An Overview of Morphological Development and Operation Control Technology of Power Electronics Dominated Distribution Area

With the development of new infrastructure, renewable energy and the increasing demand of DC load, distribution area presents the development trend of power electronics domination. It brings new challenges to the morphological development and operation control of distribution area. This paper summarizes the domestic and international developments, technical characteristics and application scenarios of power electronics dominated distribution area from six aspects including structural morphology, low voltage interconnection morphology, optimal dispatch, power quality management, stability analysis and control, as well as fast protection of fault. Finally, the future key research directions are prospected.
