General active stabiliser for coordinated control of low voltage multi-terminal AC/DC hybrid system

It is known that if AC/DC converter power exceeds limit it may lead to instability of DC network, especially DC voltage, and further affects the whole system. Concerning the instability risk in coordinated control, this study proposes a stabilisation method allowing large signal stability to stabili...
