The prototypes developed within (IEGSA platform) focusing mostly on establishing a pan-EU clearing market will be deployed in two demonstrations. The first demonstration is situated in Bulgaria and Romania deploying a wholesale and retail market integration platform with advanced AI-based demand and RES generation forecasting tool, which introduces incentives for market participation to DERs and prosumers and flexibility services providers. The demonstration will include scenarios of market coupling with Greek market as well. The second demonstration will be situated in the Romanian market, providing an alternative solution of “spatial aggregation of technological flexibility” to solve grid related constraints regarding flexibility sources on DSO level and propagate local DER flexibility into the wholesale market.
