Fast and Practical Method for Model Reduction of Large-Scale Water-Distribution Networks
Publication: Journal of Water Resources Planning and Management
Volume 140, Issue 4
Abstract
This paper presents a method for the reduction of network models described by a system of nonlinear algebraic equations. Such models are, for example, present when modeling water networks, electrical networks, and gas networks. The approach calculates a network model equivalent to the original one, but containing fewer components. This procedure has an advantage compared with straightforward linearization because the reduced nonlinear model preserves the nonlinearity of the original model and approximates the original model in a wide range of operating conditions. The method is applicable to hydraulic analysis and has been validated by simplifying many practical water network models for optimization studies.
