Analysis on the Complementarity of Hydro,Wind and Solar Energy Resources in the Upper Yellow River
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.
