An Improved Grid Voltage Feedforward Compensation Scheme of Grid-Connected Inverter in Weak Grid

2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018
The grid voltage feedforward control strategy is widely used in the grid-connected inverter, aiming to reduce the disturbance of grid voltage distortion and suppress the impulse current of inverter at startup. However, an extra positive feedback channel will be introduced into the current control loop in weak grid, bringing low harmonics and even ...

STATCOM control for integration of wind farm to the weak grid

2014 IEEE PES General Meeting | Conference & Exposition, 2014
This paper focuses on the STATCOM modeling and nonlinear controller design for fast voltage regulation during the grid disturbance when the wind farm is integrated to a weak grid. A sliding mode inverse controller for the STATCOM connected at the PCC of the wind farm is proposed.

Stability analysis for weak grids with power electronics interfaces

IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016
A novel modelling method and a stability analysis procedure for weak power networks with high penetration of power electronics converters are proposed in this paper. The modeling approach can be applied to any network topology and in order to model of the complete network it introduces small-signal state-space models for each network component ...

Hybrid power plant control in weak grids: grid following vs. grid forming

IET Conference Proceedings
This paper studies the performance of grid-following and grid-forming controllers utilized as asset level control in Hybrid Power Plants (HPPs) while connecting to weak grid. In this regard, the overall configuration of HPP consisting of wind, solar and battery energy storage system has been simulated in time domain, using PSCAD software.

Grid-Forming Converters in Weak Grids – The Case of a Mediterranean Island

2019
The existing power network of a Mediterranean island is used as test bed for the study of grid-forming converter dynamics in weak grid conditions. The control scheme adopted for the converter falls in the category of the so called virtual synchronous machines (VSM). Particular attention is committed to the interaction between the converter controls and
