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...

description |
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 stabilise a low voltage multi-terminal AC/DC hybrid system. The equivalent model of electric system is studied firstly. Then, an active stabiliser based on Lyapunov theory, and the stabilising feedback law, are proposed. Finally, a study case is built using MATLAB/Simulink, and the feasibility is verified. |
