Abstract

This study develops a real-time near-optimal pump scheduling model for water transmission networks. The model aims to minimize energy cost by means of optimal pump operation while meeting system demands and satisfying operational constraints. The real-time control is realized using Supervisory Control and Data Acquisition (SCADA) system, by which system monitoring data is collected and the optimal control decisions are sent to the pumping stations for implementation. The model is composed of three simulation modules, such as demand forecasting, hydraulic simulation, and optimization. Decision variables include pump on/off (binary code of 0/1) schedules for fixed-rate pumps for each time-step over pre-defined operation time horizon. Various operational constraints are embedded in the model reflecting real operational practices. The proposed optimization model is demonstrated using a real, medium-sized water transmission system in Seoul, South Korea and showed 19~27% energy cost savings compared to a conventional operation scheme.
