Multi-infeed AC/DC system dynamic performances and the study of control coordination

The main purpose of this paper is to analyze the dynamic performances and use the fast control actions of the multi converter controllers to improve the performances in the MIAC/DC system. A simple MIAC/DC model is presented is this paper to meet the demand of the study. On the basis of this model, some typical cases are studied. Furthermore, a coordinated control strategy is presented to effectively solve synchronizing problem and damping problem.
