Editorial: Grid Connection of Converters in Renewable Applications [PDF]
Frontiers in Energy Research, 2021 Energy generated from renewable sources is fed into the grid by means of electronic power converters. These can be supervised at system (grid) level to coordinate all productions points together with storages and loads. Regulations impose power supply quality requirements regarding harmonics, grid fault response and low voltage ride through (LVRT). The

A Universal Controller for Grid-Connected Voltage-Source Converters [PDF]
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2021 Power-synchronization control (PSC) and vector current control (VCC), the latter including cascaded outer loops, are, respectively, considered to be grid-forming and grid-following schemes. They have significant structural differences. Despite that, it is here shown that the two schemes can be unified by making a series of minor modifications to PSC ...

Stability of interacting grid-connected power converters [PDF]
Journal of Modern Power Systems and Clean Energy, 2013 The power grid in a typical micro distribution system is non-ideal, presenting itself as a voltage source with significant impedance. Thus, grid-connected converters interact with each other via the non-ideal grid. In this study, we consider the practical scenario of voltage-source converters connected to a three-phase voltage source with significant ...

Distributed control of a fault tolerant modular multilevel inverter for direct-drive wind turbine grid interfacing [PDF]
, 2013 Modular generator and converter topologies are being pursued for large offshore wind turbines to achieve fault tolerance and high reliability. A centralized controller presents a single critical point of failure which has prevented a truly modular and ...

Modelling and Simulation of Power Systems with Grid-Connected Converters in OpenModelica
2022 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2022 This paper analyses the capabilities of the OpenModelica environment to perform electromagnetic transient (EMT) type simulations of power transmission systems with grid-connected converters. A power transmission system has been modelled and simulated in OpenModelica and Simulink to compare both tools in terms of accuracy, robustness, flexibility and ...

Data-Enabled Predictive Control for Grid-Connected Power Converters [PDF]
2019 IEEE 58th Conference on Decision and Control (CDC), 2019 We apply a novel data-enabled predictive control (DeePC) algorithm in grid-connected power converters to perform safe and optimal control. Rather than a model, the DeePC algorithm solely needs input/output data measured from the unknown system to predict future trajectories.

Design for passivity in the Z-domain for LCL grid-connected converters [PDF]
IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016 This paper develops a design methodology aimed to shape passive the admittance of the LCL grid-connected voltage source converters (VSCs). A novel aspect of this work is the assessment of the range of frequencies for control design: due to discrete and PWM operation, the effectiveness of the control action is more and more reduced as frequency ...
