Abstract
Integrated local multi-energy systems are recognized as a promising bottom-up alternative to achieve the ambitious energy and climate goals set by the European Commission (EC) for 2030. The nature of integrated multi-energy systems presumes a very complex interaction of different aspects from various energy sectors, which historically worked almost independently. Therefore, configuration and development of an integrated local energy system under the energy community concept is an extremely demanding task, requiring a sound interdisciplinary knowledge base. In this sense, it becomes critically important to have a thorough understanding of the technologies that make use of locally available resources and thus enable evolution and deployment of energy communities across Europe.
