Abstract

This paper presents operation of an energy hub (EH) to meet gas, thermal and electrical load. The EH is integrated with combined heat and power system, boiler unit, heat storage system, wind turbine, electric vehicles (EV s) and power- to-gas (P2G) storage system. In order to enhance the flexibility of EH, load shifting type demand response (DR) program is also included. The EH operation problem is modeled as mixed integer linear programming problem and solved to optimize total operation cost using CPLEX solver. Further, effect of three different charging models of EV s, (i) uncontrolled charging, (ii) only charging and (iii) vehicle-to-grid on operation of EH is also investigated in this work. Different case studies are framed and compared to investigate the effect of integrating EVs, P2G and DR technologies on operation of EH. Simulation results verify the efficacy of proposed model in optimally coordinating interaction between multinle technologies of EH.
