摘　　要：在数字化转型促进新型电力系统高质量发展的背景下,研究了新型电力系统的数字孪生技术投资策略,识别了新型电力系统企业投资数字孪生技术的边界,构建了由发电商和售电商组成的二级电力供应链。通过逆向归纳法求解,对均衡解进行分析。研究发现,发电商投资数字孪生技术总是优于售电商投资;随着数字孪生技术投资成本的增加,电力需求量、数字孪生技术投资量、零售电价和发电商利润均会下降;随着数字孪生技术使发电商生产成本的减少比例增加,两种模型下的电力需求量、数字孪生技术投资量、发电商和售电商利润也会增加。Under the background of the national promotion of digital transformation to promote the highquality development of new electricity system,this paper studies the digital twin technology investment strategy of new electricity system,in order to identify the best investment strategy of upstream and downstream enterprises in the electricity supply chain.A secondary electricity supply chain consisting of generators and sellers is constructed,solved by backward induction,and the equilibrium solutions are analyzed by comparision.Investment in digital twin technology by generator is always better than electricity seller.As the cost of investing in digital twin technology increases,the demand for electricity,the amount of digital twin technology investment,the retail price of electricity,and the profits of generator will all decline.As the digital twin technology reduces the production cost of generator by an increasing proportion,under both models,the electricity demand,the amount of digital twin technology investment,and the profits of generator and electricity seller will also increase.

关 键 词：新型电力系统 数字孪生技术 电力供应链 博弈论
