System HILP Event Demand Disconnection (SHEDD) Project

-New LFDD Schemes  

An Online Technical Webinar

Wednesday 22nd September 2021 | 12.30 to 13:30


The SHEDD project investigates alternative Low Frequency Demand Disconnect (LFDD) design options with the aim of evaluating the potential technical, economic, and social performance improvement through implementation of these alternative LFDD options within short (≤ 5 years) and medium-long (> 5 years) terms.

The project has reviewed the Great Britain (GB) LFDD schemes and investigated the potential benefits of introducing a new design to the LFDD scheme which can better protect the network from sudden severe deviations in the system frequency, whilst minimising the impact to network customers.

The project has provided recommendations and specifications of new alternative LFDD solutions which can improve the performance of the LFDD schemes in the future as electricity networks continue to transition towards Net Zero.
