Method and terminal for virtual power plant to participate in frequency modulation transaction control

The invention discloses a method and terminal for a virtual power plant to participate in frequency modulation transaction control, and the method comprises the steps: building a frequency modulation performance evaluation model of the virtual power plant, and employing a piecewise linear regression fitting method for the frequency modulation performance evaluation model; evaluating the frequency modulation performance of each frequency modulation resource participating in the frequency modulation transaction application through the frequency modulation performance evaluation model; during frequency modulation transaction pre-clearing, according to the type of each frequency modulation resource and the frequency modulation performance obtained by evaluation, adjusting the frequency modulation pre-clearing output upper and lower limits of each frequency modulation resource in the virtual power plant; decomposing an output index according to the upper limit and the lower limit of the pre-clearing output to obta
