How can I write an optimization problem and PSO code separately?

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

%W=0.2;%lose of load probability%

%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);

ad=particle(i).position(2);

houses=round(particle(i).position(3));

nwt=round(particle(i).position(4));

%-----------------------

[LPSP,price_electricity,renewable_factor,b,ali]=techno_economic_analysis_pso(houses,p_npv,ad,nwt);

ff=ff+1;

ww(i)=LPSP;

kkk(i)=renewable_factor;

end

Example code:
