Grid-Focused System Models

Transformer-Grid-focused tessif system model example.

tessif_examples.scientific.grid_focused.create_lossless_commitment_msc(periods=24)[source]

Create the TransCnE system model scenarios combinations.

Created by Tim Hanke. Modified by Mathias Ammon.

Parameters

periods (int, default=24) – Number of time steps of the evaluated timeframe (one time step represents one hour)

Note

Changes compared to Hanke Project Thesis:

  1. Rename "[High/Mid/Low] Voltage Powerline" to "[High/Mid/Low] Voltage Grid"

  2. Rename "[High/Low] Voltage Transformator" to "[High/Low] Voltage Transfer Grid"

Returns

es – Tessif energy system.

Return type

tessif.system_model.AbstractEnergySystem

Create the TransCnE system model scenarios combinations.

Created by Tim Hanke. Modified by Mathias Ammon.

Parameters

  • periods (int, default=24) – Number of time steps of the evaluated timeframe (one time step is one hour)

  • transformer_efficiency (int, default=0.99) – Efficiency of the grid transformers (must be a value between 0 and 1)

  • gridcapacity (int, default=60000) – Transmission capacity of the transformers of the gridstructure (at 0 the parts of the grid are not connected)

  • expansion (bool, default=False) – If True maximum grid capacity is subject to expansion.

Note

Changes compared to Hanke Project Thesis:

  1. Rename "Power Source [Voltage]" to "Deficit Source [Voltage]"

  2. Rename "Power Sinks [Voltage]" to "Excess Sinks [Voltage]"

  3. Rename "[High/Mid/Low] Voltage Powerline" to "[High/Mid/Low] Voltage Grid"

  4. Rename "[Voltage to Voltage] Transformator" to "[Voltage to Voltage] Transfer"

  5. Change gridcapacity parameter to reference the maximum outflow.

  6. Expansion capabilities are added to allow maximum grid capacity to be expanded

  7. Default transformer_efficiency is decreased to 0.93 to discourage energy circulation between to grid busses to dissipate surplus amounts.

  8. Outflow costs of 10 cost units per power unit are added to all Transfer components, to further discourage energy circulation between to grid busses to dissipate surplus amounts and to encourage local production and consumption.

Returns

es – Tessif energy system.
