Embodiment Construction
[0074] The present invention will be further described below in conjunction with the specific embodiments.
[0075] Such as figure 1 As shown, a new energy uncertainty power system security risk prevention control method includes the following steps:
[0076] 1) Get future T s The conventional unit power generation plan, load prediction data, new energy plant power generation power prediction data, and N-energy generated n-to-new energy power generation power uncertain variables s The new energy plant station is in force scenario, based on the above data, the future T s Period of N s Safety and stable risks of the scenario;
[0077] 2) In the future T s Period of N s Safety and Stable Scene Mode Mode Performing All Ideal Faults in Function Fault Faults in Function Faults, and the total amount of resection unit and total amount of cutting load after the expected fault; the total amount of the cutting unit and the total amount of cut load are greater than allowed The maximum resecti...
