I want to know what happen to my solar PV model in PSS/E. When I evaluate the power flow in *.raw data, the voltage of POM is 1.0 pu. However, In dynamic simulation, It changes 0.95 pu in next time step.

My code is..

psspy.fnsl([0,0,0,1,1,0,0,0]) psspy.cong(0) psspy.conl(0,1,1,[0,0],[ 100.0,0.0,0.0, 100.0]) psspy.conl(0,1,2,[0,0],[ 100.0,0.0,0.0, 100.0]) psspy.conl(0,1,3,[0,0],[ 100.0,0.0,0.0, 100.0]) psspy.fact() psspy.ordr(0) psspy.tysl(0)

open dynamic file and setting Monitoring channel then, Check the initialize ok. psspy.run(0, 10.0,1,1,0) when 10 seconds, I change the set of PF reference.

However, the result shows the voltage of POM is 1.0pu at 0 seconds Then, it changes to 0.95 pu at next step (0.0083s)

what is the problem?

psspy.fact()
psspy.ordr(0)

psspy.tysl(0)

psspy.run(0, 10.0,1,1,0) 10.0,1,1,0)
