Grid Forming Converter Technology and Applications

2022
One of the drawbacks of the increasing use of (mostly inverter fed) renewable technologies is the reduction in transient stability of power systems with high renewable penetration. Grid forming inverters provide one solution to maintaining power system stability.

Systematic Design of a DLQR Applied to Grid-Forming Converters

IEEE Journal of Emerging and Selected Topics in Industrial Electronics, 2020
This paper proposes a systematic state-space procedure to design an optimal discrete-time linear quadratic regulator applied to grid-forming converters. A comprehensive mathematical modeling of a voltage-sourced converter with an LC output filter is performed and a systematic way of including digital resonant compensators is addressed.

Synchronous Converter Role in a Grid Forming System

IET Conference Proceedings, 2021
There is a greater acceptance of the connection of an increasing share of renewable energy sources to electrical power networks at either grid or local utilization voltage levels as the electrical power network operators contend with the competing challenges of changing and increasing load demands, and continuing pressures to reduce net carbon ...

Multifunctional Grid-Forming Converter Control Based on a Disturbance Observer

IEEE Transactions on Power Electronics
A multifunctional grid-forming control method based on a disturbance observer structure is proposed for grid converters. The proposed method has several different control modes, including the grid-forming, grid-following, and current control modes.

Stability of grid forming converters under electromechanical restrictions

IET Conference Proceedings
In this paper, the large signal stability of a grid-forming wind power generation system is analyzed. The conventional methodology of power curves is applied to the grid-forming inverter, incorporating the effects of virtual impedance and current limitations.

Stability of power networks with grid-forming converters

2019 IEEE Milan PowerTech, 2019
Due to an increase in converter-interfaced renewable generation, power networks are becoming increasingly reliant on power converters, which have contrasting dynamical behaviour to rotating machines with large inertia. This results in new control challenges for the power grid.
