Pump schedules optimisation with pressure aspects in complex large-scale water distribution systems

Abstract: Abstract. This paper considers optimisation of pump and valve schedules in complex large-scale water distribution networks (WDN), taking into account pressure aspects such as minimum service pressure and pressuredependent leakage. An optimisation model is automatically generated in the GAMS language from a hydraulic model in the EPANET format and from additional files describing operational constraints, electricity tariffs and pump station configurations. The paper describes in details how each hydraulic compo… Show more

“…The implementation of valve control actions depends on valve construction. We refer interested readers to [15,36,31,1,37] for more details. The deployment of PRVs in water distribution networks can promote the potential control availability.…”

“…Note that the head loss H i,j [k] is a non-negative variable. For more information on valves, we refer the reader to [27]- [28]. 6) Pipes: When a pipe (i, j) ∈ L carries a non-zero water flow, energy must be conserved between the two junctions i and j; otherwise, the pressure heads at junctions i and j are decoupled.…”

“…Recent demonstrations of PRVs have shown their benefits in control capabilities [27]- [28], and have incentivized water network operators to invest in PRVs. In the near future, we envision PRVs will be available at all junctions with multiple incoming-outgoing pipes.…”

“…Control of network elements such as valves and pumps, for optimal pressure, leakage and pipe damage reduction and energy cost minimization has been the focus of numerous works in the literature (for example Wright et al (2015); León-Celi et al (2018); Fooladivanda & Taylor (2018); Skworcow et al (2014); Ghaddar et al (2015Ghaddar et al ( , 2017). Furthermore, the use of variable speed pumps (instead of fixed speed) offers greater control and adaptability within a water distribution network, which can increase energy savings and reduce maintenance costs (Page et al, 2017).…”
