Today, due to the increasing need for different energies, the request for communication between the sources of producing energy carriers has also expanded. Also, according to global policies to reduce greenhouse gas emissions, the tendency to use renewable energy sources, especially wind and solar energy is increasing appreciably. But to create a system with high reliability, the uncertainty of wind speed and solar radiation must are taken into account in order to obtain more realistic results. Therefore, an integrated energy system with several energy carriers is introduced as an effective way to integrate and use different flexible energy sources such as electricity, natural gas, heat and water, which is able to improve the total efficiency of energy consumption and reduce the challenges of operating multiple energy supplies. One of the simultaneous planning solutions of multi-carrier energy system with high efficiency and flexibility is the energy hub concept. In an energy hub, energy carrier’s inputs face the demands that are the outputs of the energy hub after it is generated, transformed, stored, or directly consumed. It is also possible to manage the energy carriers by demand response programs on the demand side. In this study, to simultaneous planning of multi energy carrier, an 18-bus test network is designed with three energy hubs tailored to electricity, heating, cooling, gas, water and hydrogen energy demands in the summer and winter seasons. This model is proposed as a mixed integer linear programing constrained multi-objective optimization problem. It minimizes the total cost and emission simultaneously. In addition to supplying electricity, energy hubs are also connected directly to supply heating and cooling energy. The results show that in addition to satisfying the constraints and the balance between production and energy demand, the costs and emissions are reduced in case studies with renewable energy sources, storage devices, equipment, energy management programs, and especially the connection of energy hubs for heating and cooling energy supply.
