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.
