I understand that the load got something to do with the appliances connected to generator, but i dont fully understand the concept. Also, if it was about the appliances connected, what will be the Load of a generator connected to the national grid

The load on a generator is measured in Watt hours. Larger generators are expressed as MKWH (megawatthours) this is 1000, 1000 watt hours or 1 million watt hours.
IF a generator is operating by itself, the connected load will determine the load on the generator. If a generator is operating in parallel with another generator they will share the load. The operator has control on how much load the generator will share.
On the national grid, there are many generators connected to the grid. The load centers decide how the load will be shared among the various generators.
Think of it like lifting a box. The weight of the box will determine the load you have to carry. If you're carrying it by yourself, you have to carry the entire load. But you can't carry more than your capability or you'll get hurt. If you get two other people to lift the box with you, the three of you will share the load. But you don't have to share equal load, the stronger might take one end and the weaker guys might carry the other end.
If a generator is not properly sized for the load, the high amperage will burn the windings out. Power companies protect the generators by shedding load.

Loads have....
[1] Inductance load like a choke.
[2] Capacitance load like a capacitor.
[3] Resistance load like a lamp.
[4] Combination load....resistance and inductance and capacitor together....like a motor and transformer.

Huh? Your question is not clear.

The load is equivalent to a single three phase load resistance presented to the generator. This single resistance is made up of thousands of parallel load resistances from homes, factories, etc. If there are multiple generators and multiple regional loads like as when connected to the national grid, the load is shared among all the generators. There are load sharing agreements between each regional generating agency, and load measuring points that keep track of who owes what each month, similar to your own electricity bill. Agencies with power to spare can sell power to other regions that need more power than they can supply on their own.
