>>sir
i am getting the load variations by writing the code as below.but i want
that variations for 8hrs,4hrs,10hrs respectively and i want to set the
price at that bus high during peak periods and low during off peak
periods.i read the price sensitive loads but i am not understanding how to
apply.sir if you dont mind please explain me with the code by taking a
small 5 bus system.it is very necessary for my project work.
mpc1 = loadcase('case14o');
>> define_constants;
>> for factor = 0.5
mpc1.bus(3,PD) = factor*41.0;
mpc1.bus(3,QD) = factor*41.0;
results = runpf(mpc1);
mpc2 = loadcase('case14o');
define_constants;
for factor = 0.8
mpc2.bus(3,PD) = factor*41.0;
mpc2.bus(3,QD) = factor*41.0;
results = runpf(mpc2);
mpc3 = loadcase('case14o');
define_constants;
for factor = 1.0
mpc3.bus(3,PD) = factor*41.0;
mpc3.bus(3,QD) = factor*41.0;
results = runpf(mpc3);
end
end
end
is the above code is correct or not please check.
