基于四侧联合计算因子的新型电力系统评价及省域对比分析OA

[Objective]To address the limitations of existing evaluation frameworks for new power systems,such as the inadequate representation of"generation-grid-load-storage"synergy and overly simplistic evaluation dimensions,this paper develops a comprehensive evaluation system capable of scientifically quantifying the level of four-side collaborative development.[Methods]An evaluation matrix comprising 14 indicators across 12 aspects was constructed based on the five core characteristics of the new power system.A"four-side joint calculation factor"was innovatively introduced to deeply embed the collaborative relationships of generation-grid-load-storage into the indicator calculation process.The fuzzy analytic hierarchy process,combined with reference value methods,was employed to achieve a quantitative assessment of provincial-level systems.[Results]Case studies demonstrate that the framework effectively reveals developmental disparities between provinces.Province A leads in clean and low-carbon performance;however,its renewable energy installation structure results in poor generation-load temporal matching and insufficient flexibility resources.In contrast,Province B excels in supply-demand coordination and intelligent flexibility,though its energy transition progress and economic efficiency are relatively constrained.Sensitivity analysis confirms that new energy storage configuration,wind and solar installation scales,and demand response capacity are key factors influencing the overall system performance,validating the reliability and robustness of the proposed model.[Conclusions]The proposed evaluation system,based on the"four-side joint calculation factor,"achieves a precise quantitative characterization of collaborative development across generation,grid,load,and storage.It effectively identifies regional system bottlenecks and provides a quantitative basis for the planning,construction,and differentiated policy-making of new power systems.
