General Connectivity

Connectivity relates to the connections between elements in your grid. Be it distribution lines connecting to transformers, transformers to metres, lines between each other, substations to feeders, etc.. Everything in the grid is connected, however often a utility’s data will say otherwise. This results from years of under-performed documentation and lack of consistency when making changes in the network.

Low connectivity and GIS accuracy make it almost impossible for operators and planners to understand the true energy flow in their grid. This not only makes forecasting complicated, but significantly restricts the effectiveness of DERMS (Distributed Energy Resource Management Systems) and ADMS (Advanced Distribution Management Systems). These advanced systems require a very accurate digital representation of the grid in order to function optimally.

Take an example. An automated DERMS believes that a DER or Electric Vehicle is connected to a certain feeder which is underloaded. As a result, it activates the DER to increase input into the grid and balance the feeder. However, all along the DER was actually connected to a different feeder. Its activation will have no effect on the underloaded feeder, and in fact causes more harm by inputting unwanted energy into a completely separate feeder. All because point of charging was badly associated trough GIS data.

TGI’s powerful algorithms perform a number of tasks:

  • Take existing data and identify what is and isn’t connected
  • Associate and connect disconnected elements to the correct grid elements
  • Validate association values/attributes against real electrical connectivity information
  • Can process CIM, Multi-speak, ESRI and other formats
  • Can work with all GIS systems

Results

After implementing TGI’s algorithm, you can expect a number of key results:

  • Highly improved GIS & topology accuracy
  • Grid-wide element connectivity
  • Digital Twin model and accuracy improvements
  • Optimally functioning DERMS and ADMS systems
  • Accurate energy balancing
  • First step in forecasting
  • Knowledge on asset health
  • Better situational awareness and outage prediction
  • Complete storage of all GIS historical records and updates; operators can scroll back to view any previous versions
