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