Description: The inherent, intermittent and stochastic nature of renewable energy sources (RES) has raised the interest of system operators and market agents on finding effective solutions to improve controllability, flexibility and reliability of power systems. From a market point of view, innovative exploitation models should be proposed to mitigate the effects of the variability and unpredictability of renewable energies in terms of dynamic prices and flexible trade among the participants in that market. Furthermore, operational technical solutions should be integrated in current power networks to ensure continuous and efficient flow of energy, as well as operational compatibility of multiple areas and networks, avoiding congestion and malfunctioning of the power system.
Within this demonstration specific focus will be given to implement and adapt an intelligent controller (Intelligent Distribution Node), to be connected at the point of supply of a group of buildings and demonstrate a common set of grid services for DSOs and TSOs but also aiding Balancing Responsible Party (BRP). This demonstration involves all necessary lab preparations as well as the actual realization, operation and analysis of results of the field demonstration. The work in this task mainly involves the demonstrator deployment, commissioning and systems integration, the players integration, in order to familiarize TSO, DSO, aggregators and end users with the resources and functionalities provided by the IDN and with the interfaces to be used to access to its management platforms (GRMS and ERMS) and well as to its information hub and finally the demonstrator operation, monitoring and analysis.
 
 
Objective and ambition
Combination of local congestion management markets with wholesale and balancing markets
Ancillary services provision by aggregated end-users, prosumers and distributed generation
Usage of digital information and communication technologies, like wide-area measurement systems, computational intelligence, big-data analytics, and networked control in modern power systems operation
Management of small-scale assets at the distribution level addressed to improve TSO and DSO interconnection in procuring energy services
Predictive grid models of the subsidiary network under the IDN to be used by TSOs and DSOs to improve system operation
Foundations for new network codes, particularly on demand-response aggregated under IDNs
New mechanism for end-user aggregators to provide grid services and increase the share of renewables
