Temperature modulation market-oriented thermoelectric unit power output control method and system

The invention discloses a thermoelectric unit power output control method and system for a frequency modulation market, belongs to the technical field of power control, and provides a heat output adjustment amount for a thermoelectric unit by introducing a heat storage device to adjust the heat output of the thermoelectric unit so as to change the corresponding frequency modulation capacity of the thermoelectric unit in the frequency modulation market. Establishing a frequency modulation market optimization model; the process of solving the model is equivalent to searching in the direction of frequency modulation capacity increase corresponding to the thermoelectric unit in the frequency modulation market within the feasible region range of operation of the thermoelectric unit so as to search for the optimal heating power output adjustment amount, and therefore the optimal operation point of the thermoelectric unit in the frequency modulation market is obtained. And the optimal power output of the thermoelect
