Editorial: Energy hubs in modern energy systems with renewables and energy storage

An energy hub is a multi-generator system in which many energy carriers are converted, stored, and supplied for several energy types to meet energy consumption challenges. In these systems, the energy conversion matrix changes over time due to the external impact of the surrounding environment (sun, weather, water, fuel, etc.), transmission line operating conditions, and operators’ objectives. Thus, different energy infrastructures are used in terms of production, transmission, and distribution of energy, while the entire transmission is realized with the definition of clear benefits in terms of quality and economy of energy transmission. Therefore, as visualized in Figure 1, one of the big challenges in the efficient and economical operation of energy hub systems is the optimal management of both production and energy storage and transmission systems. This necessitates a practical distributed energy management framework for modeling and optimizing the functioning of these systems using powerful optimization algorithms to decide the duration, coordination, communication, and operation prediction of all individual elements.
