Introduction

The Solar Enablement Initiative (SEI) demonstrated the technical feasibility of achieving full network visibility from incomplete measurement data using an innovative distribution network state estimation algorithm. This algorithm allows monitoring the voltages, currents and power flows within an entire network and has been demonstrated on 20 medium-voltage distribution feeders. The improved visibility of the network state assists network planners to better evaluate the connection of new photovoltaic (PV) systems and has potential to support additional network assessment, planning and operational processes. During the two past years, this $A2.9 million project has demonstrated that the three participating Australian Distribution Network Service Providers (DNSPs) already have collected enough data to run a Distribution System State Estimation Algorithm (SEA) on the majority of their MV feeders.

Phase 4 of the project commenced in December 2018, focused on –

  • developing the internal version PV analysis tool
  • constraint development and export signalling for real time deployment, and
  • restructuring the backend database and backend performance.
