2. The method according to claim 1 , wherein the adjusting an initial upper limit value corresponding to the storage device according to comparison of a target power consumption with a current power consumption of the storage device at a current power consumption level, so as to obtain an adjusted target upper limit value comprises:

calculating a difference between the current power consumption and the target power consumption; and

adjusting, according to the difference, the initial upper limit value to obtain the adjusted target upper limit value.

3. The method according to claim 2 , wherein the adjusting, according to the difference, the initial upper limit value to obtain the adjusted target upper limit value comprises:

acquiring, in a case that the difference is greater than a preset difference, an adjustment ratio corresponding to the storage device; and

adjusting, according to the adjustment ratio and the difference, the initial upper limit value to obtain the adjusted target upper limit value.

4. The method according to claim 3 , further comprising:

acquiring, in a case that differences within a preset number of times are all less than or equal to the preset difference, an integration constant according to the preset number of times; and

adjusting, according to the integration constant and a sum of the differences, the initial upper limit value to obtain the adjusted target upper limit value.

5. The method according to claim 4 , wherein the acquiring, in a case that differences within a preset number of times are all less than or equal to the preset difference, an integration constant according to the preset number of times comprises:

determining, in a case that the differences within the preset number of times are all less than or equal to the preset difference, that there is a static error between the current power consumption and the target power consumption.

6. The method according to claim 1 , before adjusting an initial upper limit value corresponding to the storage device according to comparison of a target power consumption with a current power consumption of the storage device at a current power consumption level, the method further comprises:

querying, according to the current power consumption level, rated power consumption corresponding to the current power consumption level;

acquiring a safety difference corresponding to the current power consumption level; and

subtracting the safety difference from the rated power consumption to calculate the target power consumption of the storage device at the current power consumption level.

7. The method according to claim 6 , wherein the querying, according to the current power consumption level, rated power consumption corresponding to the current power consumption level comprises:

judging, according to a preset power consumption level range, whether the current power consumption level is valid; and
