1. A display substrate, comprising a display area and an area surrounding the display area, and the display substrate comprises:
a base substrate;
a plurality of pixel units, located on the base substrate and in the display area;
at least one first power line, located on the base substrate and in the area surrounding the display area;
an auxiliary connection structure, surrounding the display area and being in the area surrounding the display area;
a cathode layer, located on a side of the auxiliary connection structure distal from the base substrate; and
a second power line, located on the base substrate and in the area surrounding the display area, wherein the second power line comprises two first portions and a second portion between the two first portions, the second portion surrounds the display area and the second portion is connected to the cathode layer by the auxiliary connection structure;
wherein one end of the at least one first power line is configured for receiving a power signal and an orthographic projection of the other end of the at least one first power line on the base substrate overlaps with an orthographic projection of the auxiliary connection structure on the base substrate, and the other end of the at least one first power line is connected to the cathode layer by the auxiliary connection structure; and
the at least one first power line and the two first portions of the second power line are all in the area surrounding the display area at one side of the display area, and the at least one first power line is between the two first portions of the second power line.
