Hi all,
I am working on an economic dispatch and unit commitment problem with plug-in electric vehicles (PEVs) integrated to a power system. I plan to test my model using the IEEE 24 bus RTS system. My issue is that the number PEVs I have in my model are simply not enough to cause any substantial effect on the original bus loads and generating set capacities used in the original test system which has an annual peak load of 2850 MW. In contrast, a typical PEV has load of about 70kwh which will make a total of 1000 vehicles still insignificant in a system with load of 2850MW.
Can I adjust the bus loads and generators capacity to something much lower so that the effect of including the EVs at buses in the test system can be more significant?
I see in several papers the authors referring to the IEEE bus systems in their studies as being modified. I just want to be sure I can modify the bus loads and generation capacities without tarnishing the integrity of the system.
NOTE: I am not modifying the nodal connections given in the IEEE 24 bus system. Just the loads and generator capacities.
Thanks
can't you increase the number of your PEVs? scale up?
what is the scope of your work. are you doing economic optimization? or resilience testing (for cyber threats)?
the simple answer is, yes you can change your system data. if you're reducing loads, transmission losses will reduce. if you're only doing OPF, not UC, and all generators are switched on, then reducing loads too much will make the problem infeasible because some generators have a P_min rating. you'll need to switch off some generators. to choose which ones, you'll need to solve a UC problem, not just an OPF.
Baraa Mohandes Thank you for your answer. Yes, I went ahead and increased the number of PEVs to check for the effect that different penetration levels of PEV had on the system.
Thanks
You're welcome.
I have a paper where i analyzed a cyber-threat scenario with the IEEE24RTS system and a large swarm of PEVs. check it out, I hope it helps

from where can i get the load flow analysis of IEEE RTS for a 24-bus or 72 bus, i.e., one area or 3 area system
