We are working on a school project where we are simulating the energy system of Cameroon.

We have a problem that our energy balance only shows imports and no local production of either electricity or oil products even though we have defined these processes. The only locally produced energy comes from sources which are consumed in it's primary form e.g. wood.

We have tried to set the shortfall rules for the processes to "requirements remain unmet" but still the import doesn't change.

Does anyone have an idea on how to troubleshoot this? We are quite new to LEAP.

Hi Aleksandra,

One place to look is to double check that you've specified sufficient Base Year Reserves, at the Resources branch, for the input fuels that these processes require. Another place to check, if you are dispatching these processes using the PercentShare rule in the 'Dispatch Rule' variable, is that the 'Process Share' variable is set to something other than zero.

Don't worry - these are commonly raised questions. When debugging, it helps to work your way down the tree structure on the left side, often by displaying different results in Results view, until you find the point at which the problem starts.

Good luck,

Taylor

Excellent question and excellent answer. I actually also have this problem and I have checked using the base year reserves and the Process Share has been set to Merit Order (After defining them).

Basically, there are only imports and no production. I have added some values into the Base Year Reserves (and/or Yield), but only some of them show up in the Energy Balance.

Any ideas?

Sean

Hi Sean,

There are a few other things that you can try, if the first few suggestions don't cut it. The simplest checks are that you have defined sufficient capacity - this can mean ensuring that your units and scaling factors are set correctly in your electricity generation module. Sometimes what can appear to be a 'zero' is actually just a very small number, due to incorrect scaling.

Another place to check is that you've defined a non-zero load curve for your electricity module (providing you've selected a 'Load shape for entire system', under Basic Parameters: Loads). Load curves are given as yearly shapes, which you can define under General: Yearly Shapes. You can read about this here:

Hope this helps,

Taylor
