Hello
I am trying to write a code using the PSO algorithm to optimize the PV and battery system. So I was looking for an example code and there was one in Mathworks. But there is an optimization problem in it with PSO code. How can I write an optimization problem and PSO code separately? Please help me
Example code part of PSO:
for i=1:NPOP
cc=1;%a value for cost
ww=0.3;% a value for lose of load probability%
kkk=2;%renewable energy factor%
ff=0;
%C=0.9;%price of electricity
%K=0.99;%renewable energy factor%
while ww>=W | kkk>=K% LOLP/REfactor
particle(i).position(1,:)=unifrnd(0,45,1,nvars);%pv kW
particle(i).position(2,:)=unifrnd(0,8,1,nvars);%autonomy days
particle(i).position(3,:)=unifrnd(1,20,1,nvars);%number of houses
particle(i).position(4,:)=unifrnd(0,10,1,nvars);%number of wind turbine
for g=1:4
particle(i).velocity(g,:)=rand(1,nvars);
end
%----convert------------
p_npv=particle(i).position(1);
houses=round(particle(i).position(3));
nwt=round(particle(i).position(4));
%-----------------------
ff=ff+1;
ww(i)=LPSP;
kkk(i)=renewable_factor;
end
