摘要

It is a great pleasure to welcome you to the first International Conference on SmartEnergy Systems and 4th Generation District Heating at Aalborg University, CopenhagenCampus on 25-26 August 2015. The conference is organised by the 4DH StrategicResearch Centre in collaboration with Aalborg University and offers more than 70presentations in 3 parallel sessions with more than 180 participants from 25 countriesaround the world. The aim is to present and discuss scientific findings and industrialexperiences related to the development of Smart Energy Systems and future 4thGeneration District Heating Technologies and Systems (4GDH). This development isfundamental to the implementation of the European 2020 goals as well as futuresustainable energy solutions in general.The Smart Energy System approach was defined in 2011 in the CEESA project. The projectaddressed Danish scenarios with a particular focus on renewable energy in the transportsystem in a context with limited access to bioenergy.The Smart Energy System concept is essential for 100% renewable energy systems toharvest storage synergies and exploit low-value heat sources. As opposed to, for instance,the smart grid concept, which takes a sole focus on the electricity sector, the smartenergy systems approach includes the entire energy system in its identification of suitableenergy infrastructure designs and operation strategies. Focusing solely on the smartelectricity grid often leads to the definition of transmission lines, flexible electricitydemands, and electricity storage as the primary means to dealing with the integration offluctuating renewable sources. However, these measures are neither very effective norcost-efficient considering the nature of wind power and similar sources. The mosteffective and least-cost solutions are to be found when the electricity sector is combinedwith the heating and cooling sectors and/or the transport sector. Moreover, thecombination of electricity and gas infrastructures may play an important role in thedesign of future renewable energy systems.In its research on low-temperature district heating, the Strategic Research Centre for 4thGeneration District Heating Technologies and Systems enhances the understanding ofsupply system design, infrastructure and heat savings. In future energy systems,combinations of low-temperature district heating resources and heat savings represent apromising alternative to individual heating solutions and passive or energy+ buildings.This change in the heating system also requires institutional and organisational changesthat address the implementation of new technologies and enable new markets that canprovide feasible solutions to society.We hope you all will have a fruitful conference.Prof. Henrik Lund and Prof. Brian Vad MathiesenConference organisers
