摘要
冷热电蓄能联供微网系统具有环保、节能、经济等特点,有着良好的发展前景和应用价值。但存在多方面因素不同程度地影响着系统的优化配置结果。以经济性为优化目标,构建冷热电蓄能联供的微网系统优化模型,运用DER-CAM软件对系统进行优化仿真测算。分析了燃气价格、电价和分布式能源投资三个关键因素对优化配置的影响。通过应用DER-CAM软件的优化仿真测算得出结论,在5%的变动率范围内,电价是最为敏感的因素,当变动率超过5%后,分布式能源投资成为最敏感因素。
Combined cooling heating and power （CCHP） system has the characteristics of energy saving and environ- ment protection. In process of optimization for CCHP, many factors will influence the result of the system configuration in different degree. In order to optimize the economy, an optimization model for the CCHP system is constructed, and the simulation calculation for the system is obtained by using the DER-CAM software. Meanwhile three key factors of the gas price, the electricity price and distributed energy investment are analyzed to influence the optimization results. By applying the DER - CAM software to optimize the simulation calculation, the main conclusion is that the most sen- sitive factors is the electricity price in the changing rate of 5%, and the most sensitive factor is distributed energy in- vestment when the changing rate is above 5%.
