Hi,

Do you have any idea how to mdel the relay DRS50 for interconnexion ?

Thanks in advance,

do you have an example of Outage Statistics Data File adapted for PSSE ? how to create it?

Hi,

I dont know if someone in this forum is familiarised with using the reliability analysis in PSSE. I want try this for the first time, what is the input that i must enter in the software? and how i run the simulation?

Best regards,

When you say dynamic limit in the model do no match the LF, What do you mean exactly? What i must check and change??

How we can deal with this problems of initialisation?

SEXS AT BUS 84580 MACHINE 1 INITIALIZED OUT OF LIMITS
IEEEG1 AT BUS 81213 MACHINE 1 : INITIALIZED OUT OF LIMITS
CONTROL WT3E1 AT BUS 84620 MACHINE 1 WRONG INITILIZATION:¡¤? 1.1000

I read a lot of comment about this issue and i can confirm that the load flow is perfect but i d'ont know why i face an increase (until 30kV in some busbar) of voltage when i convert the machines.

Thank you in advance,

I face the same problem for IEEEG1, Can you help please

@EBC how OPF provide the optimal size and location for compensation? there is a special code for this?

if you want to reduce or increase loads, you can choose in transfer dispatch methods DFAX loads instead of DFAX generation

i always follow u jconto, i found your comments really effective, can we keep in touch. My mail is yahya.mrabti@gmail.com

But the PV analysis is a transfer of generation between the source area and the sink area, so if there is no generation in the sink one, how he will dispatch the generation in this area? the is no plant to reduce

plz can u check your mon file, are you sure of your sub file contain generation unit ?

can you share with us this python script ?

but he show me all the buses and not only the buses in 'ZONE_ETUDE'!! how i can solve that problem? and also in column generator dispatch i see generator different form the area that i selected in 'ZONE_ETUDE'

this is my mon file MONITOR TIES FROM SUBSYSTEM 'ZONE_ETUDE' MONITOR VOLTAGE RANGE KV 400 0.937 1.087 MONITOR VOLTAGE RANGE KV 225 0.910 1.087 MONITOR VOLTAGE RANGE KV 150 0.90 1.10 MONITOR VOLTAGE RANGE KV 60 0.90 1.10

Dear friend, i run pvf analysis as explained by the most of expert in this platform, i got a good result but i face a big problem, all contingincies are ine the zone that i selected in the sink area but i dont understand why in the bus voltage column the excell file show only buses in 60kV

In the toolbar you will find an icone "export to Excel" and you will find 3 choices, choose QV curve.

can you check if there is generation in your sub file? because it seems that there is no plant which participate in the dispatshing

thank you, can we say that the output pf PTDF is the sameas the activity TLTG inPSSE

can you be generous and explain the meaning of PTDF and OTDF? what is their purpose.

plz can u help me to that. the method is very well and sound really logic. but in practice i found many difficulties
