Strathclyde University spin-out Smarter Grid Solutions has successfully completed the second phase of a project aiming to demonstrate the benefits of fast-acting hybrid batteries connected to electricity networks.
The project, which is funded by the Korea Battery Industry Association (KBIA), demonstrates the benefits of using hybrid energy storage systems to enhance the capacity of electricity grids and microgrids when electricity demand is low and generation is high.
The project is supported by the University of Strathclyde’s Power Networks Demonstration Centre (PNDC), in Cumbernauld, Greater Glasgow.
Batteries “an important addition”
The system is controlled by Smarter Grid Solutions’ Active Network Management (ANM) software products (ANM Strata and ANM Element) which are simultaneously controlling the battery and its connection to the grid whilst running a simulation of a 950kw wind-turbine using data from the company’s Orkney ANM System.
Graham Ault, Executive Vice President of Smarter Grid Solutions said, “This project shows how energy storage systems can be used as an effective extra layer in the energy mix in the UK and how batteries will be an important addition in the transition to a smarter, more flexible system”
Phase 3 will see the connection of a 1MWh hybrid battery to the grid. The hybrid battery benefits from using a lithium-ion portion of the battery making it immediately available in the support of quickly changing grid conditions. A secondary zinc-bromine portion of the battery charges and discharges at a slower rate thus making this hybrid battery more valuable over longer periods of time. The ANM system installed at the TUV Nel test site at East Kilbride will manage both the battery and wind turbines connections to the grid.
When the project is completed the system and hardware will be deployed to a community project in Scotland the details of which are yet to be confirmed by the project team.
