Currently, apart from High (HV) and Medium Voltage (MV) levels, the Smart Grid infrastructure in mainland Portugal is comprised of more than 2 million smart meters ready to interface home energy management systems, and over 15 thousand smart secondary substations.
Portuguese DEMO will set, test and assess the potentiality of the innovative approach to the standard and optimized interconnectivity between grid operators and the different electricity market players.
This will be done in four DEMO-sites which include residential ecosystem with several technologies, industrial consumers in locations with substantial penetration of decentralized generation, agriculture irrigation systems, EDP’s Electric Vehicle (EV) fleet charging stations, and MV and LV networks equipped with storage assets.
Besides connecting to two market platforms, E-REDES smart grid will also interact with third-party solutions for the provision of flexibility services from the agriculture sector, residential and industrial, customers and the EV charging operator.
The Portuguese DEMO-sites complement each other not only in the scope of the tools and services to be tested, such as smart grid functionalities, congestion management, resiliency, demand side response, flexibility mapping, amongst others, but also by providing an effective mean to demonstrate the universality of the UMEI concept.
 Demonstrate the feasibility of market coordinated mechanisms and the UMEI to integrate flexibility services
 Enable an integrated system architecture to maximize the aggregated benefit of stakeholders in Portuguese market
 Combine new Distribution Energy Resources (DER) with existing assets, including customer’s flexibility
 Demonstrate the combined operation of DERs (e.g., industrial and residential loads) and advanced grid automation
 Improve the observability of MV networks
 Demonstrate market mechanisms through UMEI to: validate transactions in local energy markets, solve distribution system unbalances and inefficiencies (grid congestion, voltage deviations, etc.) and test the interconnectivity between DSO and third parties’ platforms
 Balance, validate and arbitrate in an adequate time horizon different market offers from different market players, enabling the market participation of complementary players
 Integrate market platforms for addressing flexibilities
 Foster new business models via a marketplace for flexibility trading (i.e., DSO as a flexibility enabler, “user” and facilitator)
