Urban energy systems with smart multi-carrier energy networks and renewable energy generation

摘要: Abstract Employing different energy carrier networks in connection with distributed renewable generation is an attractive way to improve sustainability urban areas. An effective option increase local production convert surplus electricity into e.g. thermal energy. Here a methodology study such multi-carrier systems presented which enables analyze spatial demand and supply, flows. The results indicate that northern midsized city wind power coupled both electric grid district heating network could raise the allowable capacity over non-heat case by 40–200%. In Asian megacity dominated cooling demand, employing dispatched photovoltaics tri-generation cover even beyond 30% of all lead major carbon emission reductions.
