Key technologies and applications of AC/DC hybrid distributed renewable energy system

In general, distributed renewable energy, energy storage and DC load are connected to the traditional AC distribution network through multistage converters, which leads to low energy efficiency of the system. AC/DC power distribution technology can effectively reduce the intermediate link of AC/DC transformation, and improve the economy, reliability and operation flexibility of power distribution. This paper is aimed at the economic energy problems of efficient access for high-capacity distributed renewable energy and DC load, on the basis of research before, several aspects such as system structure design, key equipment support technology and operation control technology are explored, in order to provide some ideas and references for further research and application of AC/DC hybrid system.
