The present application relates to power industry safety domain boundary fitting technology, in particular to a kind of high-dimensional static security domain boundary fitting method of power system, considering system generator output constraint, node load value sampling is carried out, through power flow calculation, the sample in the security domain is filtered out, and initial sample set is formed.Boundary sample search algorithm is proposed, for each sample in initial sample set, find a sample in the security domain, a sample outside the security domain, and satisfy the distance between the two is less than the set distance threshold value.The data in the boundary sample set in the original power injection space is converted to new three-dimensional feature space by deep neural network model.Extract the boundary in feature space by the weighted tilt decision tree algorithm based on information gain ratio, and evaluate the boundary performance, select the optimal boundary.The method can realize the fitting of high-dimensional boundary of power system security domain, and reduce the error with actual boundary.

The invention belongs to the field of ground maintenance of a generator controller of an aviation power system, and particularly relates to a design method for testing a hardware control script, which comprises the following steps of: pre-defining a test case format at the front end of an Excel test case through a standard Excel file; a first AST tree is generated after analysis, test actions are set for Excel testing, and different test actions are defined; the DSL test script front end receives a plain text format file as input, analyzes the plain text format file and outputs a second AST tree; setting different statements in the DSL test script for definition; and generating an operation based on each tree node of the first AST tree and the second AST tree, and automatically controlling the test hardware. A user can use the Excel type test case or the test script DSL to design the test script, so that the test case can be ensured to be clear and readable, and the test script DSL can be directly used to compile the test case with special requirements when necessary, so as to provide enough degree of freedom.

The invention provides a large-scale unit commitment solving method based on first-order optimization and successive fixation, and relates to the field of data processing. In the method, through instance perception preprocessing scaling, normalization is carried out on related parameters of a power system generator set, a linear relaxation model is generated and input into a first-order linear programming solver, and a continuous domain solution vector is obtained through iterative updating. And calculating confidence and logic consistency of binary start-stop, start-stop and shutdown variables based on the solution vector, and outputting a weighted confidence rule set for successive fixation. And if the conditions are met, solidifying the variables, updating the linear relaxation model, and inputting into a solver to obtain a new solution. After multiple rounds of successive fixation are executed, if the number of the fixed binary variables exceeds a threshold value, a small-scale mixed integer linear model is constructed, accurate solving is conducted through a branch shear method, and finally an executable generator set combination plan is output. By implementing the technical scheme provided by the invention, the solving efficiency of the server in processing the SCUC problem can be improved.
