2results about How to "Quick and effective identification" patented technology

The application discloses a secondary frequency control method and device resisting false data injection and a storage medium, belongs to the technical field of micro-grid control, and is used for performing secondary frequency control on a target distributed power generation unit in a distributed micro-grid. The method comprises the following steps: acquiring local frequency compensation amounts of each distributed power generation unit; inputting the local frequency compensation amounts of the remaining distributed power generation units into a pre-trained neural network, and outputting a predicted frequency compensation amount of the target distributed power generation unit; detecting whether false data injection occurs according to the local and predicted frequency compensation amounts of the target distributed power generation unit; and when it is detected that false data injection occurs, replacing the local frequency compensation amount of the target distributed power generation unit with the predicted frequency compensation amount of the target distributed power generation unit, and compensating for a frequency deviation caused by droop control of the target distributed power generation unit. The application can solve the problem that false data injection destroys the secondary frequency control function.

This invention relates to the field of computer graphics technology, and more particularly to a method, system, device, and medium for verifying 3D models. The 3D model verification method includes the following steps: Step S1: Receive the user's detection command in real time and obtain the 3D model to be verified; Step S2: Analyze the 3D model to be verified and obtain geometric feature information and material feature information; Step S3: Match the geometric feature information and material feature information with the geometric feature information and material feature information of existing 3D models in the system's database one by one to determine whether they are consistent. If they are consistent, the first operation is performed; if they are inconsistent, the second operation is performed. This invention is aimed at 3D models with materials in the design industry, and achieves rapid storage and management of 3D models through a precise and effective verification method.
