中文摘要:
      由于区域综合能源系统中存在电、热等难以耦合分析的多种能源潮流,提出基于时间序列与耦合分析的区域综合能源系统多能潮流计算方法。首先,利用时间序列分析该系统的调频特性,获取该系统的运行频率,并构建区域综合能源系统稳态网络模型。然后,分别计算电力系统与热力系统潮流,并通过电热耦合分析,得到该系统多能潮流计算结果。最后经实验验证:该方法可以精确计算热力系统中不同管道的供热温度与回热温度,还能够计算得出电力系统运行时的电压、有功功率与无功功率,实现较为全面的多能潮流计算。
英文摘要:
      Due to the existence of power and thermal energy in regional integrated energy system, it is difficult to couple and analyze multiple energy flows. A multi-energy flow calculation method of regional integrated energy system based on time series and coupling analysis is proposed. Firstly, the frequency modulation characteristics of the system are analyzed by using time series to obtain the operation frequency of the system. Steady- state network model of regional integrated energy system is constructed. Secondly, power flow of power system and thermal system is calculated respectively and through electrothermal coupling analysis, multi-energy power flow calculation results of the system are obtained. Finally, experimental results show that this method can accurately calculate the heating temperature and regenerative temperature of different pipelines in the thermal system, and can also calculate the voltage, active power and reactive power during the operation of the power system, so as to realize a more comprehensive multi- energy power flow calculation.
