摘要
基于能源集线器模型建立分布式综合能源系统可靠性评估模型,刻画不同供能子系统之间的复杂互连对可靠性的影响。针对负荷的动态行为,建立电热水负荷模型分析其对供能可靠性指标的影响。通过马尔可夫链蒙特卡洛法对配电网下的分布式综合能源系统进行可靠性评估,计算其可靠性指标。算例分析结果表明:供热可靠性指标修正方法可有效计及热负荷动态行为对供热可靠性指标的影响;DIES可靠性评估方法可有效衡量DIES可靠性水平,且DIES内各形式能源的耦合程度与系统可靠性直接相关。
The establishment of Distributed Integrated Energy System （DIES） reliability evaluation model is based on Energy Hub model. The model describes the effect of the complex interconnection between difference power supply subsystems on system reliability. The electric water heating load model is established to analyze the effect of load dynamic behavior on the reliability indices of energy supply. A Markov Chain Monte Carlo （MCMC） method is used to evaluate the reliability of distributed integrated energy systems under distribution system, and the reliability indices have been calculated. The results of numerical tests show that the method proposed in this paper can effectively take into account the effect of the dynamic behavior of thermal load on thermal supply reliability indices, and effectively measure the reliability level of DIES. And the degree of coupling between the energy supply subsystems in DIES is directly related to the system reliability.
