With the growth of renewables, the increased interconnection of European grids, the development of local energy initiatives, and the specific requirements on TSO – DSO cooperation as set forth in the different Network Codes and Guidelines, TSOs and DSOs face new challenges that will require greater coordination. The European Commission adopted legislative proposals on the energy market that promote cooperation among network operators as they procure balancing, congestion management and ancillary services. The measures encourage procurement of services at both the transmission and distribution level, recognizing that this will enable more efficient and effective network management, will increase the level of demand response and the capacity of renewable generation. TSOs and DSOs must now define the services they want to procure in collaboration with market participants, and must set up ways to procure them in a coordinated manner. Digitalisation is a key driver for coordination and active system management in the electricity grid, enabling TSOs and DSOs to optimise the use of distributed resources and ensure a cost-effective and secure supply of electricity but also empowers end-users to become active market participants, supporting self-generation and providing demand flexibility. To support the transformation, the INTERRFACE project will design, develop and exploit an Interoperable pan-European Grid Services Architecture to act as the interface between the power system (TSO and DSO) and the customers and allow the seamless and coordinated operation of all stakeholders to use and procure common services. State-of-the-art digital tools based on blockchains and big data management will provide new opportunities for electricity market participation and thus engage consumers into the INTERRFACE proposed market structures that will be designed to exploit Distributed Energy Resources.

By 2020, several areas of the HVAC pan-European transmission system will be operated with extremely high penetrations of Power Electronics(PE)-interfaced generators, thus becoming the only generating units for some periods of the day or of the year – due to renewable (wind, solar) electricity. This will result in i) growing dynamic stability issues for the power system (possibly a new major barrier against future renewable penetration), ii) the necessity to upgrade existing protection schemes and iii) measures to mitigate the resulting degradation of power quality due to harmonics propagation. European TSOs from Estonia, Finland, France, Germany, Iceland, Ireland, Italy, Netherlands, Slovenia, Spain and UK have joined to address such challenges with manufacturers (Alstom, Enercon, Schneider Electric) and universities/research centres. They propose innovative solutions to progressively adjust the HVAC system operations. Firstly, a replicable methodology is developed for appraising the distance of any EU 28 control zone to instability due to PE proliferation and for monitoring it in real time, along with a portfolio of incremental improvements of existing technologies (the tuning of controllers, a pilot test of wide-area control techniques and the upgrading of protection devices with impacts on the present grid codes). Next, innovative power system control laws are designed to cope with the lack of synchronous machines. Numerical simulations and laboratory tests deliver promising control solutions together with recommendations for new PE grid connection rules and the development of a novel protection technology and mitigation of the foreseen power quality disturbances. Technology and economic impacts of such innovations are quantified together with barriers to be overcome in order to recommend future deployment scenarios. Dissemination activities support the deployment schemes of the project outputs based on knowledge sharing among targeted stakeholders at EC level.

While the electrical grid is moving from being a fully centralized to a highly decentralized system, grid operators have to change their operative business to accommodate for faster reactions and adaptive exploitation of flexibility. The topic has been subject of several research projects in the past years and reached a maturity that allows now the consideration of a final level, proposing an integrated view on the grid operations beyond the traditional barriers. OneNet aims at performing this critical step creating the conditions for a new generation of grid services able to fully exploit demand response, storage and distributed generation while creating fair, transparent and open conditions for the consumer. As result, while creating one network of Europe, the project aims to build a customer centric approach to grid operation. This ambitious view is achieved by proposing new markets, products and services and by creating a unique IT architecture. While a single platform for Europe is not thinkable, OneNet proposes innovative mechanisms of platform federation which are the key technical enablers for the proposed vision. The project has also very ambitious exploitation goals aiming at creating consensus on the solution far beyond the limits of the consortium partners thanks to a variety of actions including a large-scale forum for discussion within the international energy community. The complete concept is also proven in 4 cluster demos creating an involvement of an unprecedented number of countries and their grid operators in a single project. The consortium, in addition to a significant list of grid operators, includes also key IT players, leading research institutions and the two most relevant associations for grid operators, jointly providing a unique set of expertise in support to these challenging tasks.
