Calculations in plotting functions: calc_ac_loading, calc_dc_loading, plot_grid #242

Closed pl0via closed 1 month ago

calc_ac_loading: Instead of taking the absolute sum, the individual directed power flows are offset against each other. As a result, existing power flows are partially omitted. The approach of calc_dc_loadings should be used: calc_ac vs calc_dc

Also, there seem to be calculation steps in reversed order when using calc_ac_loading and calc_dc_loading in combination with plot_grid(line_colors="line_loading").

When calculating the average power utilization, the sum value of all time steps is divided by the nominal power value (s_nom_opt for AC, p_nom_opt for DC), although it should be the rep_snapshots value: average

In order to calculate the share of the optimum power, the average power should be divided by s_nom_opt or p_nom_opt instead of rep_snapshots: plot_grid
