**3.3 Load model**

The load model is known as the "load duration curve (LDC)" which is the most favorable one to be used instead of the regular load variation curve. There are some facts about the LDC that should be realized and can be summarized as follows:


d.It is more convenient to deal with than the regular timely load variation curve.

The above discussion for the load duration curve is depicted in **Figure 3** with all pertinent captions related to it.
