Problems solved by technology

[0006] (1) The evaluation standard of user energy consumption is not uniform, and the result of horizontal comparison is not so accurate to a large extent if the user energy consumption evaluation is not uniform
[0007] (2) The evaluation method of user energy consumption is relatively simple, and a reasonable evaluation method is one of the keys to evaluate the system, and the single method of determining the weight is easily affected by the characteristics of the weight method itself, which makes the evaluation result greatly affected. deviation
