| titleOfInvention | Order-reducing variable selection method for order reduction of power electronic interface grid-connected system model |
| abstract | A method for selecting a reduced variable of a power electronic interface grid-connected system model reduced order can improve the adverse effect that the reduced order processing is carried out on different state variables aiming at different model reduced order errors in the current application; the method comprises the following steps of 1, establishing an electromagnetic transient model of a power electronic interface grid-connected system; 2. obtaining a characteristic value of the system at a steady-state operating point, and introducing a characteristic value sensitivity method to analyze the correlation between the characteristic value and each state variable of the system; 3. extracting singular perturbation parameters corresponding to each state variable of the system, and establishing a singular perturbation model of the system; 4. and according to a given model order reduction error range, obtaining a leading influence state variable of the leading characteristic value by applying different leading characteristic value selection modes, and performing order reduction processing on the rest state variables. The invention can select different state variables to carry out order reduction treatment according to the requirement of the order reduction error of the model, and fully considers the practicability and effectiveness of the order reduction variable selection method. |
