摘要
为了充分消纳清洁能源、提高能源利用效率,综合能源系统的概念应运而生,相较于传统的能源单级利用形式,综合能源系统对电力、冷热和天然气等多种形式能源进行多级利用,通过多能互补提高综合能源利用效率。但是综合能源系统由于系统间耦合紧密,能源流动变化复杂,在优化运行方面相较于传统电网有较大差别。针对综合能源系统优化运行问题的研究现状进行了全面整理,首先介绍了综合能源系统的组成,对电力、热力和天然气的网络潮流模型的研究现状进行了归纳分析;其次对优化运行方法进行了分类总结,分析了现有方法的优缺点和难点;最后进行了展望,指明了综合能源系统优化运行未来的研究方向。
In order to fully consume clean energy and improve energy efficiency,the concept of integrated energy system was put foward.Compared with the traditional single-stage energy utilization,integrated energy system makes multi-level use of various forms of energy such as power,heat and cold and natural gas,and achieves the improvement of integrated energy utilization efficiency through multi-energy complementarity.However,due to the close coupling between the systems and the complex changes of energy flow,the integrated energy system is quite different from the traditional power grid in terms of optimal operation.The research status of optimal operation of integrated energy system was comprehensively sorted out.Firstly,the composition of integrated energy system was introduced.The research status of power,heat and natural gas network power flow models was summarized and analyzed.Secondly,the optimal operation methods were classified and summarized,and the advantages,disadvantages and difficulties of existing methods were analyzed.Finally,the future research direction of the integrated energy system was pointed out.
