WP5 – Multiple services provided by grid devices, large demand-response and RES generation coordinated in a smart management system
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.
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.
WP status (November 2020)
The demonstration is located in a HV grid portion in Apulia and Basilicata (South Italy), featuring a high occurrence of congestions and the presence of wind power plants and industrial loads. Seven industrial loads will participate for a total of ~ 121 MW of theoretical regulating capacity: the required upgrades are about to be completed in their respective premises. The same goes for the two wind parks involved and their storage facilities. On transmission side, sensors for Dynamic Thermal Rating were installed on seven 150kV lines, and some first measurements were acquired from the DTR sensor nodes. Complementarily, the master node was installed at TERNA substation. At software level, the zonal Energy Management system has been developed and first instances executed. TERNA’s system was adapted for the Z-EMS installation, and cybersecurity analysis conducted. The demonstrator will be in operation by the end of 2020.
