WECC generic models tunable parameters

asked Oct 14 '1

When you compare tests measurements to simulations using WECC models (i.e. REECA and REPCA models), the parameters you should modify are:

REECB REPCA Tunable Parameters pfflag |vflag |qflag ||refflag ||Local || Plant 0 |0 | 0 || 0 || Kqv || Kp, Ki 0 |0 | 0 || 1 || Kqv || Kp, Ki 0 |0 | 1 || 0 || Kqv,Kvp,Kvi || Kp, Ki 0 |0 | 1 || 1 || Kqv,Kvp,Kvi || Kp, Ki 0 |1 | 0 || 0 || Kqv || Kp, Ki 0 |1 | 0 || 1 || Kqv || Kp, Ki 0 |1 | 1 || 0 || Kqv,Kqp,Kqi,Kvp,Kvi || Kp, Ki 0 |1 | 1 || 1 || Kqv,Kqp,Kqi,Kvp,Kvi || Kp, Ki

Normally, in the studies I have seen only plant parameters are modified. The local parameters are the ones the manufacturer gives or should they be modified too?

If you are simulating a manufacturer-specific inverter, you cannot proceed to tune these parameters without consulting them. Typically, generic dynamic models from inverter manufacturers have these parameters already configured; you may need to update Project-specific settings such as Pmax, Pmin, Qmax, Qmin.
