- Abstract
The mathematical relationship between reactive power consumed by DC system and AC voltage on inverter bus is derived under different control modes, respectively. Based on these relationships, a new definition of multi-infeed short circuit ratio (MISCR) is formulated from the power-flow model of PQ decoupled method. The specific influence of different control modes on voltage stability is analyzed. Considering the relationship between MISCR and voltage stability of AC/DC hybrid system, the characteristics of values of new MISCR are derived. Case study of an actual regional power grid validates these characteristics.
