Grid Systems#
The following example shows how to utilize the predefined systems. The available systems are listed after the examples.
Example — Using a predefined grid system
from pars.grid_config import get_default_system
config = get_default_system(name='Weak_LV_Grid_LCL_Filter_2L_conv')
The user can also create custom grid systems by combining individual components in examples/grid/pars/grid_parameter_sets.json, under parameter_sets as shown below
Example — Creating a grid system from components
"Weak_LV_Grid_LCL_Filter_2L_conv": {
"description": [
"2-level converter connected to a weak low voltage grid via an LCL filter"
],
"grid": "Weak_LV_Grid",
"filter": "LCL_Filter_fr_1300",
"converter": "2L_LV_Converter"
}
The components are defined in the same file, and predefined components can be found in the components section.
