燃气发电的发展及其对电网调峰和经济性影响研究

中国燃气电站大规模发展面临气源、气价和系统调峰等多种约束,需要深入研究气电发展及其对电网调峰和经济性的影响。提出了燃气电站规划研究的原则和方法,以系统电力供应总成本最小为目标,以电力电量平衡、燃气等能源供需平衡、系统建设和运行等各种要求为约束条件,研究总体电源规模和结构,包括燃气电站建设规模。在此基础上,综合考虑燃气电站前期工作进展情况、气源落实情况以及系统调峰平衡状况,提出地区电网燃气电站推荐装机容量并进行经济性分析,为地区电网制定燃气电站发展规划提供参考。

Development Planning of Natural Gas Power Generation and Its Influence on Power System's Peak Load Regulation and Economy

The large-scale development of natural gas power generation in China is subject to natural gas supply, price and peak load regulation, etc. It is important to research natural gas power generation’s planning and its influence on power system and its economy. The principle and method of natural gas power generation’s planning is proposed. Based on the minimum total system cost of the power supply, with the constraints of power system’s construction ans operation, balance of power and energy, balance of natural gas demand and its supply, etc., the recommended scenario of total generation development planning scale and its structure is proposed, including natural gas power generation’s scale. Furthermore, considering natural gas power station’s preliminary work, natural gas supply and system peak load regulation, the recommended scale of natural gas power generation and its economy is proposed. The study conclusion provides the guidance for the development of the natural gas power generation in China.
