Abstract

The invention discloses a method and device for analyzing interaction between power electronic power supplies. The method comprises the steps of calculating the self-impedance gi,i and mutual impedance gi,j of power electronic power supply stations in a high-proportion power electronic power system, and generating an interaction degree matrix Gm(jomega) between the power electronic power supply stations based on the self-impedance gi,i and the mutual impedance gi,j, based on the interaction degree matrix Gm(jomega) between the power electronic power stations, calculating a relative gain matrix RRGA between the power electronic power stations, and based on the relative gain matrix RRGA between the power electronic power supply stations, determining the interaction degree between the power electronic power supply stations.

Description

Technical field [0001] The present invention relates to the field of power system modeling techniques, and more particularly to methods and systems for interaction between power electronics. Background technique [0002] The installed capacity of my country's new energy unit is increasing year by year, and the proportion of power electronics represented by new energy power supply is increasing in power systems. In recent years, there is an occurrence of a high proportion of new energy power systems between the main incentives between power electronics and power. [0003] Domestic and foreign scholars have carried out a lot of research on complex interaction between power electronics source station. However, most existing research on artificial intelligence algorithm or correlation analysis between measurement station relations, said method requires a large calculation amount, the lack of theoretical calculation process, and most algorithms have poor generalization performance, ro...
