1results about How to "Make up for instability" patented technology

The application provides a state space-based multi-line DC power flow controller modeling and control parameter optimization method, the instability of the DC network ring network system caused by the addition of the DC power flow control is made up by adding the matrix E containing PI control, and the influence of the phase margin and the dynamic characteristic is considered, the game optimization of the control parameters in the dynamic time domain model is carried out based on the eigenvalue, and the application has high universality and strong portability, and has high guiding significance for improving the control performance and optimization ability of the line-to-line power flow controller. The application models the multi-line DC power flow controller, breaks through the barrier of the scale expansion of the DC power flow controller, has the advantages of simple structure, high universality, strong applicability and the like, and provides a model basis for the subsequent research of the DC power flow controller.
