Fair Energy Sharing in Local Communities: Dynamic Participation of Prosumers

A method optimizing dynamic participation of prosumers in local energy communities is proposed. First, an optimization model maximizing the social welfare is applied to a community including PV systems and battery storages. The PV generation is peer-to-peer traded within the community considering each prosumer’s individual willingness-to-pay for local PV generation. Dynamic participation is studied by adding a new prosumer and varying installed PV capacity and willingness-topay. The proposed method finds a new optimum of the extended community considering constraints limiting the deviation of each prosumer’s annual profits and GHG emissions after adding the new prosumer compared to the original community.
