摘要: 摘要:受天然气价格与上网电价等因素的影响,天然气发电缺乏足够的竞争力。目前我国天然气发电执行的是临时上网电价,没有体现资源稀缺、环境保护等外部成本。分析了天然气价格、年利用小时数对天然气发电经济性的影响。在考虑发电峰谷分时电价和环保价值的前提下,对天然气发电与煤电的经济性做对比,测算后提出合理的上网电价,为天然气发电产业发展提供参考。

Abstract: Abstract:Under the impact of the natural gas price, the feedin tariff and other factors, the natural gas power generation has not sufficient competitiveness. In our country, the current ongrid price of the gas power generation is the temporary ongrid price, which does not reflect the scarce resource, the environmental value and other external costs. The influences of the natural gas price and annual utilization hours on the economic efficiency of gas power generation were analyzed. Considering the peakvalley timeofuse power price and the environment value, the economic benefit of the gas power generation and the benefit of coalfired power generation were compared. Based on a guess and estimate, the rational grid purchase price of the gas power generation was put forward, which provides a reference for development of the gas power generation industry.
