Cooperative scheduling method, system and equipment for flexible resources on both sides of source and load, and medium

The invention provides a source-load double-side flexible resource cooperative scheduling method, system and device and a medium, and the method comprises the steps: obtaining the day-ahead operation parameters of a conventional unit, and the deep peak regulation parameters of a coal power unit and a demand response resource, building a peak-regulation-free power generation pre-scheduling model according to the parameters, and calculating the peak regulation demand of each preset time period; establishing a deep peak regulation model for collaborative optimization of the coal power units and the demand response resources according to the peak regulation demand quantity, the coal power units and the deep peak regulation parameters of the demand response resources, and calculating to obtain the peak regulation output of the coal power units participating in deep peak regulation in each peak regulation demand period and the peak regulation output of the demand response resources; and establishing a peak regulati
