3 Smart Grid A smart grid is a modernized electrical grid that uses analogue [1] or digital information and communications technology to gather and act on information, such as information about the behaviours of suppliers and consumers, in an automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity.

10 Water Energy Nexus KISTERS AG 10 06/11/2014

11 Operations optimization and cost-control KISTERS AG 11 06/11/2014

12 What are the main concerns of Water Utilities? KISTERS AG 12 06/11/2014

13 Some figures Drinking water and wastewater systems account for approximately 3-4 percent of energy use in the United States Improving energy efficiency is an ongoing challenge for water sector utilities. While energy costs often represent 25-30% of a utility's total operation and maintenance (O&M) costs KISTERS AG USGS Presentation

17 Project: Optimisation Operations Water Utility Goal: Implement decision support system for the water supply system of the Commonwealth of Taibilla Channels (MCT) in South-East Spain. The MCT water supply system contains channels, pipes, storages, pump stations, desalination plants, and a water treatment plant. Triggers: Increasing energy costs Aging staff (specialists) Growing complexity of overall system, incl. inclusion of Renewable Energy Sources

18 Goals project CEO Quote: If you can secure the knowledge of my staff in your system, I ll be satisfied, if you can improve automation of my system on top, I ll be happy, if you on top of that save costs and increase profits... well... what shall I say... KISTERS AG USGS Presentation

19 Project: MCT (Spain): System Overview Water treatment plant Channels Desalination plant Pumping stations Storages Desalination plant Pressurized pipes Challenges: Capturing the entire complex system including delay time in the channels pressure in the pipes and storages

20 Project: MCT (Spain) benefits The major operational goal is cost optimal scheduling for the pumps, the storages and the water treatment plant. Improve the plan of the overall system Reduce the amount of water that is drained to avoid overflow in channels Reduce the energy consumption for pumping stations Reduce the energy costs The optimization system can also be applied to support the medium-term planning as well as the development of the infrastructure.

21 Power prices for OMEL market The OMEL power spot market from is represented by this price curve A simple calcaluation: => (n_pumps * power_used) + (m_desalination * power_used) => Sum_power_used * OMEL price_average KISTERS AYESA Workshop 21 06/11/2014 => power_costs / year

24 ResOpt Topology Partial Water System EBAP = Estaciones de Bombeo de Agua Potable (Drinking Water Pumping Stations

25 Overview results ResOpt: Constraints pump Pump status over time Defining maximum startups: - For a fixed period of time - Whole period chosen for optimization

26 Overview results ResOpt Results: Operation scheduling for pumps and turbine. KISTERS Partner Week /11/2014

27 Energy Supply Contracts Energy prices and variation depend on consumption and the penalties. Can be defined as time series. (HFC= Hourly Forecast Curve)

28 Operational and strategic outcomes Deepening and formalization of hydraulic system knowledge quantification, extraction of staff know-how Improved pump scheduling and storage management varying water demand, operational constraints, costs of water from different sources, varying prices in power markets Organisation better prepared for future smart water grid challenges and dynamics Renewables, make-or-buy decision, planning KISTERS AG USGS Presentation
