Abstract

The transition to a net-zero energy system requires a massive change in the way that electricity is produced, transported, and used; the power electronic converters are the core of this paradigm-shifting, and the control techniques used on them have a primary influence in the power system dynamic behavior. The most recent advances in more flexible commutation devices and sophisticated control mechanisms, together with appropriate practices and grid codes, are making the voltage source converter (VSC) interfaced technologies a precious component of the operation of modern and future power systems and paving the way to a secure transition to a zero-carbon society. The so-called grid forming control technique applied to the VSC of inverter-based resources emerged as a promising element to accelerate the growth to the net zero energy system. However, there are plenty of positions regarding the definitions of grid forming control and their types. The talk starts by presenting the main features of the synchronous machine and the services that the machine can naturally offer; then, the power electronic converter is introduced, showing the main features. Then, the functionality and services of grid forming are presented, and the most representative control techniques presented in the literature are presented. The talk shows some of the implementations of grid-forming control techniques using offline simulation (DIgSILENT PowerFactory) and then accurate time simulation (OPAL-RT and Typhoon HIL). The talk finishes by presenting the current specification of grid forming control shown in the grid code of Great Britain and the proposed aspects in Australia.
