The invention discloses an optimization control method for assisting a thermal power frequency modulation unit to participate in a frequency modulation auxiliary service market by an electric vehicle. The method comprises the following steps: constructing a power grid frequency modulation frame cooperatively participated by the electric vehicle and the thermal power unit; frequency modulation capacity income, frequency modulation mileage income, generator set power offset cost and electric vehicle battery compensation cost are considered, and an income model is established with the purpose of maximizing the total income of frequency modulators; the charging station responds to the frequency modulation requirement in a zoning and grading mode according to the charge state of the electric vehicle, and the thermal power generating unit considers output and climbing constraints to respond to the frequency modulation requirement; and establishing a two-region interconnected power system simulation model containing the electric vehicle, and analyzing the frequency modulation performance in the step 3. According to the optimization control method for assisting the thermal power frequency modulation unit to participate in the frequency modulation auxiliary service market by the electric vehicle, the frequency response deviation can be effectively reduced, and the economic benefit of a frequency modulator is remarkably improved.
