Solutions

For utilities

Study transmission and distribution networks: from the daily load flow to contingencies, reliability indices and the connection of new generation.

What you can do with PowerGridTools

Import existing models from PSS/E, CGMES or PowerFactory DGS instead of redrawing them.
Screen N-1 and N-2 contingencies and cascading outages, and compute SAIFI and SAIDI of feeders.
Assess how much new generation each bus can host, and reconfigure feeders for lower losses.

AC load flow

Balanced load flow with the Newton-Raphson, Gauss-Seidel or Z-bus Gauss-Seidel method.
Time-series load flow

Quasi-static load flows over load and generation profiles.
State estimation

Weighted-least-squares estimation of the network state from measurements.
Short circuit to IEC 60909

Initial, peak and breaking currents with the correction factors of the standard, for maximum and minimum currents.

IEC 60909-0
Contingency analysis

N-1 outages and N-2 branch pairs with overload and voltage violations.
Distribution reliability

SAIFI and SAIDI of feeders, and supply-point reliability by minimal cut sets.
Feeder reconfiguration

Switch positions for minimum losses.
Hosting capacity

How much new generation each bus can take within limits.
