Abstract
The latest international environmental sustainability agreements set very strict targets for the building stock de-carbonisation and the exploitation of renewable sources. These targets can be achieved by reducing the users interaction with the electrical grid. Future networks will rely more and more on distributed energy generation and increased interaction between the prosumers. This paper presents a model to assess the technical, environmental and economical benefits of peer-to-peer (P2P) electricity sharing compared to traditional peer-to-grid (P2G) schemes. The P2P scheme is implemented in a small local energy community where the PV production surplus of a user can be consumed by another and the storage capacity is shared between the houses, ultimately improving the overall independence from the grid
