On the Outward Transmission and Consumption of Hydro-Wind-Photovoltaic Power in the Lower Reach Area of the Jinsha River
The lower reach area of the Jinsha River is of abundant hydro-wind-photovoltaic power resources.Relying on the existing cross-province direct current outward transmission channels of the cascade hydropower stations,a combined outward transmission and coordinated consumption of the hydro-wind-photovoltaic power can be realized.With the analy-sis of the load characteristics of the power grids in the receiving ends,calculation methods for the maximum and mini-mum consumption space is proposed.Taking the practical data of 2021 as an example,the consumption capacity of each receiving province and city for the new energy in the lower reach area of the Jinsha River is analyzed.The results show that Guangdong Province has the largest consumption space,while Shanghai has the smallest.Due to the internal load characteristics of different provinces and cities and the power generation characteristics of the outward transmission power stations,the months with larger space for new energy consumption are different.Overall,Jiangsu,Zhejiang and Guang-dong Province have higher consumption capacities in the dry season than the flood season,while Guangxi Province has a slightly higher consumption capacity in the flood season than the dry season.The results can provide reference for the cross-province consumption of clean energy in the lower reach area of the Jinsha River.
