Optimal operation efficiency and control of water pumps in multiple water reservoir system: case study in Korea

Abstract

Pumping regimes for water distribution systems have been established to reduce pump operation costs. Optimization of water reservoir networks has been studied extensively for operating pumps efficiently. According to research, optimization reduces pump operation costs by approximately 10–20%. However, comparing economic benefits per country would be too complex because the effects of optimization differ depending on the power cost estimation system of each country and the existing operations. This study presents an optimization algorithm to minimize the operating costs of an entire system via the application of dynamic programming. Case studies were conducted to apply the algorithm to real values in four scenarios. By setting cost minimization as an objective, an optimum water pump operation plan was derived that encompasses operating conditions, variations in water demand, and energy costs. Results showed that operating a standby pump in an existing system can increase the system's efficiency. In addition, even if hourly water consumption remains constant, each case requires its own operating method, because each case has different operational costs. By considering various conditions such as those mentioned in this study, future pump operation schedules can be optimized and stabilized to maintain economic water supply.

Lost in optimisation of water distribution systems? A literature review of system operation

“…EPANET) may prevent implementation for large WDSs in real-time, due to considerable computational effort required (Giacomello et al 2013). For this reason, more efficient deterministic methods have been increasingly applied (Arai et al 2013;Bagirov et al 2008;Bagirov et al 2013;Bagirov et al 2012;Bene et al 2013;Gleixner et al 2012;Goryashko and Nemirovski 2014;Kim et al 2015;Kim et al 2007;Price and Ostfeld 2013a;Price and Ostfeld 2013b;Price and Ostfeld 2014;Reca et al 2014;Ulanicki et al 2007).…”
