Hi all, I'm doing Dynamic simulation for BESS on IEEE 9 bus system. the problem now that the system is fully depending on the power from the BESS so once it's energy is drained it collapse to instability. So I need to know how to increase the active power from the conv. machine to compensate the BESS and system remain stable. I'm using governor model IEESGO and LCFB1 but still I have Freq. Deviation. Any ideas?
To bring frequency back to 60Hz, you need a AGC model
Test first if model LCFB1 is correctly implemented. Does it update VAR(L) of IEESGO model?
Yes it does I checked V (L+2) in LCFB model and V(L) in IEESGC and both are the same
how to know?, shall I draw this one during the simulation and check?
I plot the VAR (L) and It's a constant value during the simulation, no changes. Dose it mean that the LCFB is not functioning correct? if so how to fix it?
Ok, Fb=0; Tpelec=2; db=0; emax=0.1; Kp=0; Ki=0.005; Imax=0.025; fbf=1; pbf=1
when i changed Fb with positive value I didn't find any change in VAR(L) it remains constant value, however the frequency response improved and reached Zero deviation. the problem that this happened only for couple of Sec. i.e. 20 sec. then system start another freq. deviation.
