The energy hub is an umbrella concept that can cover all energy technologies and systems. So various energy systems with different sizes can be modeled with this concept. However, in terms of size, energy hubs can be classified into two classes of micro energy

Energy system

Energy systems can range in scope, from local, municipal, national, and regional, to global, depending on issues under investigation. Researchers may or may not include demand side measures within their definition of an energy system. The Intergovernmental Panel on Climate Change (IPCC) does so, for instance, but covers these measures in separate chapters on
