How can I solve the problems with implementation of Direct power control for DFIG ?

I've implemented DPC for DFIG in matlab/simulink. In that, active power (Pref=0.9pu) be well controlled but the reactive power (Qref=0) instead of remain at zero, it is fixed at -1?!! Please let...

How can I implement Direct Power Control (DPC) for a DFIG-Based Wind Turbine?

I've implemented DPC for DFIG in matlab/simulink (parametrs of DFIG in 'pu'), according to some new IEEE journal papers. I've compared real power Ps=(3/2)*Re{Vs.Is*} and reactive power is...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.
