The invention discloses a boiler heat storage parameter identification method and system. The boiler heat storage parameter identification method comprises the steps that a turbine model is acquired or selected; a parameter is identified and acquired according to the turbine model; the transfer function of the turbine is calculated according to the acquired parameter; the reciprocal of the transfer function of the turbine is calculated; a main steam flow is acquired according to engine power and the transfer function of the turbine; a boiler model is acquired or selected; the main steam flow is adopted as the input for calculation through the boiler model; main steam pressure change is adopted as the output for parameter identification so as to acquire the boiler heat storage parameter; byadopting the boiler heat storage parameter identification method and system, the transfer function of the turbine is acquired; the engine electric power in the testing process is multiplied by the reciprocal of the acquired
