Multi Level Integrated Energy Management and Control Method for AC / DC Hybrid Flexible Substation Area Based on Power Internet of Things

With the increase of DC source loads such as photovoltaic power generation and electric vehicles, AC/DC hybrid distribution network technology has developed rapidly. In order to improve the regional energy management capabilities, a control method for integrated energy in AC/DC hybrid flexible stations is proposed. Based on the basic structure of traditional power internet of things (PIoT), combined with the characteristics of multiple energy sources in AC/DC flexible stations, the overall architecture of multi-level energy in AC/DC flexible stations is proposed, and the top-level architecture of "Cloud, Tube, Edge and End" is optimized. On this basis, according to the system operation mode and functional requirements, a multi-level operation control method for AC/DC flexible station area is proposed to meet the requirements of distributed energy access and diversified load control.
