HYBRID OPTIMISATION ALGORITHMS FOR CONTROL OF WATER DISTRIBUTION SYSTEMS

This paper presents an approach to integrated control of quantity and quality in water distribution systems. The integrated control meets consumer demand for drinking-quality water and maintains constraints while minimizing the operating costs. The predictive control uses 24 hours demand prediction and mathematical model of the water distribution system to operate it. The structure of basic control consists of two layers. The approach to optimising control at the upper layer, using mixed integer linear and genetic algorithm solver and, at last, the combination of them – hybrid solver, is presented in this paper.
