基于轨迹灵敏度分析的直流调制参数优化设计
Parameter Optimization Design of DC Modulation Based on Trajectory Sensitivity Analysis
摘要
Abstract
A method for parameter-optimization of DC-modulation controller on the basis of time domain simulation has been proposed in this paper. In this method, the parameter optimization problem of DC-modulation controller is converted to the non-linear optimization problem with parameter constraint, and then the constrained optimization problem has been converted to the unconstrained optimization problem. The gradient information of objective function is obtained by means of the simulation of trajectory sensitivity, and then the parameters of DC-modulation controller are optimized by Quasi-Newton Algorithm (DFP). Because the objective function reflects the power oscillation behavior of AC/DC interconnected power systems, the proposed method can be used to effectively damp the power oscillations of AC/DC system incurred by severe disturbances. The eigenvalue analysis and time domain simulations on the IEEE 4-generator AC/DC system verify the effectiveness and robustness of the proposed method.关键词
