Open-Source Distribution System Load Flow
Challenge and objective
- Robust methods are needed for decision support in distribution systems.
- The tools must be able to handle flexible sources as generation, loads, storages as well as different topologies from the perspective of loss minimization and self-healing concepts.
- Tools should be open-source and sufficient general to be used as building blocks in more specialized concepts
Work performed
- A distribution system load flow is developed in Python.
- It has the classical Forward-Backward-Sweep as a core but is flexible in terms of system topologies (radial operation) and provides a number of sensitivities for impact of changing active and reactive loads at individual buses.
- Calculates an optimal voltage profile where both active and reactive power may be decision variables
Significant results
- A toolbox developed which can be used by researchers in CINELDI and students as a building block for more tailor-made concepts.
- Open-source available on Github.
- Currently used by researchers for studying flexibility
Impact for distribution system innovation
- The tool gives the option to quickly prototype and test special concepts.
- A kernel for more advanced coordination and optimization concepts.
