D3.5 Description and report of energy exchange and smart trading tool including simulation studies for living labs as active LECs. Preliminary version

GSY, in collaboration with project partners, has enhanced the Grid Singularity Exchange software (Energy exchange and smart trading tool for LEC with coupled networks) by developing, integrating and testing digital twins of the heat pump and district heating (virtual heat pump and heat demand digital twin). The solution was then demonstrated at SONNE by simulating multiple scenaria and deploying the developed digital twins as part of the enhanced GSY Simulation Tool (also termed Singularity Map) to evaluate the role of district heating in local energy markets, the impact of flexibility assets and otherwise assess sector coupling and peer-to-peer benefits for individuals organised in energy communities. This report presents the related development, the testing and the demonstration study results.
