摘要
Abstract
The terrain of Hubei Province is an incomplete basin,surrounded by mountains in the east,west and north,low and flat in the middle,and slightly open to the south.Naturally,it has the topographic height difference and sufficient water resources required for the construction of pumped-storage power stations.From the perspective of site distribution,pumped storage sites in Hubei Province are basically located in the western,northern and Dabieshan Mountain area,especially in the western mountain area,the sites are the most abundant,while in the central Jianghan Plain,the sites are relatively less.The analysis results show that,for 2030,Hubei Province will not require additional external electricity,but an additional 7.6 GW of energy storage is needed to fill the power gap,and in this case,the renewable energy consumption rate can achieve 96.2%;for 2035,both power and energy gaps are filled by the combined supplementation of energy storage facilities and external power,in which,the total demand for energy storage in 2035 is 19.91 GW based on multiple scenarios simulation and economic analysis,and in this case,the renewable energy consumption rate will exceed 95%and the annual cost is lowest.Further analysis of the regional power market indicates that,by 2035,the energy storage demand for eastern Hubei will be 8.4 GW,the energy storage demand for western Hubei is 6.9 GW,and a reasonable energy storage demand for northwestern Hubei is 4.61 GW.Overall,the distribution of pumped storage resources in Hubei Province aligns with demand to a certain extent,and future layouts of pumped storage and new energy storage should focus on the eastern and northwestern Hubei Province.关键词
