Elewit, the technology platform of Spanish grid operator REE, said it plans to build one of the world’s first systems that it claims will function as a virtual synchronous compensator. The company’s Hesstec unit is building the factory in Lanzarote, Canary Islands.
“This will be the largest system of this type, at least in Europe, and will provide stability to the entire Lanzarote-Fuerteventura system,” a Hesstec spokesperson said. pv magazine.
The system is part of the ViSync project, which aims to develop and validate a fully hybrid storage system combining lithium-ion batteries and ultracapacitors. It will use a specific operating system to operate in synchronous rasterization mode.
Synchronous grid formation, a control type for power electronics converters, allows storage systems with power electronics to set the grid frequency reference and provide services similar to synchronous generators. These services, which are not feasible with current generators, require high power and fast response.
The new storage system will be connected to the high-voltage transmission network in the Lanzarote-Fuerteventura electrical system, in particular to the 66 kV substation of Mácher. It will serve as an integrated network asset and provide various services to ensure the safe operation of the electrical system and improve the integration of renewable energy.
Hesstec plans to install a hybrid storage system, offering the 18.8 MVA power stage with grid-forming capacity and a hybrid solution based on ultracapacitors, with capacities of 16 MW and 80 MW.
“ViSync is a disruptive project born from Red Eléctrica’s collaboration with Hesstec, CEN Solutions, S2 Grupo and CERE, and opens the way to a new way to regulate and operate networks in a more dynamic way, allowing stability is added and greater penetration of renewable energies,” Hesstec said.
ViSync is also a beneficiary project of PERTE ERHA, a strategic state program aimed at the recovery and economic transformation of renewable energy, renewable hydrogen and storage.
Elewit was founded in 2019 to provide solutions to the new challenges of the electricity and telecom sectors. The company claims that “Hesstec is one of the company’s top bets.”
