[Group 03] Smart Water / Smart Power
Light at the end of the tunnel!
Week four has been the most challenging week so far, but we are no less passionate. Our optimisation program is finally complete with an extra pump and tank. Our focus this week was mainly on the report and we are making good progress. A special mention to the proofreading team Ryan, Divya, Julian and Clinton who have been working very hard on making sure our report is of the highest academic standard. Finally, we have even started producing a prize winning poster summarising our findings. All in all Group 3 are doing better than ever.
It's been a week of all work and no play for the team at H2.0. A strenuous week has seen the group working in the design office for full days with little breaks in order to meet the clients expectations, to no avail. It seems as if the team has been on the wrong track for a while now, and the comments of a dissatisfied client has led us to turn around some of the structure and focus of our project in order to improve for the following week.
In other news, the team has begun formulating recommendations for the Feasibility Study and Steve has successfully optimised the reservoir network with his beautifully iterating linear optimisation programme. Our achievements are plentiful, and we hope that the client can appreciate this in the weeks to come.
After the preliminary work in the first week, the team at H2.0 has continued to work in the three individual subteams, developing upon the feedback given by our supervisor and client, in order to focus our findings in more detail.
The beginning of the week was heavily focussed on the Development Presentations which demonstrated the project and the team’s initial findings to the other teams and a panel of judges consisting of supervisors, other academics and industry professionals. The presentation can be found here:
The remainder of the week was focused on using feedback from the presentation to develop the project’s findings into a more defined scope. The energy and markets team continued researching and developing an understanding bout how energy demand and supply functions in the United Kingdom and the factors that affect this. The optimisation team has worked in more detail on defining the optimisation problem by identifying constraints and formulating an initial objective function. The hydraulic modelling team continues to work with the EPANET software to develop a network structure which is solvable and realistic along with working together with the optimisation team to address the hydraulic feasibility of the pump schedule.

The team at H2.0 have begun researching into developing a techno-economic feasibility study for optimising the operation of water supply systems so that they can be used as an energy storage component of future energy systems. The water supply industry makes up about 3% of the United Kingdom’s energy consumer, and up to 90% of that consumption can be attributed to pumping of water. Therefore, reducing energy use by optimising pumping is the focal point of the “Smart Water / Smart Power” project.
Energy demand and water demand vary throughout the day, and so do their costs. The day can broadly be split into peak and off-peak periods, with the peak prices being higher. It would then make sense to confine energy usage and water pumping to less-expensive off-peak times. However, electricity is very difficult to store in large quantities. Therefore, using electricity and pumping in a less-expensive off-peak time when demand is low is relatively pointless if there is no storage. These are the factors which are to e taken into consideration when formulating our pump scheduling optimisation model. Additionally, the national grid works as a market and there are regulatory issues involved when working with both the energy system and the water supply system.
In order to efficiently and productively address the problem, the H2.0 project team has divided into three subteams: Pumped Storage, Markets and Regulations and Hydraulics. The Pumped Storage subteam has been looking into an optimisation scheme for the pump scheduling system for water utilities. The Markets and Regulations subteam have been looking into energy demand and the legislative regulations to which utility companies must abide. The Hydraulics subteam has been investigating the effects of pumping on a pipe network and its characteristics in order to develop a hydraulic model.
