Feasibility check of topology changes in radial distribution networks
Challenge and objective
- In radial distribution grids the removal of overloads and voltage problems will in general either reduce the active load, increase the reactive support or change the topology.
- In 2019, the development of PyDSAL (a tool for distribution system load flow) was reported in CINELDI. A core element of this tool was a module for identifying topologies of sub-systems where a load flow was conducted afterwards.
Work performed
- The tools was further developed and the topology search algorithms generalized in a specialization project, a MSC-thesis and a summer job funded by CINELDI.
- The topology module got the ability to build up a sub-system from any feed-in node and then solve the load flow.
Significant results
- For a radially operated distribution system, the load flow can be conducted for any alternative feed in.
- Any line may be disconnected, and load flow conducted for sub-systems and alternative feed-ins.
- Testing is done for different topologies.
Impact for distribution system innovation
- The topology module and the load flow tool may be integrated in tools where it is a need for checking alternative topologies and the impact of changes.
