Development of a hybrid energy storage system

According to Spain’s Energy Storage Strategy, to achieve the objectives set out in the Integrated National Energy and Climate Plan (NECP) and the Long-Term Decarbonisation Strategy, it is necessary to increase energy storage capacity from 8.3 GW in 2021 to around 20 GW by 2030. This represents a significant increase in the amount of storage to be installed in order to achieve the established renewable integration objectives.  

In addition to the peninsular territory, the island systems (Balearic and Canary Islands) represent locations of special interest for the installation of energy storage, since in them the levels of penetration of renewable energies in the electricity mix are more limited as a result of their isolated nature or less interconnection of their electricity systems. 

Based on these needs, this “VisynC” project aims at the development and validation on a real scale of a hybrid storage system that combines lithium-ion batteries and ultracapacitors whose management is carried out through a specific control system that allows it to operate in synchronous grid-forming mode.  

The new storage system will be connected to the high-voltage transmission grid in the Lanzarote-Fuerteventura electricity system, specifically in the 66 kV Mácher substation, and will operate as an integrated grid asset, providing a wide variety of services to guarantee the safe operation of the electricity system and the increase of the integration of renewable energies. 

The connection to the transmission grid will be made through a GIS mobile shielded cell isolated as an alternative solution to SF6 gas, which will allow progress in the knowledge and experience of solutions that allow the substitution of this gas with a high GWP, global warming potential index. 

The proposed system would have a capacity of 16 MW (18.8 MVA of maximum apparent power) and 3.45 MWh of energy storage capacity.
