In the shuls I've davened in (American, Ashkenazi), we always stand during Psalm 29 during Kabbalat Shabbat. Why do we do this? What makes it different from the other psalms?
The beginning of an answer...I will try and locate some sources.
It says on the OU site here:
After we recite the five consecutive psalms that correspond to the first five days of the week, we rise from our seats and recite Psalm 29 which corresponds to the sixth day, Erev Shabbat. We stand up in honor and in awe of the presence of G-d that we experience in recognition that Shabbat the Messianic Day of Eternity has arrived. We sing joyously Havu Lashem Bnei Eilim…. – You the children of our Patriarchs, Give unto G-d, Give unto Him your honor and strength, and bow down in this holy space.
I saw similarly that Mizmor LeDovid corresponds to erev shabbos here which attributes the idea to Sichas Kodesh 2 p. 121
