“…To minimize the total operational cost and to serve the extra wind power systems, using MI-SOCP, the authors in [25] develop a model that integrates electrical, heating, and water systems. Likewise, a model that optimally schedules water tanks and pumps was developed in [26] to collect renewable energy from the electrical grid.…”

“…A method that modifies the electric grid economic dispatch is proposed in [28] to include a water system by focusing mainly on the cogeneration of electricity and water from fossil fuel plants; however, this work ignores the network structure and other cooperation aspects. The models proposed in [25][26][27] investigate the potential demand response of the water network as an electric demand, yet the water production is not linked to the electrical system.…”

As water and electrical networks cannot be entirely independent, a more integrated approach, the water–energy nexus (WEN), is developed. A WEN is the basis of a smart city where water and electrical networks are interconnected and integrated by implementing efficient management strategies. Accordingly, this study develops a dynamic co-optimization model for designing and operating an integrated power and water system. The proposed co-optimization model minimizes the total annual and operational costs of a micro-WEN system while capturing its optimum design values and operating conditions and meeting the demands of the electrical and water networks. Furthermore, this work presents a plan for transitioning from thermal desalination to reverse osmosis (RO) desalination in the United Arab Emirates (UAE). The key objective is to decouple electricity and water production, effectively tackling the issue of operating the UAE’s power plants at low efficiency during the winter while ensuring an adequate water supply to meet the growing demand. The results show that the co-optimization model provides a significant reduction in the total operational cost with the integration of photovoltaic energy and shifting to RO. Most importantly, the micro-WEN system is optimized over multiple timescales to reduce the computation effort and memory requirements.
