Integrated energy system is of great importance to improve energy efficiency and achieve sustainable development of energy. Multi-energy flow calculation is an important basic work for the planning,operation and control of integrated energy system. In order to make the related field workers carry out the research work of integrated energy system better, this paper reviews multi-energy flow calculation of integrated energy system. From two aspects of model and method,current research has been sorted out. First of all,the problem of multi-energy flow calculation is introduced. Then, the classification and generalization of multi-energy flow calculation models in electricity-gas-heat combined system are carried out. On this basis, the methods for solving the models are summarized. At last, some problems existing in multi-energy flow calculation of integrated energy system are put forward and some suggestions are given.%综合能源系统对提高能源利用率、实现能源可持续发展具有重要意义.多能流潮流计算是综合能源系统规划、运行、控制的重要基础工作.为了使相关领域工作者更好地开展综合能源系统方面的研究工作,该文以综合能源系统的多能流潮流计算为对象开展综述,从计算模型和求解方法2个角度,对当前的研究工作和进展进行梳理.首先,对多能流潮流计算问题进行介绍;然后,对电-气-热综合能源系统的多能流潮流计算模型进行分类和总结,在此基础上,对模型的求解方法进行概括和总结;最后,提出当前综合能源系统多能流潮流计算方面存在的问题,并给出一些建议.
