Collaborative Optimization Configuration of Electric-thermal Hybrid Energy Storage for Desert-Gobi-Wasteland Renewable Energy Bases Considering Steam and Electricity Combined Heating Molten Salt Energy Storage
摘要
Abstract
China has accelerated the development and construction of large-scale renewable energy bases in desert gobi and wasteland areas to achieve the carbon peaking and carbon neutrality targets.In order to improve the economy and renewable energy utilization rate of energy bases,this paper proposes a collaborative optimization configuration method of electric-thermal hybrid energy storage for desert-gobi-wasteland renewable energy base considering steam and electricity combining heating molten salt energy storage(SE-MSES).Firstly,targeting desert-gobi-wasteland renewable energy bases equipped with electrochemical energy storage and molten salt energy storage,the basic principle of SE-MSES system is analyzed,and the retrofitting cost model and operation model of SE-MSES are constructed.Secondly,with the goal of maximizing the net income of renewable energy bases and minimizing the new energy curtailment rate,a collaborative optimization configuration model of electric-thermal hybrid energy storage for desert-gobi-wasteland renewable energy bases is established considering the power supply price mechanism.The two-stage optimization is performed based on typical scenarios and annual 8 760 h time-series production simulation.Finally,a renewable energy base located in the Kubuqi Desert of China is selected as the numerical example to verify the feasibility and effectiveness of the proposed method,and the impacts of factors including pricing types on the configuration results are quantitatively analyzed.The results demonstrate that the implementation of comprehensive on-grid electricity prices is conducive to promoting renewable energy bases to participate in power-market transactions as an integrated entity.关键词
