Distributed Generation

Power system phenomena such as reverse power flows, voltage dips and swells, varying fault levels and equipment loading are some of the major challenges associated with distributed generation in electricity systems.

Of particular note are the challenges arising from the interaction between highly volatile generation from renewable sources and an increasing variability in consumption.
The extensive model library in PowerFactory offers users the possibility to use ready-made load flow and dynamic models for generators and converters, PV systems with integrated power calculation based on solar radiation, fuel cells, wind generators and battery storage (according to IEC and WECC).

To account for the interaction between consumption and generation in the network, models for single and three-phase loads, consumption energy profiles and models for electric vehicles can be used.

This provides the perfect basis for all the necessary analysis, from unbalanced network assessments and voltage drop/rise calculations, to Quasi-Dynamic Simulations and Voltage Profile Optimisation. Using the Hosting Capacity calculation, the remaining capacity for renewable energies can be evaluated, while Probabilistic Analysis and Reliability Analysis can be performed in order to determine the risks of uncertainty.
