摘要
在向新型电力系统发展的过程中,综合考虑碳排放和系统灵活潜力释放的源网荷储互动模式,成为应对新能源消纳难题和实现“双碳”目标的必要形式。该模式通过在电力系统中精确匹配各方资源的时空维度,实现精准追踪和分析耦合的电流和碳流。为此从电力系统规划、互动关键技术、碳计量分析方法、模型与综合性能评价4个研究方面进行综述,发现目前电力系统在技术支撑性、减碳性能和整体性能评价方面存在一些问题,包括规划整体性不强、规划中对源荷不确定性考虑不足、技术体系效率不高、碳排放计量不准确、性能评价指标不完善等。未来的研究需要在以下几个方面进行深入探讨:提升基于低碳效益的源网荷储协同规划能力,推动关键技术的低成本应用,提高碳计量的精度,深入研究电碳耦合机理和公平划分排放责任,构建能够反映新型电力系统特征的指标体系。期望这些研究有助于提升整个系统的灵活互动减碳能力。
In the transition towards the development of new power systems,the source-grid-load-storage interaction mode,which comprehensively considers carbon emissions and flexible potential release of the system,is a necessary form of development to address the challenges of new energy consumption and the dual carbon goal.This mode enables the accurate matching of resources within the power system in both temporal and spatial dimensions,and achieves the coupling of current and carbon flow through carbon measurement and analysis.This research aims to enhance flexible interactive carbon reduction capabilities of the entire system.Thus,this paper summarizes in four aspects of power system planning,the key technologies of interaction,carbon measurement analysis methods and the evaluation of model and integrated performance.It identifies several issues in the current power system,including weak planning integrity,insufficient consideration of low-carbon planning,inefficient technical system performance,inaccurate carbon emission measurement,and incomplete evaluation indicators for overall system performance.To address these challenges,it proposes to carry out further researches in several aspects,such as promoting the source-grid-load-storage cooperative planning,driving low-cost application of the key technologies,improving the accuracy of carbon measurement,studying the mechanism of electricity-carbon coupling and the fair division of emission responsibilities,and constructing an index system that reflects the characteristics of the new power system.It points out these further researches can help to promote flexible interactive carbon reduction of the overall system.
