摘要
结合实际调研的工业园冷、热、电负荷情况,通过研究分析提出了总体设计方案,介绍并计算了分布式能源系统的各种经济性指标,建立了财务分析数学模型,从经济角度论证该分布式能源系统的可行性。结果表明该方案技术经济性良好,系统对能源价格体系中的电价、气价变化最为敏感,且存在临界电价和气价,当现有能源价格在临界范围内时,联供系统才具有一定的经济适用性。
An overall design is proposed through the research and analysis, combining with the actual survey of cold, heat and electrical load in the industrial park. Various economic indicators of distributed energy system are introduced and calculated, establishing a financial analysis mathematical model. From the aspect of economy, it demonstrates the feasibility of distributed energy system.The results show that the technical and economic effect of this system is good, and the system is more sensitive to the prices change of electricity and gas. It points out that critical electricity and gas prices exist in the system. When energy price is in the critical range, the system has an economic applicability.
