The invention discloses a method for parameter design of a current loop series corrector and belongs to the field of micro-grids. The method mainly comprises the steps that firstly, system parameters required for parameter design are obtained; secondly, a universal current loop mathematic model is established for micro-sources with different control strategies; thirdly, three types of suitable series corrector parameter design schemes are respectively adopted, so that proportion parameters and integral parameters are calculated; fourthly, performance indexes of a frequency domain and a time domain of a current loop control system are analyzed when the three schemes are adopted so that the most suitable design scheme can be obtained; finally, the parameters in the most suitable design scheme are applied to the actual system. The parameters obtained through the method can improve the control performance of a micro-source inverter interface control system and the problems existing in quality and stability of micro-grid electric power and caused by unreasonable parameters of the current loop series corrector are solved.
