Hello

I have a question regarding the load curve for the electricity generation module and cogeneration. In my energy system I have cogeneration plants producing electricity and heat. As they are driven by the heat demand, I have NOT included them in the electricity generation module. My question is: should I have then the load curve of the electricity generation including cogeneration or not?

I get extremely high reserve margins, around 165%, and I think maybe it could be because of that.

Thank you,
Marta

Hi Marta,

The best way to set up cogeneration modules in LEAP is to set them up as a higher transformation module than electricity generation. This way LEAP will run cogeneration plants first to meet the heat demand and then any small electricity requirements can be met by the lower electricity generation module.

Load curves are meant to represent the load shape for the module where it is defined. Remembering that a load curve is a shape of a percent of the load, not the load itself, I think you have set things up correctly.

I can't say why you are getting planning reserve margins that are so high, because there are many reasons this could happen. I suggest that you check to make sure all other results make sense and try to identify the problem that way.

Best,

Tory
