  • GIS

    • Added ability to load geographic coordinates of indivdual zones inside config file (currently only applicable for electricity). An example file can be found inside the test directory

  • Heating sector

    • Added Heating zones analogue to electricity zones

    • Demand in each zone can now be covered by multiple units

    • Added Heat only generation technologies to the mix

    • Thermal storage can be attached directly to a unit or used as a standalone technology

    • Heating sector dispatch plots

    • Heat sector installed capacity and anual generation plot

  • Reserves

    • Added three new reserve forcasting methods: Exogenous, Percentage and Probablistic

    • CHP and power to heat units can now provide reserves

  • Hydrogen sector

    • Added new hydrogen technologies

    • H2 zones designed analoguos to the heating sector (i.e. one demand per H2 node and multiple technologies patricipating to the same H2 market)

  • Water-energy nexus

    • Water consumption and water withdrawal parameters used by the cooling systems inside the thermal generators are added to the database. These indicators are useful for the assessment of the water-energy nexus.

  • RES curtailment

    • RES curtailment is now an optimization variable

    • Curtailment cost can be specified in the cinfig file. If the cost is > 0 EUR/MWh and there is some curtailment, shadow prices will be negative (this alligns closer to the real world markets where exces wind generation results in negative market clearing prices)

  • New model outputs (i.e. Results)

    • OutputCurtailedHeat, OutputCurtailedPower - Hourly time series of curtailments

    • ShadowPrice_2U, ShadowPrice_2D, ShadowPrice_3U - Hourly timeseries of balancing prices

    • HeatShadowPrice, OutputH2ShadowPrice - Hourly timeseries of heat and H2 prices

    • StorageShadowPrice - Hourly timeseries of storage prices (i.e. intra temporal price of the next MWh dispatched by the storage units)

    • OutputPtLDemand, OutputH2Output - Hourly timeseries of the Power to liquid demand (fixed anual value distributed to hourly values through MTS) and Power output of H2 units

    • OutputReserve_2U, OutputReserve_2D, OutputReserve_3U - Hourly timeseries of the power reserved for the balancing

    • ShadowPrice_RampUp_TC, ShadowPrice_RampDown_TC - Hourly timeseries of ramping costs (i.e. if dispatchable unit needs to be switched on/off the price would reflect the start-up shut-down costs specified in the power plants database)

    • OutputRampRate - Hourly timeseries of ramping rates

    • OutputStartUp, OutputShutDown - Hourly timeseries of start-up and shut-down events (i.e. if one powerplant has several Nunits of which 2 are switched on or 7 are switched off this number would be visible here)

    • OutputCostStartUpH, OutputCostRampUpH - Hourly timseries of startup and tamping costs

    • OutputEmissions - Hourly timseries of zonal CO2 intesity (i.e. value will be >0 if fossil generators are on and 0 if demand is 100% satisfied by the RES)

    • OutputStorageSlack - Unsatisifed minimum storage constraint at the end of the optimization horizon (one value per horizon)

  • Post-processing

    • (plot_zone) New fuel/technology-types added to the plots (color codes are now slightly improved)

    • (plot_zone) Power consumption and storage charging (storage input) added to the energy generation plots. This gives us more insigts into energy conversion/transmission

    • (plot_zone) Added generation share plot (i.e. expressed in terms of % rather than absolute values)

    • (plot_zone_capacities) Peak power consumption line added to the installed capacities plot. This gives us more insights into sector-coupling links

    • (plot_tech_cap) Added installed storage capacity plot. It shows how much storage capacity is located in individual zones

    • (plot_power_flow_tracing_matrix) Added power flow tracing matrix. Indication of local generation and exports to neighboring ones

    • (plot_net_flows_map) Added power feed plot. Indication of net importing/exporting zones (WRNING! this plots take a while to generate. Sometimes Stamen server is timed out and background pictures are not loaded properly resulting in “http.client.IncompleteRead: IncompleteRead(xxxxx bytes read, yyyy more expected)”. Currently the only way to fix this is to try the plotting function at a later point in time.

