Simulation of Renewable Energy Sources Using PowerFactory

[Support]

Complex studies for the integration of renewable generation into electrical networks are an integral part of network planning and analysis. PowerFactory combines extensive modelling capabilities with advanced solution algorithms.
Network and park models are easily created using an intuitive drawing toolbox, while the use of model templates and an extensive model library allow complete plant models to be constructed efficiently.
A full set of tools is provided to undertake the wide range of studies required for grid connection and grid impact analysis of wind parks, PV generation and all other renewable energy power plants. Recurring tasks can easily be automated using scripting tools, to streamline the analysis process.

[Support]

For grid integration or grid impact studies of PV systems you need modules such as load flow calculation, short-circuit calculation, power quality, power system stability, etc.
These modules are selected by client with the Base Package. Depending on type of study required and the details of analysis, then modules can be selected or added at later stage to the license.
