Hello helper, I'm trying to run this code (energy optimization), but i get an error message :Index in position 1 exceeds array bounds (must not exceed 1).

Hello helper, I'm trying to run this code (energy optimization), but i get an error message .What does "Index in position 1 exceeds array bounds (must not exceed 1)" mean? and how to solve this?

Here is code :

T=24;%time

M = 4;%grid

P=76;%generated power

E=12;%BES energy

K=16;%EV energy

Em=0.3;%BES minimal

Km=0.8;%EV minimal

x=ones(1,T);

y=ones(1,T);

q =ones(1,T);

for n = 2:T

for m =1:M

if abs(E(n,m) - E(n-1,m) <= E)%(6a)

if abs(K(n,m) - K(n-1,m) <= K)%(6b)

if Em(n,m) <= E(n,m) <= E%(6c)

if Km(n,m) <= K(n,m) <= K%(6d)

x(n,m) = P(n,m)+E(n,m)-E(n-1,m)+K(n,m)-K(n-1,m);%(6

y(n,m) = [min(P(n,m)+x(n,m)-E(n)-K(n,m)),0];

q(n,m) = [max(E(n,m)-Em(n,m)+K(n)-Km(n,m)+y(n,m)),0];%

end

end

end

end

end

end

figure()

plot(x,'--*r','Linewidth',2,'MarkerSize',8);hold on

plot(y,'--*g','Linewidth',2,'MarkerSize',8);hold on

plot(q,'--*b','Linewidth',2,'MarkerSize',8);hold on

grid on

hold off

can not fixed it

You use P, E, K, Em and Km as 2-dimensional arrays, but they are only scalar values. Thus all of your if-statements and references to P as an array will throw an error.

Further, "double comparisons" are not possible in MATLAB.

Thus something like

if a <= b <= c

must be written as

if a <= b && b <= c

Thank you!

but stil facing same error

[Torsten]

And where is your revised code ?

[Jem Jem]

stil getting error

I repeat what I wrote before:

You use P, E, K, Em and Km as 2-dimensional arrays, but they are only scalar values. Thus all of your if-statements and references to P as an array will throw an error.

To be precise: E, K, Em, Km and P must be arrays of size (TxM), not scalars of size (1x1).