    • (plot_line_congestion_map) Added line congestion plot. Indication of the congested lines and directions (i.e. line between Z1 and ZZ3 is congested 60% of the time, meaning that Flow/MaxFLow = 1)

    • (get_result_analysis) Added a more detailed statistical system representation such as Total and peak/max values for individual variables of intrest,

    • (get_result_analysis) Added a more detailed statistical zonal representation same as above but filtered by zone and summarized under ZoneData

    • (get_result_analysis) Added a more detailed statistical unit representation same as above but filtered by units and summarized under UnitData

    • (get_result_analysis) Added a more detailed statistical fuel representation same as above but filtered by fuel and summarized under FuelData

    • (get_result_analysis) Added water consumption which can be filtered on per Zone/Unit level and is summarized under WaterConsumptionData

    • (get_result_analysis) Added a more detailed storage analysis summarized under StorageData

Bugfixes

  • Variable time step

    • The pre-processing and the GAMS file have been updated to handle different time steps (not only one hour)

    • This is currently restricted to three time steps: 15min, 1h, 24h

    • The input data whose time step is lower than the desired one is averaged

  • Miscellaneous

    • Improved error handling

Version 2.4

  • Mid-term scheduling

    • The yearly storage level profiles can now be calculated internally (i.e. without providing exogenous profiles).

    • A first, simplified version of dispa-set is run over a whole year to generate these profiles during the pre-processing phase

    • This option is activated in the config file and is transparent for the user.

  • Flexible Demand:

    • To model demand-side management, it is now possible to define a share of the demand curve as “flexible”

    • In this flexible demand, the load can be shifted from one hour to the other

    • The maximum flexibility is characterized by the equivalent number of storage hours for the shifted load, which is defined as parameter in the configuration file.

  • Power-to-heat units

    • P2HT units (heat pumps, electrical heater) have now been added

    • They are coupled to a heat demand and possibly to a thermal storage capacity

    • COP can be defined as temperature-dependent. An additional input with temperature times for each zone has been defined.

  • Transmission prices have been added to the pre-processing and can now be fully parametrized

  • Fuel Prices can now be country-specific

  • Input data in the csv files can now be defined with time stamps from any year or with a numerical index

  • Post-processing:

    • Improved dispatch plot with shifted, shed loads and electricity consumption from P2HT units

    • Storage levels are now differentiated by technology

  • Miscellaneous:

    • Multiple bug fixes, code improvement and usability improvement.

    • All config files and the example scripts have been checked and cleaned

    • New formulation of the clustering function with significant simulation time improvements

    • The Pyomo version of Dispa-SET has now been removed since it was no longer up-to-date

    • The end-of horizon reservoir level is no longer a firm constraint. A water value can be defined to impose a price on the unmet level requirements.

    • Excel configuration files are now subject to versioning, which ensures backward compatibility with older configuration files.

    • Countries are now renamed into “zones” in all API functions.

    • The option to cache csv file data when loading has been removed

    • Implemented a more robust versioning system

Version 2.3

  • Input Data:

    • A complete EU dataset has been included to the repository for the year 2016.

    • More information: Dispa-SET for the EU28.

  • Reformulation of the reserve constraints:

    • Secondary reserves are now covered by spinning units only.

    • Tertirary reserves can also be covered by quick start units.

    • In total, three different reserve markets are now considered: Secondary up; Secondary down; and Tertiary up

  • Implementation of a new formulation (integer clustering) for power plant related constraints. This formulation divides the simulation time by a factor higher than 10 and allows extending the geographical scope of Dispa-SET. There are now four standard model formulations, which can be run with the same input data:

    • Standard formulation: low capacity or highly flexible units are merged

    • No clustring: all units are considered individually

    • LP clustering: all units are aggregated by technology and binary constraints are removed

    • Integer clustering: a representative unit is considered for each technology and multiplied N times.

  • Improved pre-processing:

    • Improved log message during input data checks

    • New config files to test the different clustering methods

    • Added functions to perform parametric studies

    • Example scripts for Monte Carlo analyses using lating hypercube samplings

  • Improved post-processing:

    • Netting interconnections in dispatch plots

    • New colour palette and polished dispatch plot

    • New fuels included

    • Improved representation of curtailment

  • External dependencies:
  • Python 3.7:

    • Dispa-SET now runs exclusively on Python 3.7.

    • The compatibility with previous Python versions (2.7, 3.6) is not guaranteed anymore.

  • Miscellaneous:

Version 2.2

  • Inclusion of CHP, power2heat and thermal storage (these new features can be tested by running the config file for Cyprus: ‘ConfigFiles/ConfigCY.xlsx’)

  • Bug fixes

  • Improved user interface

Version 2.1

  • Major refactoring of the folder structure

  • New data included in the database

  • Inclusion of the LP formulation (in addition to the MILP)
