ČEZ Simulation test

ČEZ Company (ČEZ) launched WPP AMM (Wide Pilot Project) with 35.000 meters in the distribution field. Output from this pilot project brought some essential facts about the future of Smart Metering roll-out.

Even this pilot project was one of the largest smart metering pilot projects in the Central Europe, professionals from ČEZ as well as from supplier´s side, requested more detailed view and opinion about the influence of the roll-out to the current distribution grid, IT systems, and others. On the basis of this requirement NESS Czech with partners Mycroft Mind and CERIT high computing center (located in Masaryk University in Brno) proposed the unique simulation and performance test, which shall bring the answers to questions, ČEZ and others may have.

Requirements on the simulations in the framework of WPP AMM:

  • Build up the hypothetical topology and behavior of the network with higher number of PoD´s (Point of Delivery)
    • Simulation of 100.000 PoD´s
    • Simulation of 3.500.000 PoD´s, which represents the total PoD´s in the distribution network, which ČEZ currently operates on the low voltage level
  • Put the IT infrastructure for the centralized data control and collection system in the configuration for 3.500.000 PoD´s into operation
  • Simulate the operation of 100.000 and 3.500.000 PoD´s collect and evaluate the gained data.
  • Use for the simulation and performance test the same data collection systems as are implemented within WPP AMM
  • Collect the data about the workload of IT infrastructure and particular components of the system to identify bottlenecks

Detail of the simulated environments – what was simulated


Distribution substation

  • Quality of the communication lines to the data control and collection system
  • Speed of communication
  • Reliability of the connection

Point of delivery (meter)

  • Quality of the communication lines to the distribution substation
  • Reliability of the connection
  • Two types of PoD´s (one tariff /two tariff s)

Topology of the grid

  • Number of the distribution substations
  • Realistic quotient of the PoD´s to distribution substation

2. MONITORING of SW & HW components in the system

  • HW components under the workload
    • CPU, disks, I/O operations, network communication, …
  • SW components
    • Application´s utilization rate, responses, troubles, …
