manuel Kammer

We consider the problem of distributed primary and secondary frequency control in inverter-based microgrids with meshed topology. A dynamic phasor modeling approach is presented that accurately represents the dynamics of the grid while being suitably simpl ...

Control of the Actively Balanced Capacitive Voltage Divider for a Five-Level NPC Inverter - Estimation of the Intermediary Levels Currents

Alfred Rufer, Nicolas Cherix, Nelson William Koch

This article addresses the control of a Multistage Stacked Boost Architecture (MSBA) feeding a five-level NPC inverter in a grid-tied application. A suitable control strategy was previously presented, in which estimated/reconstructed intermediary currents ...

Critical light instability in CB/DIO processed PBDTTT-EFT:PC71BM organic photovoltaic devices

Konrad Domanski, Mojtaba Abdi Jalebi

Organic photovoltaic (OPV) devices often undergo 'burn-in' during the early stages of operation, this period describing the relatively rapid drop in power output before stabilising. For normal and inverted PBDTTT-EFT:PC71BM OPVs prepared according to curre ...

A Five-Level NPC Photovoltaic Inverter with an Actively Balanced Capacitive Voltage Divider

Alfred Rufer

A new five-level photovoltaic Inverter is presented, implemented by associating a Multistage Stacked Boost Architecture (MSBA) with a 5-level NPC inverter. Ahead of the MSBA conversion stage, a conventional boost converter allows the operation of the PV ce ...
