| 综合能源系统以其独特的经济、环保和节能优势成为当前能源利用模式的主要发展趋势，然而其开发离不开仿真系统的支持。目前，市面上仅有对于单一能源网络的成熟商业化仿真软件，但支持综合能源系统多能流联合解算与分析的规范化软件尚未得到有效开发。针对以上问题，基于完善的综合能源设备及电-气-冷-热-蒸汽网络模型库，结合Java与Python语言采用B/S结构搭建以图元为导向的综合能源在线仿真系统。平台支持多种能流网络稳/动态仿真，可实现并行解算，效率高。利用算例进行常规态与故障态仿真，仿真结果符合网络与设备运行理论分析，证明了所搭建的软件系统支持运行可行性验证，有效实现多能流多运行状态仿真，功能强大，具备工程应用价值。 |
| 英文摘要: |
| Integrated energy system (IES) has become the main development trend of current energy utilization mode with its unique economic, environmental and energy - saving advantages.However, the development of IES is inseparable from the theoretical support of integrated energy simulation system. At present, there are only kinds of mature commercial simulation software for a single energy network on the market. However, the standardized software supporting the joint calculation and analysis of multi - energy flows in IES has not been developed effectively. Regarding the above points,based on the comprehensive model library of integrated energy equipment and networks with the multi- energy of electricity, gas,cooling, heating and steam, B/S structure is applied to build an element-oriented integrated energy online simulation system using Java and Python. The proposed simulation system supports the steady/dynamic simulation of multi - energy flows in energy networks, and can realize the parallel calculation with a high efficiency. Results of the case study simulated in the normal state and fault state are consistent with the theoretical analyses of the operation of networks and equipment, proving that the software system built can be used forthe verification of the operational feasibility of IES planning scheme and realizes the simulation of multi-energy flows under multiple operational states effectively. It has powerful functions and is of practical application value. |
