多能协同综合能源系统示范工程现状与展望

Status and prospect of pilot projects of integrated energy system with multi-energy collaboration

综合能源系统集成了供电、供热和供气等系统,充分发掘了各个能源系统的潜力,成为当今能源系统发展的主要方向。总结了国内外综合能源系统示范工程的现状,分析了国内外示范工程的实践经验。国外的成功案例表明,政策支持是发展综合能源系统的基础,多能协调控制是实现能源协同互补的关键技术,有利于能源的高效利用与可再生能源的大规模消纳。进一步通过国内外示范工程在政策及技术等方面的对比,结合我国目前的能源现状,给出了我国发展综合能源系统的建议。

Being the main direction of energy system development,the integrated energy system consisting of power supply,heating supply,gas supply,and so on fully exploits the potentials of different energy systems. The status of its pilot projects,domestic and abroad,is summarized and their practical experiences are analyzed. The successful cases of abroad projects show that,the policy support is the basis of its development and the multi-energy coordinated control is the key technology of multi-energy complementation for the efficient utilization of energy and the large-scale accommodation of renewable energy. Comparison between domestic and abroad pilot projects is further carried out in the aspects of policy and technology. Combined with the present situation of China＇s energy,suggestions about the domestic development of integrated energy system are given.
