Swarm grids are an emerging approach to electrification in the Global South that interconnects individual household generation and storage to a small electricity network to make full use of existing generation capacities. Using a simulation tool for demand, weather, and power flows, we analyse the potential of an AC swarm grid for a large pre-electrified village in rural Yemen. Service quality and
The heating sector accounts for a major part of Germanys energy consumption and carbon emissions. Both, renewable energy and power-to-heat, could help decarbonizing it. To analyse the impacts of power-to-heat and heat storage on power system development, a dynamic long-term power sector investment and dispatch model for Europe is extended to also include German individual and district heating.
