Resilience oriented water and energy hub scheduling considering maintenance constraint

In this paper resilience oriented water and energy hub scheduling for a remote area is presented. The optimal operation scheduling considering maintenance programming and reliability indices are presented. Demands which include electricity, heat and drinking waters are supplied by diesel generators, boilers, combined heat and power units, and drinking water sources such as desalination units and transferring water. The considered system contains renewable energy resources such as wind turbine and photovoltaic arrays as well as electrical storage units. In order to enhance resiliency of system against forced outages of components and regular maintenance programs, maintenance constraints and reliability of supply have been addressed. The proposed formulation aims at taking the best use of the beneficial degrees of freedom associated with these units for decreasing total costs and increasing reliability subject to maintenance constraints and feasible operating region of components. The effectiveness of the proposed method is validated by implementation on a real remote region using mixed integer linear programming. The mathematical problem is solved in GAMS optimization package using CPLEX solver. •Optimal operation and maintenance scheduling for energy and water hub is studied.•The problem is modeled as mixed integer linear programming.•Resilient perspective in energy water hub against maintenance is defined.•The reliability concept energy and drinking water demands are addressed.•The reverse osmosis desalination unit is developed in water supply procedure.
