| dc.description.abstract | The operational pressure control is a cost-e®ective way to leakage reduction and many pressure control methods and algorithms have been developed. Whilst the pres- sure control algorithm is model-based, the hydraulic model of the considered distribu- tion network is not always available. Therefore, this paper will focus on the development of an aggregated hydraulic model of the network considered, in particular, identi¯ca- tion of a leakage enhanced model using the operational measurements or the available historical data. This will enable a pressure optimisation algorithm to calculate the optimal pressure schedules for the implementation of a pressure control scheme. The identi¯cation problem is formulated as a parameter estimation problem in this paper and a least-square based method is derived for estimating the parameters in the model. A case study provided by a UK water company is performed to illustrate the use of the method and the identi¯cation results from real operational data are presented. | en |
