In this webinar, we will focus on one of them - aFRR, automatic Frequency Restoration Reserve. We will discuss technological requirements connected with delivering this product as well as regulation in the European Union, especially in the context of PICASSO project (Platform for the International Coordination of Automated Frequency Restoration and Stable System Operation).

Additionally, we will shortly describe the differences between aFRR and other two balancing service products primary (FCR) and tertiary (mFRR) control power. Furthermore, we will show examples of successful integration of distributed renewables delivering ancillary services using technology of a Virtual Power Plant. Taking example of Germany, we will present a theoretical revenue calculation that will illustrate the potential of the aFRR product in central-western Europe.
