Summary
Optimal operational planning of multi‐energy systems is a major concern regarding the technoeconomic and environmental objectives. Considering the requirements for energy storage in energy hubs, different energy storage models have been studied in the literature. However, proposing a comprehensive multi‐storage model is a necessity in this context. In the present research, a multiobjective optimization model has been developed to determine the optimal operational scenario in an energy hub. The novel dynamic energy storage hub (DESH) concept with interconnected short‐ and long‐term electricity storage facilities is well defined. Also, the synergy advantageous due to the connection of thermal and electrical storage units through the DESH scheme is proposed. Moreover, technoeconomic merits of storing surplus power in hybrid energy systems using ammonia as the energy carrier in presence of renewable energy sources (RES) are investigated. In this regard, the effects of different meteorological conditions and also various time horizons have been examined for a commercial consumer. The current results show the applicability of the proposed model for increasing the energy hub performance considering defined assessment tools. Compared with the base case, results for a 3‐day operating plan of the DESH in April reveal that exergy destruction and operational costs for the best operating scenario are decreased by 24.36% and 21.63%, respectively. Also, the energy hub produces 3.5 tons of ammonia utilizing the available surplus power of the conventional power plant and RES. Furthermore, it is demonstrated that adding environmental penalty costs in the optimization model increases the operational costs by 21% and decreases the available surplus power of in‐service gas turbogenerators for storage up to 54% in the best operating scenario.
