For the replacement of fossil fuel forestry biomass should help mitigating Green House Gas (GHG) emissions. However the supply of energy wood is challenging because of high supply costs and rapidly increasing demand. Considering the typical, heterogeneous structure of landownership, contractors and energy producers in Mid-Europe, supply network optimization becomes of major importance. Mathemat...
Modern gas-fired power stations are discussed as an alternative for replacing eventually decommissioned nuclear power stations. With an also increasing number of smallest-scale gas turbines, the importance of the gas network is hence likely to increase in coming years. The presence of converters as e.g. a combined cycle gas turbine raises the question if and to what extent the electrical networ...
