The electric heating load can provide a variety of auxiliary services to the power system

which can reduce carbon emissions while improving the stability of the power system.With the deepening of its research at home and abroad

its application scale has gradually expanded.Based on the research results at home and abroad

this paper summarizes the key technologies of electric heating load participating in power grid regulation from four aspects single electric heating model analysis

electric heating load group aggregation mode analysis

electric heating regulation ability evaluation and electric heating participating in power grid auxiliary regulation control mode.Finally

the key technologies of electric heating load participating in power grid regulation are summarized.Combined with the problems faced by the current technology

the three future research directions of improving the modeling accuracy of electric heating load

considering the income problem of the third party and optimizing the scheduling strategy are prospected.
