Optimal operation of the energy network (electricity - gas) considering solar, wind, and energy storages system based on energy hub modeling
Abstract
In this paper, the Energy Hub (EH) is considered as a super-node connecting the different forms of energy including electricity, natural gas, solar energy, and wind energy; then through conversion equipment and energy storage systems to meet the demand for electricity, heat, and cooling of small loads. GAMS is used to solve the optimal operation problem of Energy Network (EN) with the objective of minimizing the cost of energy and greenhouse emission (NO 2 , SO 2 , and CO 2 ). The effect of distributed energy, energy storage systems on the performance of EN is assessed through four different operating scenarios. Compared to traditional electricity supply, results showed that EN dramatically changed the characteristics of electricity consumption line chart and natural gas purchased from the system; thus, increasing efficiency and optimal use of energy compared to the conventional architecture of using a single energy source.
