optimization of energy management system _problem objective error

Hi,

i am getting error for below code of optimisation objective:

An error occurred while running the simulation and the simulation was terminated

Caused by:

• Objective must be a scalar OptimizationExpression or a struct containing a scalar OptimizationExpression.Please help

prob.Objective =dt*Price'*PbattupsV +dt*Price'*PbattdchV*Nb_dch1V'+ dt*Price'*PbattchV*Nb_ch1V' ;

Hi NN,

I understand the error message you're encountering indicates that the expression assigned to prob.Objective is not being recognized as a scalar OptimizationExpression or a struct containing a scalar OptimizationExpression.

The objective function in optimization problems should result in a single scalar value that the solver attempts to minimize or maximize. When you're setting up an optimization problem in MATLAB, it's essential to ensure that the objective function conforms to this expectation.

Your objective function seems to be trying to compute a cost or value by multiplying time intervals (dt), prices (Price), and battery power variables (PbattupsV, PbattdchV, PbattchV) adjusted by efficiency (Nb_dch1V, Nb_ch1V).

However, without seeing the complete context or definitions of these variables, a potential issues can be identified:

Dimensionality: Ensure that the final result of the objective function is indeed a scalar. This means the matrix or vector operations inside must ultimately condense down to a single value. Use functions like sum if necessary to aggregate results.

I hope it helps!
