Optimal Operation of A Micro Water-Energy Nexus
Open AccessWithin the emerging concepts of smart cities and smart buildings, several critical serviceslike electricity and water supply are supposed to be integrated by adopting and implementingthe cutting-edge technologies in control, communication and management/optimization.In such a smart environment, several physical systems could be connected and operatedjointly to achieve co-optimized decisions. Water as well as electricity are certainly twolifeline networks and essential resources in today’s daily life. From the perspective ofa power grid, water systems – including water distribution and treatment – consume asignificant amount of electricity power; so water systems can be considered as a criticalinfrastructure, the operation of which is dependent on and influencing the power gridoperation. Additionally, if judiciously integrated, some special loads in water systems, suchas irrigation, are controllable and could provide extra flexibility for the power grid operation.This thesis mainly focuses on the operation integration of both power and water systems.In the power system side, the alternation current (AC) power distribution systems integratedwith renewable energy resources and battery storage systems is introduced. In the watersystem side, the pipe network with its hydraulic characteristics is applied. The two systemsare connected and co-operated as one interdependent model, so called micro-nexus. Accordingly,a co-optimization framework is introduced and tested. Considering the individual andinterdependent characteristics of both power and water systems, the proposed model is amixed-integer non-linear programming formulation which runs in the GAMS optimizationenvironment and is tested on the modified IEEE 13-bus test system. The results show thepotential of co-operating the two systems for improving the flexibility and enhancing thesecurity of both systems.
