中文摘要:目前，对配电网数字化效果分析研究多停留在宏观层面，缺乏数字化措施影响下配电网运行的精细化模型构建。针对这一问题，提出了一种配网“源网荷储融合互动”数字化效果分析模型。首先，分析不同数字化措施会对配电网运行产生的影响；其次，构建3种不同数字化配置的配电网运行场景，并建立与之匹配的分析模型与流程；再次，通过模型仿真获得配电网运行结果；最后，分析其数字化措施投入前后配电网的线损减少量、线路负载率及新能源消纳增量，以得出配电网“源网荷储融”数字化的效果。结果表明，该模型可有效评估数字化在降低线路损耗、提升新能源消纳水平及缓解线路负载压力方面的成效。

Abstract:At present，research on the digital effect analysis of distribution networks mostly remains at a macro level，lacking the refined modeling for the operation of distribution networks under the influence of digital measures. To address this issue，a digital effect analysis model for "source-grid-load-storage integration and interaction" in distribution networks is proposed in this paper. First，the impacts of different digital measures on the operation of distribution networks are analyzed. Second，based on the operational differences of distribution networks，three operation analysis models and corresponding analysis processes for distribution networks under different digital measure scenarios are constructed respectively. Third，the operational results of distribution networks are obtained through model simulation. Finally，the line loss reduction，line load rate and new energy consumption increment of distribution networks before and after the implementation of digital measures are analyzed to derive the digital effects of "source-grid-load-storage integration and interaction" in distribution networks. The results show that the proposed model can effectively evaluate the effectiveness of digitalization in reducing line losses，improving the level of new energy consumption and alleviating the line load pressure of distribution networks.
