Virtual Storage is an innovative solution that allows the integration of different electrochemical storage systems within a single coordinated network. This approach provides essential support to critical services for the management of the electricity grid, such as peak shaving (reduction of peaks in demand) and load levelling (balance the load). The ability to coordinate and aggregate these distributed storage systems is essential to optimize operational efficiency and ensure the stability of the electricity system, especially in scenarios characterized by unexpected events, such as sudden changes in energy demand or generation capacity.
To successfully implement a Virtual Storage system, it is essential to equip the individual storage systems with interface devices, both hardware and software, designed to allow aggregated and coordinated management of the Storage Systems (SdA) distributed along the network.
In this context, the ViStoFaRe proposal fits in, whose main objective is to develop and implement an advanced conversion device, called StorInPlus, accompanied by specific control strategies for the interfacing of electrochemical SdAs to the network. The latter are typically coupled to generators powered by Non-Programmable Renewable Sources, such as solar or wind plants, characterized by an intrinsically variable production. In parallel, the project envisages the creation of a digital platform, called ViSto, dedicated to the interfacing with the network operator and to the coordination of a variable number (n) of SdAs, collectively managed as a single Virtual Storage.
The main strength of the ViStoFaRe proposal lies in the design and implementation of the StorInPlus device, which operates in a Virtual Storage perspective through the ViSto platform; the solution aims to respond effectively to the needs of users and producers, integrating the peculiarities of non-programmable renewable sources in a more resilient and adaptable system.
