Hello MATPOWER users!
can you please suggest me how to modify the following in matpower code.
I have 4 bus system. 'case4'
now bus 1 is slack bus and rest busses are PQ load bus.
Now I want to modify the bus 4 as PQV bus where apart from PQ voltage to at
this bus is known now. additionally, I want to maintain this bus4 voltage
supplying reactive power from bus 2, the augmented equation is now ∆V=[V2
V3]' and ∆Q=[Q3 Q4]'. the equation relating the changes in power to the
changes in the voltage magnitudes and phase angles for the Newton-Raphson
method by augmenting the jacobian becomes, [ΔP2 ΔP3 ΔP4 ΔQ3 ΔQ4]'= [P2/δ2
P2/δ3 P2/δ4 P2/V2 P2/V3; P3/δ2 P3/δ3 P3/δ4 P3/V2 P3/V3; P4/δ2 P4/δ3 P4/δ4
P4/V3 P4/V3; Q3/δ2 Q3/δ3 Q3/δ4 Q3/V2 Q3/V3 Q4/δ2 Q4/δ3 Q4/δ4 Q4/V2 Q4/V3]=
[Δδ2 Δδ3 Δδ4 ΔV2 ΔV3]'.
How can I augment the above equation in MATPOWER so that the load flow
results obtained must have this concept. can anyone provide me a simple
coded solution based on any bus system available in manpower
