Optimal supply of energy resources has become a major challenge around the world. Traditionally, operation of the gas and electricity system infrastructures has been separated. With the growth of using natural gas-powered electric power generation systems and the change in attitudes toward various energy systems to reduce costs, the integration of electricity and natural gas systems has become more important than ever. In addition, economic aspects and coordination between different forms of energy to improve supply efficiency in energy systems are important factors that affect the operation of energy systems.
The idea of multi-carrier energy systems and energy hubs has been proposed as an effective method to reduce energy costs, increase energy efficiency and energy supply reliability. In this regard, energy hubs have been introduced as an efficient concept with the ability to trade, convert and store different types of energy to supply power on the demand side, which allows different energy networks to have their desired effect on each other's performance for the system to improve generally. These energy hubs can have different types of energy at their input and output, which can vary depending on the under-study energy hub.
In this thesis, the model of an energy hub in terms of operation and long-term operation planning of different energy sources such as electrical and thermal is presented. In this regard, the main purpose of this study is to present and improve the mathematical models of an energy hub, which includes various equipment such as FC and CHP generation units, electrical and thermal storage equipment, electric vehicles and hydrogen tanks. Electric and thermal demand response programs are also regarded to increase network flexibility and reduce operating costs. In addition, this modeling includes both the electricity and heat markets, and is simulated in a stochastic environment, which is based on risk and scenario.
Finally, the simulation results show that the operating cost of the considered energy hub compared to the energy hubs without equipment and technologies such as the FC unit and the demand response program is reduced.
