Factors for Load Behavior Analysis
Load behavior affects the performance of the
system. Likewise, the losses also depends on this.
Load profile of any electrical system is deemed not to be absolute,there are what we call the peaks and valleys. Due to the nature of electricity usage, the level of electricity demand varies significantly hour by hour, day by day, week by week , and so on. As a result, load analysis must also varies depending on the seasonality. As an example, suppose an ordinary household uses there lights from 6pm to 11pm, if we try to compare the level of power demand between time 7am and 7pm, a huge electricity demand difference can be observed. This is all because the demand differs from one time to another and it is just wise to know that analyzing load behavior must also be dynamic.

Consequently, due to varying load levels, losses in the system also varies depending on the present level of electricity demand. Losses on electrical components decreases and increases with the square of the line current and are usually at their highest during peak billing demand.Computing for level of losses using the demand can be very difficult if not impossible. Utilities typically considers using the energy in solving such problem.
Our next coming discussions will focus on the factors used in analyzing load profile/behavior of different systems. These factors helps engineers a lot in understanding more the system by applying some assumptions and rules of thumb not only for load analysis but most especially for system's loss analysis and reduction. Some of these factors that we all should be familiar with are as follows; Demand factor, Load factor, Diversity factor, Loss factor, Power factor, etc. All of these strengthens our understanding on the nature and behavior of an electrical system.
