Objectives This project looks to install measuring equipment panels within selected substations to allow the continuous recording of power quality and sampling of the inertia (rotating mass which ensures power frequency stability) of the Western Isles (WI) network when running in island mode. It is anticipated that by carrying out these measurements the following can be obtained:• Power quality of the supply on the WI in island mode.• Amount of system inertia under different network conditions during an extended period.This data will be used to validate existing models and determine if additional renewable generation can still be accommodated in island mode, thus reducing costs to customers from prolonged diesel operation. The outputs from the project will also help inform the development of long-term solutions to replace the existing fleet of fixed diesels with lower carbon alternatives. Monitoring technology to be deployed at key locations to allow the continuous recording of power quality and sampling of the inertia of the Western Isles (WI) network when running in island mode.Data from the monitored system will be examined to measure power quality and establish the inertia of the system at the instant of the disturbance by -• Installing additional Phasor based monitoring units at selected Primary substations to monitor power quality.• Installing a load bank and electronic switch to create constant micro disturbance to the system, enabling continuous inertia measurement.The findings from this project will be used directly to assess the effectiveness or the current Distribution system operating procedures during island mode. These findings will also be used in future studies aimed at reducing future reliance on diesel generation and the transition to net zero. The objectives of the project are –• To gather detailed network data when in island mode.• Determine if the power quality on the Western Isles whilst in island mode has the potential to facilitate additional embedded renewable generation volumes.• Validate the following operating models whilst in island mode:- SHEPD diesel generator parameters (Battery Point & Arnish).- Distributed Generator parameters.- Contribution of Western Isles load to inertia.• Complete studies to confirm the amount of Distributed Generation export which can be allowed.
Abstract This project aims to install measurement technology namely in the Western Isles to monitor power quality and inertia during extended network outages known as island mode. Data gathered from the project will be used to validate the existing network operating models used during island mode. In island mode, distributed generation (DG) is curtailed to 10% of network load with diesel generation supplying the bulk of electricity and network inertia. The learning from the project will inform future studies which may allow an increase in DG, which in turn will reduce the reliance on diesel generation reducing overall costs and carbon emissions. In increase in distributed generation will also increase the revenue to generators during extended outages, many of which are community operated.
