| 摘要: |
| 在综合能源系统中，建立合理有效的优化配置模型是实现系统经济运行和多能源供需平衡的关键。针对园区综合能源系统，提出一种考虑设备变工况特性和系统灵活性供需匹配的优化配置模型。考虑系统中设备能效的不确定性，建立其受多因素影响的变工况特性模型；为提升系统应对可再生能源输入及负荷需求不确定性的能力，提出灵活性供需匹配指标；以系统配置成本最优为目标、灵活性供需匹配指标为约束，建立园区综合能源系统优化配置模型。最后，以北方某园区为例进行仿真分析，结果表明在系统优化配置中考虑设备的变工况特性和灵活性供需匹配程度，可进一步提高系统配置的科学性和合理性。 |

| Abstract: |
| The establishment of reasonable and effective optimal allocation model is important for the economic operation and multi-energy supply-demand balance in the integrated energy system. Thereby, an optimal allocation model is proposed considering the off-design performance and the flexible supply-demand matching for the community integrated energy system. The off-design performance model of equipment affected by multiple factors is proposed, in which the uncertainty of equipment energy efficiency in the system is considered. Then, the flexible supply-demand matching index is developed to improve the system’s ability for coping with the uncertainty of renewable energy generally and power demand. The optimal allocation model of community integrated energy system is developed to minimize the system allocation cost, in which the constraint that corresponds to flexible supply-demand matching index is taken into account. Finally, a community integrated energy system in northern China is taken as an example for simulation analysis. Simulative results show that the system allocation can be scientifically and reasonably optimized considering the off-design performance and the degree of flexible supply-demand matching. |
