摘要
本文针对综合能源系统电热联合潮流计算问题,首先基于电热双向耦合建立了含有2个热电联产机组(CHP)耦合节点的电热双向耦合潮流模型;然后分析了电锅炉的耦合状态和系统负荷变化对系统潮流的影响;最后基于牛顿拉夫逊顺序求解算法,选取某一区域综合能源系统进行算例分析,利用MATLAB软件求解出电热混合潮流。结果表明:电热双向耦合网络通过耦合节点CHP1、CHP2交互作用,相互影响达到潮流平衡,验证了所给模型的有效性;电热耦合潮流随着电锅炉耦合状态和系统负荷变化而变化,显示出多能流系统源-网-荷互动特性。通过对电热耦合网络的潮流研究,可以为电热耦合综合能源系统的规划运行提供指导,并且为进一步多能流耦合潮流研究提供思路。
Against the power flow calculation problem of combined electric and thermal for integrated energy system,firstly,a two-way coupled power flow model with two combined heat and power(CHP)unit coupling nodes is established based on the two-way coupling.Then,the influence of coupling state of the electric boiler and the change of the system load on the system power flow is analyzed.Finally,a regional integrated energy system is selected for case analysis,and MATLAB is used to solve the combined power flow based on the Newton Raphson sequence algorithm.The results show that,the coupling nodes CHP1 and CHP2 interact with each other to achieve power flow balance,which verifies the validity of the model.The power flow of combined electric and thermal changes with the coupling state of electric boiler and the system load,which shows the source network load interaction characteristics of multi energy flow system.Research on power flow of the combined electric and thermal network can provides guidance for planning and operation of the electric heat coupling comprehensive energy system,and provides ideas for further research on the multi energy flow coupling power flow.
