Operation optimisation of water distribution system

This PhD project aims to improve current water distribution operations. By designing a generic framework to optimise pumping operations, the goal is to help operators better manage water demands and reduce energy expenses.

About this project

Water distribution systems (WDSs) are crucial for delivering water from sources to homes, businesses, farms, and other users.

In Brisbane and Sydney, for example, the energy used for water distribution is higher than the global average, putting pressure on the sector to cut energy use and costs.

One way to reduce energy consumption is by coordinating the operation of water pumps, especially during peak electricity price periods. However, this optimisation is challenging due to unpredictable water demands, varying pressure requirements, and fluctuating electricity prices. Additionally, advances in pump technology and the integration of renewable energy sources make the system more complex and harder to manage.

This research project aims to develop a generic framework to optimise water delivery operations.

Goals include:

1. comparing different optimisation methods to help choose the best ones for future water distribution system operation
2. improving water distribution system operations by considering real-life uncertainties like fluctuating water demands and electricity prices; and
3. solving the problems of slow or impossible calculations when optimising large, complex water delivery systems with many storage facilities and pump stations.

Outcomes

This project aims to create a generic set of rules that determine the best times to turn pumps on and off, considering all the complexities, to minimize energy costs effectively.
