Collaborative optimization method for fast frequency modulation of light-fire-controllable load coupling system

The invention relates to a fast frequency modulation collaborative optimization method for a light-fire-controllable load coupling system, and the method comprises the steps: taking a load loss rate, carbon emission and a primary frequency modulation ITAE index as objective functions; taking an output power constraint, a photovoltaic power station standby constraint, a thermal power generating unit standby constraint and a load regulation capacity constraint as constraint conditions to establish a rapid frequency modulation optimization model of the coupling system, solving the model by adopting a multi-target bacterial foraging algorithm, and weighing a plurality of target functions to generate a Pareto solution set; the three frequency modulation resources of the photovoltaic power station, the thermal power plant and the controllable load can be operated cooperatively, the frequency modulation rapidity, stability and accuracy of the coupling system are improved, the carbon emission is effectively reduced,
