The present application provides a load recovery model generation method, device, computer equipment and storage medium, which relate to the technical field of electric power automation. The method includes: establishing a load restoration model according to the access state parameters and predicted output value of the wind farm to be restored, the restoration state parameters of the power-off load, and the predicted active power; The main model in the forecast scenario and the sub-model in the error scenario are obtained by coupling; according to the predicted output value and predicted active power, the main model is solved to obtain the load restoration plan in the forecast scenario, and the first uncertainty set of forecast error and the second uncertainty set are obtained. The second forecast error uncertainty set, according to the load restoration plan, the first forecast error uncertainty set and the second forecast error uncertainty set, solves the sub-model, and if the solution result of the sub-model satisfies the preset restoration condition, the load restoration plan is output. The load recovery process can be made safer by this application.
Description
technical field [0001] The present invention relates to the technical field of electric power automation, in particular to a method, device, computer equipment and storage medium for generating a load restoration model. Background technique [0002] With the rapid development of wind turbine manufacturing and control technology, the wind power grid-connected capacity is increasing year by year. When a large-scale blackout occurs in a system with high wind power penetration rate, how to arrange the safe and fast recovery of load is a new problem that needs to be studied and solved urgently. [0003] Existing schemes propose a source-load coordinated recovery method that considers wind farms participating in load recovery. Wind turbines have the advantages of small start-up power requirements and fast start-up speed, and timely connection can help speed up the system recovery process. [0004] However, under the constraints of random changes in wind speed, wind turbines cannot...
