Power system evaluation method, device, equipment, storage medium and product

The invention provides a power system evaluation method, device and equipment, a storage medium and a product, and the method comprises the steps: building a joint probability prediction model for different prediction time scales of a to-be-evaluated time period in the future through considering the random volatility of uncertain power output and load demand, and the mutual influence between the uncertain power output and load demand; generating probability distribution of an uncertain electric quantity net difference in a to-be-evaluated time period by using working state information of an uncertain power supply and a load in a time dimension provided by a joint probability prediction model and an operation scheduling plan, and considering the net difference of the uncertain electric quantity and the load; and the unbalanced distribution condition of the electric quantity of the whole electric power system is accurately predicted, so that accurate data support is provided for dispatching and operation of the
