The core of this project proposal is based on the dimensioning of renewable energy systems and hybrid energy storage systems for not only individual optimisations, but also in function of neighboring consumers and the parent network: how can the energy infrastructure for residential, commercial and industrial customers? in addition to individual benefits, also generate additional benefits such as flexibility, security of supply and shared profit at the local level? The broad target group includes every low-voltage or medium-voltage (10kv) distribution system user who is aiming for or already owns decentralized energy production. Specifically, the focus is mainly on industrial SMEs - with a maximum connection capacity of 5 MW - and privately operated building complexes for resp. flexibility and shared profit solutions. The stakeholders of the project, on the other hand, are installers and innovative players in the energy sector who are eager to participate in the renewable wave and want to take their future market position in this. The results of this research will also provide added value for collective initiatives for the integration of large PV installations or medium-sized wind turbines (>500 kW) on the local distribution network
