Hi 

I am working on a project in the field of Power System Engineering, wherein am trying to optimize the generation schedule on board a ship by including a battery storage system for better efficiency.

when am trying to execute the program (YALMIP_MATLAB interface) it is taking a very long time to execute (more than 6-7 hrs and I have to interrupt the progress)

Am attaching the screenshot of interface

if required I will share the code as well, please may I know where am going wrong?

  Hi,

  Could you please share a model file generated by the gurobi_write function and a LOG file of the run with a TimeLimit of let's say 1800 seconds?

  Best regards,
  Jaromił

  Hi Manikanta,

  Please use the gurobi_write() function, see the respective documentation. You could call this function directly before or after optimizing your model. An example of this application can be found in the mip1.m example.

  Best regards,
  Jaromił
