2.1.2. Load profile
Yearly electric load demand profile is one of the necessary steps
to design-planning and optimization of a hybrid system. It is
difficult to find out and also complicated to analyze real load
demand with all minute fluctuations, therefore hourly or daily
averages of load demand is generally used for design-optimization
purpose. But to have a real or nearest to real load variations forall
the seasons is really difficult task, if it fails then system designed
can be oversized or undersized.
