This video shows the functionality of the Load Flow module which performs studies for 3-, 2- and 1-phase AC and DC systems for meshed, looped and radial networks from HV to LV. It includes disperse generation models such as wind power, hotovoltaic, small hydro, geothermic, etc. and provides a wide variety of calculation options to address specific applications. Modelling can be particularly defined with NEPLAN® C/C++ API.
