Optimal operation and scheduling of residential energy hubs simultaneously considering optimal sizing of heat storage and battery storage systems

Popis výsledku v původním jazyce

The energy systems, including heat and electrical load demands, particularly residential energy systems, could be effectively managed by applying the multi-carrier energy hub concepts. Although various research works have presented different methods for optimal operation and optimal planning of residential energy hubs (REHs), the optimal interconnected operation and sizing of the energy storage system (ESS) have received less attention. This paper attempts to respond to the discussed research gap by developing a new optimization problem based on simultaneous optimal operation and optimal capacity of ESS in REHs. The comparative analysis of the heat storage system (HSS), battery storage system (BSS), and hybrid ESS consists of both HSS and BSS is one of the essential contributions of this study. Test results illustrate the advantages of applying the proposed method compared to the optimal daily cost of REH equipped with a non-optimum capacity of ESS. The positive impacts of the optimized hybrid ESS, including HSS and BSS, are more than HSS and BSS significantly. Test results show that the daily cost of REH consists of operation cost, and the daily cost of ESS for the optimal hybrid ESS is 1.99% and 5.87% better than using the HSS and BSS, respectively. Performing further sensitivity analysis under various scenarios based on electricity and gas pricing is another advantage of this research. Furthermore, the impacts of the policies corresponding to the price of electricity sold and electricity purchased on the optimal sizing of the ESS and the operation cost of the REHs are studied.
