Abstract

The power recovery method and device provided in the present application are applied to power supply control equipment in a power supply system. The power supply control device calculates the adjustment factor of the preset type through the CVaR method according to the obtained predicted wind speed at the target time, the initial wind power penetration rate, and the confidence of the predicted wind speed; adjusts the constraint range of the corresponding constraint condition according to the adjustment factor; Within the constraint range, simulate the power recovery process for the power recovery scheme corresponding to the wind power penetration rate, and obtain the load recovery amount; adjust the wind power penetration rate, and repeatedly execute to obtain the corresponding power recovery scheme according to the adjusted wind power penetration rate The load restoration amount until the wind power penetration rate is equal to the preset maximum wind power penetration rate; at the target time, select the power restoration plan with the largest load restoration amount to restore power to the power load. In this way, through the adjusted constraint range, the flexibility and speed of power recovery are improved.

Description

Technical field[0001]This application relates to the field of power supply, and in particular to a method and device for power restoration.Background technique[0002]In recent years, with the increasing depletion of fossil energy and the increasing environmental pollution problems, renewable energy represented by wind power has developed rapidly, and the high penetration of new energy sources is becoming one of the basic characteristics of the power system. On the one hand, the large-scale application of new energy sources such as wind power has reduced our dependence on fossil energy to a certain extent and eased environmental pressure; on the other hand, the structure of the power system has become increasingly complex, and high-penetration wind power is due to its inherent randomness and Volatility also makes the system security face greater challenges. Improper handling of local faults is very likely to cause cascading failures, which will lead to blackouts. Therefore, it is nece...
