WP5 – Multiple services provided by grid devices, large demand-response and RES generation coordinated in a smart management system

Key figures / Key points

  • Workforce: 468 person/months on 11 partners
  • Demo located in a relevant grid portion between Puglia and Basilicata Regions (7 different 150kV backbones, about 100 MW of RES plants, more than 50 MW of industrial loads)
  • Main expected result for the system: reduction of RES production curtailment (also through improvement of day-ahead forecasts for HV Lines Thermal Rating and RES production forecasts); assessment of reliability and potential of DSR for effective contribution to congestion management and other system services; assessment of reliability and potential of RES for effective contribution to system stability (inertia and AVC)


Why demonstrating services by wind farms and industrial loads?

Today most of the ancillary services are achieved by traditional power plants. Tomorrow, these plants will be less numerous and thus other providers of these flexibilities becomes necessary and could prove more cost-efficient.

Why innovative Dynamic Thermal Ratings?

DTR assess the real-time capacity of lines depending on weather conditions. To be accurate, it requires numerous sensors. Using advanced modelling features and cooperative computing could reduce the installation and maintenance costs.

Why an Energy Management System?

To ensure a cost effective congestion management, all flexibilities available should be considered. As more and more options are available (DTR, demand response…), the TSO operators need smart support to identify the best solution.

Modern electrical systems are undergoing radical transformations related to new scenarios of energy production, transmission and distribution that altogether determine a constantly increasing need for flexibilities in power systems.

Along with storage, the evolution of new technologies for the transmission system is focused, on one side, on the possibility for RES power plants (wind and PV especially) to contribute to frequency and voltage system control, and on the other side, to enable consumers and/or prosumers to effectively contribute to balancing capacity.

On the other hand, new methods for the coordination of Power Flow Control devices and in general the so-called “smart transmission grid technologies” can further increase the level of coordination in order to achieve an optimal coordination of flexibility services.

In this context, activities performed in WP5 envisage to demonstrate innovative advanced coordination schemes among multiple technologies for optimal congestion management and to enhance system stability based on demand-side response and RES generation flexibility services. This will be tested in a real-live environment and for a significant timeframe of 10 months.

The technologies that will be considered are, in particular:

  • Energy Management System for highly coordinated congestion management
  • Enhanced Line Dynamic Thermal Rating
  • Improved weather forecast algorithms and models for RES production and Dynamic Thermal Rating (DTR)
  • Enhanced Optimal Power Flow for EMS application
  • Innovative control scheme for RES synthetic inertia provision


The main goal of WP is to develop a smart management system integrating flexibility sources of market players together with flexibility sources of the TSO’s infrastructure. The demonstrator, in particular, will address the following use-cases:

  • Optimal Coordination for Congestion Management, implementing an advanced Energy Management System capable of handling large amount of data in order to coordinate Power Flow Control devices and Demand Side Response (DSR) resources for congestion management on a portion of the Italian transmission grid.
  • Innovative System Services from RES Plants, focusing on the provision of upward and downward Synthetic Inertia and Automatic Voltage Control by large wind/PV power plants. Innovative control algorithms will be implemented and tested with the purpose of assessing, on a real-environment framework, the reliability of this service, its effectiveness in increasing system stability with respect to power unbalances and the availability of RES power plants.
  • Increasing Availability of System services from DSR through Aggregation: also if DSR technologies represent a mature, commercially viable and potentially cheaper alternative to system services provided by conventional power plants, the availability of DSR resources on the European Ancillary Services Markets has not grown yet. This use case will address, through a deeper energy audit of involved customer’s productive process, the implementation and testing of Frequency Restoration Reserve and Automatic Voltage Control provided by consumers, with a focus on the role of HV aggregator as key player to increase DSR availability.
