Configuration Optimization Method of Hybrid Energy Storage for Desert-Gobi-Wasteland Renewable Energy Bases Considering Retrofit of Molten Salt Heat Storage Coupled With Thermal Power Units
摘要
Abstract
Large-scale renewable energy bases in desert,Gobi and wasteland areas are being developed and constructed at an accelerated pace.In order to enhance the adjustment flexibility of power systems and promote the high-level accommodation of renewable energy,this paper proposes an configuration optimization method of hybrid energy storage(HES)for Desert-Gobi-Wasteland renewable energy base(DGW-REB)considering retrofit of molten salt heat storage coupled with thermal power units(MSHS-TPU).Firstly,for DGW-REB integrated with electrochemical energy storage and molten salt heat storage,the basic principle and internal energy flow relationship of MSHS-TPU are analyzed,and a mathematical model for system operation analysis is subsequently established.Considering the impact of carbon emission trading on the configuration optimization of energy storage,a two-layer configuration optimization model of electric-thermal HES for DGW-REB is developed,with the upper-layer model forming configuration scheme of HES with the minimum life cycle cost,and the lower-layer model forming operation cost.Finally,the effectiveness of the proposed method is verified through a case study of a large-scale renewable energy base in the Kubuqi desert of China.The research results are expected to provide valuable references for the development and construction of DGW-REBs.关键词
