Abstract

Optimal pumping scheduling model for energy cost minimization: two different resolution methods J. Sousa\ M. da Conceigao Cunha* & A. Sa Marques^ ' Department of Civil Engineering, Polytechnic Institute ofCoimbra, Portugal * Department of Civil Engineering, Coimbra University, Portugal Abstract A large pipeline system is usually one of the components of a water distribution system. This will carry water from the sources to the distribution reservoirs, often by means of costly pumping stations, since local topography may include areas of high ground. The pumping timetable should be designed to accommodate the fluctuation of energy costs over a twenty-four - hour period, with preference being given to pumping during off-peak hours. This solution may not always be possible, however, because of operating constraints it could be necessary pumping during peak energy-cost periods, and so the optimal solution will have to recommend the most effective period for pumping, bearing in
