General Impedance Modeling for Modular Multilevel Converter with Grid-forming and Grid-following Control

arXiv.org
Modular multilevel converter (MMC) has complex topology, control architecture and broadband harmonic spectrum. For this, linear-time-periodic (LTP) theory, covering multi-harmonic coupling relations, has been adopted for MMC impedance modeling recently ...

PLL-less Active and Reactive Power Controller for Grid-Following Inverter

2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020
This paper presents a control scheme for single-phase grid-following inverters that does not rely on the phase-locked-loop (PLL) algorithm for synchronizing the injected current with the grid. The absence of the PLL avoids unstable low damping modes that are possibly originated from the PLL’s nonlinear nature.

Fault Ride-through for Cascaded Inverters Using Mixed Grid-forming and Grid-following Control

European Conference on Cognitive Ergonomics
Series-connected dc-ac converters commonly appear in medium-voltage grid-connected applications. In this paper, we seek a decentralized control approach that enables series-connected converters to ride through nonideal grid conditions.

Hybrid Control Scheme for VSC Presenting Both Grid-Forming and Grid-Following Capabilities

IEEE Transactions on Power Delivery, 2022
This work proposes the Hybrid Control Converter (HCC), a new kind of VSC control. This method aims to have one single converter mimic the behavior of two individual, virtual converters working in parallel (one with grid-following and the other with grid ...

Multisampled current control of grid-following voltage source converters

Pulse width modulation (PWM)–based current control is widely used in grid-following voltage source converters (VSCs). However, a large control delay is induced in the regular PWM process, which limits the current control bandwidth and deteriorates VSC-grid interactive stability.
