面向电力系统需求响应的5G基站可信容量评估与优化调度研究综述OA

[Objective]With the rapid advancement of the fifth-generation(5G)mobile communication technology,large-scale deployed 5G base stations with high energy consumption characteristics exhibit considerable demand response potential,serving as an indispensable solution for the transformation of new power systems.Nevertheless,most existing studies assess the dispatchable potential of 5G base stations based on deterministic models,which fail to fully account for multiple uncertainties including communication load fluctuations and power supply reliability,thus undermining the reliability and accuracy of evaluation results.[Methods]This paper firstly reviews the traditional deterministic assessment methods and systematically analyzes their inherent limitations.Combined with the operational characteristics of 5G base stations,a credible capacity assessment framework considering multiple uncertainties is further proposed.On this basis,the credible capacity evaluation of 5G base stations is incorporated into power system optimal scheduling,and a stochastic optimal scheduling strategy constrained by credible capacity is formulated.Finally,future research directions for the collaborative scheduling of 5G base stations and power systems are prospected from three dimensions:source-load uncertainty,cross-level resource collaborative optimization,and data security protection.[Results]The results demonstrate that the proposed credible capacity assessment method can quantify the adjustable regulation capacity of 5G base stations at different confidence levels.Introducing the assessment results as credible constraints into the optimal scheduling model effectively enhances the adaptability of scheduling decisions to complex and variable operating conditions.[Conclusions]In future research,it is necessary to further deepen the collaborative research on credible capacity assessment of 5G base stations and optimal scheduling of power systems.The research findings can provide a solid theoretical foundation for the reliable participation of 5G base stations in power system scheduling,and facilitate the safe,stable operation and low-carbon transformation of new power systems.
