With the growing global focus on renewable energy

electrified transportation has also developed rapidly. However

its integration into large-scale power grids imposes significant load impacts

posing challenges to the operation and dispatching as well as planning and design of power systems and affecting the continuous and stable operation of power grids. To address this

this paper establishes a multi-dimensional evaluation model from three perspectives: voltage stability

load distribution

and power quality

studies the complex impact mechanism of transportation electrification on power grids

and proposes targeted optimization strategies. It aims to provide important theoretical and technical support for the safe

stable

and efficient operation of power grids

promote the coordinated development of electrified transportation and power systems

and contribute to the global energy transition and sustainable development.
