The SSID option is stored within a anonymous "wifi-iface" section. Since
you cannot address those sections directly, you have to use the
foreach() iterator to loop over them:

  local new_ssid = "my_ssid"

  -- loop over sections of the type "wifi-iface" in config "wireless"
  uci:foreach("wireless", "wifi-iface",

    -- the iterator callback, receives a section table as only argument
    function(s)

      -- the ".name" attribute in the "s" table holds the uci section id
      -- needed to address options within the section, use it to set the
      -- new ssid
      uci:set("wireless", s[".name"], "ssid", new_ssid)

      -- returning false here aborts the iteration, ommit this if you
      -- want to re-invoke this function for further wifi-iface sections
      return false
    end
  )

  -- save & commit
  uci:save("wireless")
  uci:commit("wireless")
