With large-scale distributed energy integration

the frequency of the power system is more outstanding

and demand response can provide solutions to this problem.Based on the demand side for evaluating the feasibility of frequency modulation

frequency modulation method as a starting point

on the demand side response in system FM research were summarized.First of all

it may take part in the load characteristic of the system frequency， and types of demand response are analyzed

which provide an overview of different types of demand response frequency modulation control strategy and modeling method.The paper introduces the demand of the new energy access response FM capability assessment method

finally combining the development of electric power system in China

it puts forward the demand side of FM promotion proposal.
