Diagram of integrated duration curve used in system operation:
Integrated duration curve is obtained from load duration curve. It is drawn in between load on Y-axis in KW/MW and the X-axis represents the units generated (KWH/MWH).
Importance of integrated duration curve: Following information is obtained from integrated duration curve: It gives the total number of units (KWH/MWH) generated for the given demand in (KW/MW).
The number of units consumed by a load up to a particular time of a day can also be shown on a curve which is called as mass curve.
