Power utilities could take a host of measures for management of load in the power system at the LT level. Some of these are
- Load curve modification,
- TOD meters,
- Three shift operation and staggered off day. We now explain these techniques, in brief. Load Curve Modification
While a DSM programme is being planned through a power utility, it is significant that the target load curve goals are established beforehand and the electricity demand be managed accordingly.
The following are the most commonly practiced load curve modification goals:
1 Peak clipping
2 Valley filling
3 Strategic conservation
4 Strategic load growth
5 Load shifting
6 Flexible load shape
These terms might be new to many of you. Thus, we should spend some time on explaining their meaning. You might first like to look at the shape of the load curve in each case. We described these load profiles in Figure.
Let us explain what these terms mean.
