Sag control technology analysis and parameter design of ship multi-source microgrid inverter
The performance of inverter in ship multi-source microgrid plays a crucial role in power grid operation.Sag control technology distributes power by adjusting its output frequency or voltage.This paper analyzes and studies sag con-trol technology in multi-source microgrid,introduces the basic principle of sag control,and expounds the basic structure of ship multi-source microgrid.The traditional sag coefficient adjustment is generally linear adjustment,and there are problems of overreaction and slow response.An adaptive sag coefficient adjustment method based on particle swarm optimization al-gorithm is proposed,and simulation analysis is carried out.The results show that the adaptive sag coefficient adjustment method can achieve accurate distribution of active power and has high real-time performance.
