Feasible parameters domain optimization design method for grid-connected inverter under transient stability constraints
摘要
Abstract
Aiming at the stability problems caused by improper design of the phase-locked loop as well as current loop parameters of a grid-connected inverter under weak grid,a feasible domain optimization design method for control parameters that takes transient stability constraints of grid-connected inverter into account was proposed.Firstly,the feasible domains of the parameters of the phase-locked loop and current loop were obtained by the D-partition method under the constraints of amplitude margin,phase margin and bandwidth.Then,the feasible parameters domains were further optimized by the transient stability constraints of the fast and slow subsystems in singular perturbation model of grid-connected inverter.Finally,based on the designed control parameters,a validation was carried out by SpaceR hardware-in-the-loop experimental platform,and the results show that the parameters designed by this method can guarantee the control performance and transient stability of the grid-connected inverter at the same time.关键词
