摘要:
为了有效利用天然气传输调压过程中的压力能,给出了一种基于综合利用压力能发电和冷能参与的综合能源系统方案。 首先,考虑天然气压力能存在发电与制冷两种利用形式,建立了含天然气压力能利用的电-热-气冷综合能源系统模型;其次,建立了以系统日运行成本费用最小为目标函数的经济优化调度模型,包含购电成本、购气成本和设备运维成本等;最后,基于 MATLAB 平台,调用 CPLEX 求解器对该混合整数非线性优化模型进行求解。 结合某实际工业园区的运行数据,验证了所提模型的经济性与有效性。 结果表明:与不引入天然气压力能利用相比,所提模型可降低 74. 9%的系统运行成本,具有良好的经济效益。
Abstract:
In order to make effective use of the pressure energy in the transmission and regulation process of natural gas networks, a integrated energy system scheme involving the comprehensive use of power generation and cold energy of the natural gas pressure was proposed. Firstly, considering that natural gas pressure energy could be used with power generation and refrigeration, a model of electricity-heat-gas-cold integrated energy system containing natural gas pressure energy was established. Secondly, an economic optimization scheduling model with the minimum daily operating cost as the objective function was proposed including the cost of power purchase, gas purchase and equipment operation and maintenance, etc. Finally, the mixed-integer nonlinear optimization model was solved based on MATLAB platform combined with CPLEX solver. The economy and effectiveness of the proposed model were verified with the operation data of a real industrial park. The results showed that the operating cost of the system could be reduced by 74. 9% compared with no natural gas pressure energy utilization, and the system could obtain a good economic benefit.
