中文摘要:电网未来态调度数字化举措的效果分析研究存在不足，这已成为制约电网调度数字化转型的重要因素。提出一种面向电网未来态调度数字化举措的效果分析方法，为电网企业在该地区的未来态调度数字化部署提供支撑。剖析了电力调度传统方法在当前环境下的局限性；结合不同极端气候突发情况构建极端场景下的数字化调度模型，以此分析极端场景中电网的调度效果；通过搭建未来态调度效果分析模块，对电网实施数字化举措的效果展开分析；借助 309 节点系统进行电网调度仿真，验证电网未来态调度举措的效果。仿真结果表明，电网未来态调度可有效提升电网韧性，降低电网及社会层面的损失。

Abstract:The insufficient research on the effect analysis of digital initiatives in future-oriented power grid dispatching has become a significant factor restricting the digital transformation of power grid dispatching. To fill this gap，this paper proposes a dedicated effectiveness-analysis method for future-oriented power grid dispatching to support power grid companies in their deployment of future-oriented digital dispatching in the region. First，the limitations of traditional power-dispatch methods under current operating conditions are dissected. Next，by integrating various sudden extreme-climate scenarios，a digital dispatch model under extreme conditions is constructed to quantify dispatch performances in such events. Furthermore，by building a future-oriented dispatching effect analysis module，the effect of implementing digital initiatives in the power grid is analyzed. Finally，a power grid dispatching simulation is conducted using the 309-bus system to verify the effect of future-oriented power grid dispatching initiatives. The results show that future-oriented power grid dispatching can effectively improve power grid resilience and reduce losses at both the power grid and social levels.
