【摘要】：建立了分布式能源系统模型并以内部收益率为评价指标建立了经济评价模型,以上海、广州和北京三地的现有上网电价、购电价格和天然气价格为准,分析了补贴政策对三个城市分布式能源系统内部收益率的影响,结果发现现有条件下三地系统的投资回报均不佳。而后在不考虑补贴政策的条件下,为取得较好的投资回报,分析了系统在不同购电价格下的合理的上网电价和天然气价格区间,该结果可用于指导三个地区分布式能源系统上网电价和天然气价格政策制定。研究发现,相比较而言,广州投资建设天然气分布式能源系统更具潜力。而在三个城市现有的购电价格下,针对本文研究的系统,天然气价格不超过2.8元/m~3,上网电价不低于0.8元/(k W·h)时,系统才会有一定的投资回报。
[Abstract]:The distributed energy system model is established and the economic evaluation model is established with the internal rate of return as the evaluation index. The price of electricity, electricity purchase and natural gas in Shanghai, Guangzhou and Beijing are taken as the basis. This paper analyzes the effect of subsidy policy on the internal rate of return of distributed energy systems in three cities. The results show that the return on investment of the three systems is not good under the existing conditions. Then, in order to obtain a better return on investment without considering the subsidy policy, This paper analyzes the reasonable price range of electricity and natural gas under different purchase prices of the system. The results can be used to guide the policy making of electricity price and natural gas price in the distributed energy system in three regions. Guangzhou has more potential to invest in the construction of a natural gas distributed energy system. However, under the existing electricity purchase prices in three cities, the natural gas price of the system studied in this paper does not exceed 2.8 yuan / mm3, and the Internet electricity price is no less than 0.8 yuan / / kg W 路h). The system will have a return on investment.
