Real-time operation of water infrastructure is an important element in managing water systems. What do we mean by ‘managing water systems’? This includes, but is not limited to, the operation of river and reservoir systems for flood control, irrigation and hydropower production, and operation of urban drainage systems for storm and wastewater management.
Traditionally, real-time operation of such systems is carried out using rule-based control of individual controllable elements. There is a significant potential for enhancing the operational efficiency of water systems by global, system-wide optimisation of all control structures.
Developing real-time control solutions to tackle water problems
In an on-going R&D project, a new technology is being developed that solves large system-wide optimisation and control problems in real-time. The technology is based on a Model Predictive Control (MPC) framework that uses a dynamic model of the system to optimise the operations. The framework ensures transparent and cost-efficient solutions for implementation in real-time forecasting and operation systems. The generic basis of the MPC technology allows us to efficiently develop real-time control solutions for a wide range of different types of water problems.
The technology has been demonstrated with a prototype real-time forecasting and operations system of the Murrumbidgee River in New South Wales, Australia. With the new system, the irrigation scheduling in the Murrumbidgee River is optimised in order to support three major irrigation areas as well as over 700 individual users along the 1300 km river. In addition, the optimisation ensures that other operational goals in terms of environmental flow requirements and minimisation of losses of water are met.
