Under the wave of global energy transformation

the energy storage system has become a core facility to balance electricity supply and demand and improve new energy consumption. With its large-scale grid connection

the importance of the grid-connected protection device for energy storage systems is increasingly prominent. However

due to the complex operation characteristics of the energy storage system

it is difficult to fully adapt the existing grid technical specifications

resulting in frequent problems such as protection misoperation and poor communication. Therefore

it is urgent to carry out adaptability analysis and research. This article deeply analyzes the adaptability of the existing technical specifications of the power grid for the grid connection protection device of the energy storage system

and discusses the strategies and methods to improve adaptability

and provides the theoretical basis and technical support for the safe and reliable grid connection of the energy storage system.
