The LIINES is happy to announce that the Energy Journal has accepted our recent paper entitled: The Impact of Storage Facility Capacity and Ramping Capabilities on the Supply Side of the Energy-Water Nexus. The paper is authored by Apoorva Santhosh, Prof. Amro M. Farid and Prof. Kamal Youcef-Toumi. It builds upon an earlier publication entitled: Real-Time Economic Dispatch for the Supply Side of the Energy-Water Nexus which was summarized in an earlier blog post.
As previous blog posts have discussed, the topic of the energy-water nexus is timely. In the Gulf Cooperation Council nations, it is of particular relevance because of the hot and arid climate. Water scarcity is further aggravated high energy demands for cooling. The GCC nations, however, have a tremendous opportunity in that they often operate their power and water infrastructure under a single operational entity. Furthermore, the presence of cogeneration facilities such as Multi-Stage Flash desalination facilities fundamentally couple the power and water grids.
This paper expands upon the previously published economic dispatch problem to now include the impact of ramping rates and storage capacities. The latter is shown to alleviate binding production constraints and flatten production levels to achieve lower costs. Three cases studies are presented; a base case, a second case inspired by Singapore’s limited water storage availability, and a third case relevant to countries in the Middle East where water storage facilities can be readily constructed. Storage facilities are shown to reduce total operating costs by up to 38% and lead to less variable daily production suggesting that they have an important role to play in the optimization of the energy-water nexus.
