Hi,
i am working on the power flow of DC microgrid. i am using a behavioral model of power converter, with the code source as follows:
equations
assert(Droop>=0)
if Fault < 0.5
v1 == p1.v - n1.v;
v2 == p2.v - n2.v;
v2 == vref + Droop * i2;
i2 == -(v1*i1)/v2;
else
v1 == p1.v - n1.v;
v2 == p2.v - n2.v;
v2 == 0;
i1 == 0;
end
end
i have a voltage source connected in parallel with other sources, the bus voltage is 350V, the want to limit the power of one source in 1kW. could you please help to solve the problem. i have joined a screenshot of the converter with the voltage source
To begin with, you need to check the source to see how much power it generates, and to this end you can distribute your power according to the connection adopted by the principle that powers add up if currents are in parallel, and voltages are in series.
the source provides the power based on the load demand. i have defined a droop control to ditribute the power accroding to the connection adopted. the droop calcualtion is like this:
Pbat = 0.2;
Pmains = 0.4;
PFuel = 0.4;
Ratio_main = Pmains/(Pbat+Pmains+PFuel);
Ratio_bat = Pbat/(Pbat+Pmains+PFuel);
Ratio_Fuel = PFuel/(Pbat+Pmains+PFuel);
d1 = 0.25/Ratio_main;
d2 = 0.25/Ratio_bat;
d3 = 0.25/Ratio_Fuel;
the fuel power contribution is changing based on the droop percentage. So actually i want to limit the fuel power contribution to 1kw.
