摘要
发展天然气发电对于推动地区优化能源结构、促进节能减排、实现“双碳”目标具有重要意义。天然气发电机组凭借环保、快速启停等优点,已越来越多地应用于电力系统调峰调频。对于峰谷差明显、长期存在调峰压力、即将大规模接入海上风电等间歇性可再生电源的某东部沿海省份电力系统而言,“十四五”期间及以后建设一批调峰气电意义重大。随着东部地区天然气供应能力的逐步增强,天然气发电已具备良好的建设基础。气电的合理规模与布局、电源与电网的协调发展,共同保障电力安全供应、增强电力系统稳定水平。天然气发电机组其清洁高效、启停迅速、运行灵活、调节性能好的优点,而不同类型的天然气发电机组在技术性能、碳排放、度电成本等方面具有不同的特点,因此为促进天然气发电高质量发展,结合天然气发电机组的发展趋势及电网调峰需求,本研究拟对某东部沿海省份未来天然气发电机组选型进行研究。
The development of natural gas power generation holds significant importance in promoting regional optimization of energy structure,facilitating energy conservation and emission reduction,and achieving the“carbon peaking and carbon neutrality”goal.Natural gas power generation units,with their environmental friendliness and fast start-stop capabilities,have increasingly been employed in peak load regulation and frequency control in the power system.For an eastern coastal province in China,characterized by significant peak-to-valley differences,long-term peak load pressures,and the upcoming large-scale integration of intermittent renewable energy sources such as offshore wind power,the construction of a batch of peak load gas-fired power plants during the 14th Five-Year Plan period and beyond carries great significance.With the gradual enhancement of natural gas supply capacity in the eastern region,natural gas power generation has established a solid foundation for development.The rational scale and layout of gas-fired power plants,as well as the coordinated development between power sources and grids,jointly ensure secure power supply and enhance the stability of the power system.Natural gas power generation units possess advantages such as cleanliness,high efficiency,rapid start-stop capabilities,operational flexibility,and good regulation performance.However,different types of natural gas power generation units exhibit distinct characteristics in terms of technical performance,carbon emissions,and electricity cost.Therefore,in order to promote the high-quality development of natural gas power generation,this study aims to investigate the selection of future natural gas power generation units in a certain eastern coastal province,taking into account the trends in natural gas power generation unit development and the demand for grid peak load regulation.
