Abstract

In this paper, the quantitative flexibility of EH is evaluated considering a flexibility index which is based upon available maximum capacity as well as the response time of generating units. Here, the impact of simultaneous EH operation and construction are investigated on quantitative flexibility considering both uncertain supply and demand side resources. Hence, a new structure so-called multi-objective simultaneous operation/construction optimization of multi-carrier EH is presented which consists of a decrease in operation and construction costs as well increase in power system flexibility. The demand side uncertainties, including thermal/electrical demand, are implemented by the Gaussian distribution function, and uncertainty on the supply side, including gas pressure uncertainty (GPU), is modeled by the probabilistic–possibilistic Z-number method. Also, in multifarious cases, the performance of the proposed index is evaluated. It is shown how flexible resources like electrical storage systems (ESS), thermal storage systems (TSS), electrical demand response programs (EDRP), and thermal demand response programs (TDRP) can increase the flexibility of the EH. It is also conducted that how the flexibility enhancement can increase construction costs.

考虑不确定供需侧资源的能源枢纽同步运行与建设定量灵活性研究

本文考虑了基于最大可用容量和机组响应时间的柔性指标，对电力系统的定量柔性进行了评价。在此，考虑不确定的供给侧和需求侧资源，研究了EH同时运行和建设对定量灵活性的影响。在此基础上，提出了一种多载波EH多目标同时运行/建设优化的新结构，该结构既降低了运行和建设成本，又提高了电力系统的灵活性。需求侧的不确定性(包括热/电需求)采用高斯分布函数实现，供应侧的不确定性(包括燃气压力不确定性(GPU))采用概率-可能性z数方法建模。此外，在各种情况下，所提出的指标的性能进行了评估。它显示了灵活的资源，如电力存储系统(ESS)、热存储系统(TSS)、电力需求响应程序(EDRP)和热需求响应程序(TDRP)如何增加EH的灵活性。并分析了柔性增强对建筑成本的影响。
