摘　　要：为推进我国能源生产革命,深入发展光伏发电势在必行。在去补贴的形势下,分时电价为光伏发电提供了新的收益点。分析了现行的分时电价政策及大工业用户投资光伏发电的优势,建立了光伏发电的全寿命周期经济性模型,以平准化度电成本、内部收益率、投资回收期为经济性评估指标,分析了典型地区大工业用户投资光伏发电的经济性。结果表明,各地区的光伏发电项目均可实现盈利,且分时电价可显著提高其经济性;电价水平越低,光伏发电的经济性越差,但光照资源丰富可一定程度上弥补电价水平的影响;分时电价的时段划分影响光伏发电的经济性,光伏发电时段内包含高峰电价的时间越长、越集中于发电量最大的时段内,光伏发电的经济性越好;电价的逐年下降将降低光伏发电的经济性,在投资决策时有必要充分考虑电价的变化趋势。In order to promote the energy production revolution,it is imperative to develop photovoltaic power generation.Under the situation of de⁃subsidy,time⁃of⁃use policy provides a new revenue point for photovoltaic generation.The current time⁃of⁃use policy and the advantages of large industrial users investing photovoltaic generation are analyzed.A life cycle economic model of photovoltaic generation is built.The economic performance of photovoltaic generation invested by large industrial users in typical areas is analyzed with the levelized cost of energy,internal rate of return and payback period as economic evaluation indicators.The results show that photovoltaic generation in all areas can profit,and the time⁃of⁃use pricing policy can significantly improve its economy.The lower the electricity price level is,the worse the economy of photovoltaic generation will be.but the abundant radiation resources can compensate for the impact of electricity price level to a certain extent.The time division of time⁃of⁃use pricing policy affects the economy of photovoltaic generation.The longer the photovoltaic generating period contains the peak price and the more concentrated it is in the maximum power generating period,the better the economy of photovoltaic generation will be.The annual decline of electricity price will reduce the economic performance of photovoltaic generation,which makes it necessary to fully consider the changing trend of electricity price when making investment decisions.
