Sincro.Grid is a smart grids investment project of common EU interest under development in Slovenia and Croatia. One of the main goals of the project is to create conditions that provide for efficient integration of distributed renewable power generation sources in the transmission and distribution systems of Croatia and Slovenia.
As part of the project, battery energy storage systems with a total capacity of 10 MW will be installed in various locations across Slovenia. This is enough to meet about 15% of the domestic demand for the forms of flexibility with the fastest response times.
Storage systems will use battery cells with a lifetime of up to 20 years, similar to those that are already used in computers and smart phones. Rather than a research prototype, this is a mature, commercially available technology.
The main challenge of implementing grid-scale energy storage is not its technological development or physical installation, it is the management of data and algorithms that optimise the charging and discharging processes.
The volume of energy stored in the system at a given point in time and the charging/discharging rate matter. This affects the efficiency and life of the system.
Another challenge is what other services the energy storage system can offer, both to energy consumers and to enhance the stability of the grid.
Benefits to consumers
The main benefits include the security and quality of power supply.
The results of the Sincro.Grid project obtained by means of grid-scale energy storage tests and storage operation data management tests will have a positive impact on the future development of small-scale storage systems used by consumers.
