Abstract

Flexible multi-state switch is the key technology to solve challenges of the current distribution network

such as the diversification of electricity demands

the large-scale access of distributed power

the complexity of power flow coordination control and so on. Firstly

the research architecture of flexible multi-state switch technology is introduced. Then

in terms of technical contents

research progress and existing problems

the key technical problems in the research and demonstration of flexible multi-state switch are introduced

including topology selection and parameter optimization

access mode

optimal regulation

device development

test

integrated demonstration and so on. Finally

the problems and challenges of flexible multi-state switch are analyzed from three aspects

such as topology selection

device manufacturin

g and operation control. It is pointed out that small size

low cost and high efficiency are the development direction of flexible multi-state switch devices.
