摘要:  随着城市电网中电热等多类型负荷的持续增长,为保证高负载率情况下的可靠性水平,需要通过电热等能源的综合需求响应提升系统的供能可靠性。为此,文章提出了一种考虑多类型综合需求响应的电热耦合能源系统可靠性评估方法。首先,分析了电热耦合能源系统的基本结构以及所研究的边界条件。其次,介绍了电热耦合系统中不同元件的出力模型与状态模型。然后,建立了基于电价与基于激励2种模式下的电热综合需求响应模型,并以此为基础提出了故障影响分析的方法以及可靠性评估的流程。最后,通过实际算例比较了不同综合需求响应方案下的可靠性指标与经济性水平,以指导电网公司进行最优综合需求响应方案的选择,从而证明了所提方法的有效性和实用性。

Abstract: With the continuous growth of various electricity and heat loads in urban power grid, to ensure the system reliability under high loading rate, it is necessary to improve the energy supply reliability of the system through the integrated demand response considering electricity and heat. Therefore, a reliability assessment method for coupled electricity-heat energy system considering multi-type integrated demand response is proposed in this paper. Firstly, the basic structure of the coupled electricity-heat energy system and the boundary conditions are analyzed. Next, the output models and state models of different elements in the coupled electricity-heat energy system are introduced. Then, the integrated electricity-heat demand response models based on electricity price and incentive are established, and the FMEA method and reliability assessment process are presented. Finally, the reliability and economy indexes under different integrated demand response schemes are compared through a case study. The result is helpful for the grid companies to select the optimal integrated demand response scheme, which verifies the effectiveness and practicality of the method proposed in this paper.

Key words: coupled electricity-heat energy system, integrated demand response, time-of-use electricity price, incentive response loads, reliability assessment
