Abstract

In today's world, energy conservation is a major concern. The overuse of conventional energy resources led to their rapid depletion, and consequently caused environmental issues like global climate change because of the release of carbon dioxide and other toxic substances into the atmosphere. This led to an increase in the research of using clean renewable resources and methods of utilizing energy in an efficient manner. Similarly, another vital resource which is necessary for survival is potable water. Hence, there is an important need to optimize both energy and water resources. Traditionally water distribution and power transmission networks are thought of as separate uncoupled infrastructure systems. However, in reality, they are very much coupled. Exploring the coupling between power and water, commonly known as the energy water nexus offers a very interesting opportunity. There are many examples of this coupling like water usage in the energy supply chain, energy usage in water supply chain, water and energy used together in homes and industries and so on. Another level of coupling is introduced by co-production desalination facilities that use the thermal energy, produced as a byproduct of power production. These deliver more than just power, they are used to produce dual products like power and heat or power and water. The fuel is used much more efficiently in these plants, and they provide the added advantage of providing additional useful products, like heating for houses in the northern European countries or providing desalinated drinking water in the Middle Eastern countries. In light of these facts, this thesis focuses on how to simultaneously optimize the dispatch and transmission of three types of generating plants i.e power production plants, co-production plants and water production plants . In particular, an optimization program is provided that minimizes total costs as a function of power and water generation subject to production and transmission constraints. The program provides a systematic method of achieving optimal results and can serve as basis for set-points upon which individual plants can implement their optimal control. In so doing, it contributes to the ongoing grand-challenge of improving the sustainability of the energy-water nexus.
