Improving energy efficiency in water distribution systems based on water consumption profiling
Environmental Engineering and Management Journal › Vol. 7 › Nr. 3 AbstractTogether with other public utilities, water supply systems management aims to provide an efficient operation of the system and lower operational costs. In complex water distribution systems there is a large variety of consumers, which differ from one another not only by values of inflows, but also by how this inflows vary from hour to hour. This paper presents a self-organizing based approach to the problem of classification of water consumption profiles from the nodes of a water distrib...
