船舶直流微电网的分层控制

Hierarchical Control of Direct Current Microgrid on Ship

随着新能源技术和电力电子技术的不断发展,新能源在船舶上的应用,受到了越来越多的关注。而直流(direct current,DC)微电网在船舶上的应用,是新能源更有效率地接入船舶电力系统的关键技术之一。旨在介绍针对直流微电网中电压、功率的不稳定、不平衡导致的电能质量问题,以及目前对该类问题的分层控制方法,并对控制方法进行分析和比较,总结出未来分层控制的发展方向。

With the continuous development of new energy technology and power electronics technology,the application of new energy on ships has received more and more attention.The application ofdirect current(DC)microgrid on ships is one of the key technologies for new energy that can more efficiently connect to the ships’power systems.The purpose of this study was to present the power quality problems caused by the instability and imbalance of voltage and power in the DC microgrid,as well as the current layered control methods for such problems,to analyze and compare the control methods,and to summarize the future development direction of layered control.
