丹麦区域能源互联网发展综述

A Review of Development of Integrated District Energy System in Denmark

区域能源互联网作为加速促进世界向可持续能源转变的重要手段之一,在近期倍受关注。丹麦是世界上较早使用以区域供暖为主的区域能源手段来解决能源问题的国家,目前正在积极推动向具有综合能源特性和以灵活性交易为互联手段的区域能源互联网的转型。文章对丹麦区域能源互联网的发展历史和现状作了简要介绍;对相关的理念和示范经验给出了具体描述;指出了当前区域能源互联网在技术上所遇到的瓶颈。文章将会为中国的区域能源互联网发展提供国际上的经验与参考。

As one o f the major solutions to accelerate the transition towards a sustainable energy society, integrated district energy system has recently attracted worldwide attention. Denmark has a long history of using district heating-based energy technologies to address its energy issues. Upgrade its present district energy technology towards an integrated district energy system （IDES） solution is currently under intensive investigation. The desired IDES is an integrated energy solution across multiple energy sectors, and use market-based flexibility trading to optimally facilitate the cross-sector cooperation. Besides clarifying some key concepts, this paper presents a review of various Danish research and demonstration activities related to developing IDES and identifies a number of technical challenges. The knowledge and experience learned from Denmark will serve the development of IDES in China as a good reference.
