Dear Sir,

You have to clear more for correct answer.

to be more clear, i need a complete data of house electricity usage. for example an excel file which look like this :

lamp 2:00 am 1kw

lamp 2:01am 0kw

refrigerator 2:00am 2kw

.....

have a look to this dataset: http://www.nature.com/articles/sdata20157

Most manufacturers list the power ratings. You can find these either in the user manuals or on the retailer's websites.

Here is a data set for domestic appliances. Only wattage during operation and Idle mode are illustrated.

DSM in smart grid is mainly based on appliances scheduling based on some optimization technique. For this purpose you need only the wattage and length of hours for appliance operation. To prove the effectiveness of your model the supposition of these two parameters is justified.
