How to obtain specific electricity quantity data in the electricity trade between power grids and virtual pools in GCAM?

[shayu-tech]

I'd like to ask everyone: Can I understand "elec gen by gen tech (cogen only)" in this queries as cogeneration? However, I noticed that for example, in the case of the Central Grid region, the sum of "elec gen by region (no CHP)" and "elec gen by gen tech (cogen only)" differs significantly from the data of "elec gen by region (incl CHP)". Which one should I refer to?

Mainly, I want to calculate the amount of electricity input into or output from the virtual pool by each power grid. I found that there are L2232.Production_exports_CHINAelec and L2232.Production_imports_GRID in the GCAM-China model, but I can't output them.

I found the power balance code in GCAM: net.export = generation + cogeneration - ownuse - consumption (Line 261 of L2232.electricity_GRIDR_CHINA.R). I wonder if I can calculate the specific value of electricity trade between the power grid and the virtual pool by solving these four parameters.

Thank you all, and wish everyone a happy life.
