Pilot 1

Polish pilot: City of Bydgoszcz

The pilot covers the major energy nodes of Bydgoszcz, connected to both low voltage (LV) and medium voltage (MV) grids.

Most of the buildings are recent and enjoy some degree of energy self-sufficiency. They have been equipped with smart metres that record energy consumption profiles every 15 minutes and phase voltage profiles every 10 minutes.

Nearly all MV/LV grids at the pilot area’s stations are equipped with balancing metres connected to central Advanced Metering Infrastructure (AMI) system be means of cellular network.10-min voltage and 15-min energy import/export profiles are possible. Detailed network topology is available and modelled using PowerFactory analysis software.

All P, Q, V, I measurements are directly available from a primary substation or indirectly from a SCADA system. This allows for near real-time energy flow tracking management and mapping.

The high-level management architecture proposed for the local energy system is based on the central master application concept, which controls micro energy hubs installed at each energy node or asset. The central application will coordinate the micro energy hubs so that they can act together and provide the following benefits:

  • Local energy management – in terms of loads and generation;
  • Grid flexibility management;
  • Maximum use of locally produced power – reduced energy in-flow from transmission system operators and the high-voltage (HV) grid;
  • Optimised local energy system for ancillary services to the medium-voltage (MV) grid – to avoid congestion of local active grid and to support voltage stability.
