Renewable Energy Systems

ATPDesigner supports different algorithms to calculate the steady-state conditions (in ATPDesigner so called Short Circuit Analysis or Load Flow Analysis) of voltages, currents, power, etc., if renewable power plants e.g. wind power plants or a photovoltaic power plants must be considered. ATPDesigner uses current source based models to take into account the behaviour of  wind power plants or photovoltaic power systems which are using DC/AC converter to infeed electrical energy in the power network. These current sources will be controlled by ATPDesigner itself, not by the ATP.

ATPDesigner determines the phasors of the phase-to-ground voltages at the infeed node of the converter analyzing the .LST-file of the ATP and calculates the amount and the phase shift of the current source to achieve the active and reactive power defined by the user.
