摘要
水风光多能互补是促进新能源消纳、促进能源系统绿色转型的创新模式.分析水风光能源资源的互补性对于水风光互补系统的科学规划具有重要意义.论文以黄河上游千万千瓦级水风光互补清洁能源基地为研究对象,分析水风光能源资源多时间尺度的互补性.结果表明:黄河上游风光出力在日内和年内的互补性均较弱;而水风、水光在年内的互补性较强,且水风互补性强于水光;水、风、光三种能源之间具有互补性,论证了实施水风光一体化的必要性.
Abstract
The complementary operation of hydro,wind and solar energies is an innovative mode to promote the consumption of new energy and the green transformation of the energy system.Analyzing the complementarity of hydro,wind,and solar energy resources is of great significance to the scientific planning of the complementary system.In this paper,we analyzed the complementarity of hydro,wind and solar energy resources at multiple time scales fora 10 million kilowatt-level clean energy base in the upper Yellow River.The results indicate that:(1)the complementarity of wind and solar power output within the day and year is weak;(2)the complementarity between hydro and wind,hydro and solar are strong within the year;and(3)the complementarity between hydro,wind and solar exist,highlighting the necessity to integrate hydro,solar and wind energies.
