Grid Forming Inverters: New Technologies for Voltage & Frequency Stabilisation

Synopsis

About 40% of total installed power of energy sources in polish energy system are renewables today. This ratio is going to increase rapidly next years. The result of such state is that traditional, fossil-fuel-based sources, which offered stability services are not enough anymore. There is a need that renewable sources will take out part of this functionality. As RES are definitely not stable and controllable because of relation to weather conditions, they require additional equipment to participate in that task.

• This session will describe new types of “grid forming” inverters coupled with energy storages, which can support the grid or even be the main source there, and shape voltage & frequency directly.
• Innovative technology used here allows to make energy system less related with traditional power plants and is real milestone towards the decarbonization.
• The session will also include examples of applications and other factors of energy system stability.
