Under the guidance of the "dual carbon" goal

modern power systems require a higher proportion of new energy support

which puts higher demands on the flexible regulation capability of the power grid. Pumped storage

as a modern large-scale

technologically advanced

and long-life physical energy storage method

plays an important role in electricity storage

system peak shaving

frequency support

and other aspects. As a modern power control hub

intelligent substations are constantly upgrading towards digitization and networking. In this regard

the research focuses on the technical composition of pumped storage energy and the current research status at home and abroad

with a focus on exploring the integration path of intelligent substations in engineering application modes

operation mechanisms

and other aspects. The core applications of intelligent substations in efficient consumption

voltage support

black start

and fault emergency response are analyzed

which has great engineering value and practical significance for promoting the construction of new power systems and ensuring the implementation of the "Dual Carbon Strategy".
