Abstract

Ergon Energy currently has an extensive Single Line Earth (SWER) network across vast areas of regional Queensland. Growing load has caused many of these networks to approach their capacity limit. This leads to voltage fluctuations and usually requires expensive augmentation works.
If a portion of the load on these networks was transferred from the peak load period to a period of low demand a more uniforming load curve would result. This would reduce the maximum demand of the line and negate the need for expensive augmentation works over long line lengths.
This project investigates pumped hydroelectric storage and SWER networks to gain a technical understanding of both technologies and their existing applications. It then analyses whether it is feasible to use pumped hydroelectric storage technology to negate the need for the line augmentation works described in the previous scenario. This feasibility is quantified by designing a pumped hydroelectric storage system and modelling its effect on an Ergon Energy SWER feeder.
The results show that it is technically possible to install a pumped hydroelectric storage scheme on a SWER feeder to improve voltage regulation augment its capacity. However, a detailed study should be undertaken before undertaking such a project as it is only feasible where the additional civil infrastructure required for the scheme is minimal.
