| 摘要: |
| 区域综合能源系统包含的设备和负荷类型众多，设备之间的耦合方式多样，在实际运行中往往难以确定最优的供能方式。从能耗分析的基本原理出发，结合带时间约束的模糊有色Petri网特定的建模原则，提出一种区域综合能源系统能耗优化推理模型。该模型在满足负荷需求和基本运行条件下，从综合能源系统运行成本、污染物排放量和一次能源消耗量3个方面对系统供能路径进行优化，通过对系统进行能耗仿真分析，从而得到不同需求场景下的最优供能方式。最后以某实际区域综合能源系统为例，验证了所建模型的有效性和实用性。 |

| Abstract: |
| The regional integrated energy system contains many types of equipments and loads, and the mode of coupling among the equipments is diverse, so it is often difficult to determine the optimal power supply mode in actual operation. Based on the basic principle of energy consumption analysis and the specific modeling principle of temporal fuzzy colored Petri net, an energy consumption optimization inference model of regional integrated energy system is proposed. The proposed model optimizes the energy supply path of the integrated energy system from three aspects of operating cost, pollutant emissions and primary energy consumption under the load demand and basic operating conditions. The optimal energy supply mode under different demand scenarios is obtained by simulating the energy consumption of the system. Finally, the effectiveness and practicability of the proposed model are verified by taking a practical regional integrated energy system as an example. |
