National Grid plugs TagEnergy’s 100MW battery project in at its Drax substation. Following energisation, the facility in North Yorkshire is the UK’s largest transmission connected battery energy storage system (BESS). The facility is supporting Britain’s clean energy transition, and helping to ensure secure operation of the electricity system.
The projects include a consortium led by LiNa Energy that will develop a new sodium nickel chloride battery system, leading to improved cell performance, and manufacturing optimised for scale-up, decarbonisation and recycling. Another, led by Anaphite Ltd, aims to develop faster charging batteries by incorporating graphene into the battery cathode.
A battery storage project developed by TagEnergy is now connected and energised on the electricity transmission network, following work by National Grid to plug the facility into its 132kV Drax substation in North Yorkshire.
Owned and operated by TagEnergy – with Tesla, Habitat Energy and RES as project partners – the newly-connected battery will help exploit the clean electricity potential of renewable projects in the region, storing and releasing green energy to power homes and businesses and also helping to relieve any system constraints.
To achieve battery state estimation in complex scenarios such as a wide temperature range and a wide aging range, the BIT team proposed a multi aging stage model-driven battery SOH and SOC fusion estimation method .
Under the premise that there is no major breakthrough in Li-ion battery technology and performance is not significantly improved, the key to improving the service life of the battery pack is to ensure the consistency between battery cells as much as possible. (2) σ = ∑ V i − V 2 n, V a = σ / V
