Optimal Stochastic Water-Energy Nexus Management for Cooperative Prosumers in Modern Multi-Energy Networks

Nowadays, significant developments of hybrid energy systems have been led to their widespread presence in the energy network's interactions and have made the interdependent analysis of energy networks essential. In this regard, the inextricable role of the water in the production process of various forms of energy has created a great need for innovative water-energy nexus models in modernizing future multi-vector energy grids. To this end, this paper proposes an innovative water-energy nexus model for optimal energy management of prosumers in the modern energy infrastructure. In the proposed model, each prosumer benefits from wind and PV units for generating clean power, storage units for ensuring continuous power and water supply, hydrogen technology for energy conversion, as well as the water well and water desalination units for serving water demand. Due to the essentiality of uncertainty modeling for gaining confident results in the system engaged with a 100% level of renewables, the stochastic assessment is conducted by generating scenarios using an autoregressive integrated moving average approach as well as reducing the number of scenarios by applying fast forward reduction method. The applicability of the proposed model is examined in the IEEE 6-bus power distribution system. The results highlighted the effectiveness of the offered model in optimally managing the energy of prosumers in the water-energy nexus system.
