The Dispa-SET model is mainly developed within the “Joint Research Centre” of the European Commission and focuses on the balancing and flexibility problems in European grids .
It is written in GAMS an Python (Pyomo) and uses csv files for input data handling. The optimisation is defined as a Linear Programming (LP) or Mixed-Integer Linear Programming (MILP) problem, depending on the desired level of accuracy and complexity. Continuous variables include the individual unit dispatched power, the shedded load and the curtailed power generation. The binary variables are the commitment status of each unit. The main model features can be summarized as follows:
- Minimum and maximum power for each unit
- Power plant ramping limits
- Reserves up and down
- Minimum up/down times
- Load Shedding
- Pumped-hydro storage
- Non-dispatchable units (e.g. wind turbines, run-of-river, etc.)
- Start-up, ramping and no-load costs
- Multi-nodes with capacity constraints on the lines (congestion)
- Constraints on the targets for renewables and/or CO2 emissions
- Yearly schedules for the outages (forced and planned) of each units
- CHP power plants and thermal storage
- Different clustering methods
The demand is assumed to be inelastic to the price signal. The MILP objective function is therefore the total generation cost over the optimization period.
Libraries used and requirements
Dispa-SET in the scientific literature
In the past years, Dispa-SET has been used in various scientific works covering different geographical areas and with different focus points. The works for which scientific articles have been published are summarized hereunder:
- Contribution of hydropower for flexibility services in the European power system .
- Ongoing work aiming at coupling the JRC-EU-TIMES model with Dispa-SET by generating simplified variable RES flexibility constraints .
- Impact of Electric Vehicle deployment in The Netherlands .
- Open-source model of the Balkans area, with some simulations involving high shares of renewables .
- Available technical flexibility to balance variable RES generation in Belgium
- Comparison of clustering formulations
The Dispa-SET project is relatively recent, and a number of improvements will be brought to the project in a close future:
- Grid constraints (DC power-flow)
- Stochastic scenarios
- Modelling of investment and capacity expansion
- Modeling of the ancillary markets
