The Dispa-SET unit-commitment and optimal dispatch model
The Dispa-SET model is an open-source unit commitment and optimal dispatch model developed at the JRC. It focuses on the balancing and flexibility problems in the European power system.
It is written in GAMS with advanced input/output data handling and visualization routines in Python.
Three different formulations are available offering a trade-off between accuracy and computational complexity ( Linear Programming (LP), Mixed-Integer Linear Programming (MILP)). This allows to model a power system at any level of detail e.g. micro-grid, region, country, continent. A Pan-European scenario is included with the model as of version 2.3.
- Minimum and maximum power for each unit
- Power plant ramping limits
- Reserves up and down
- Minimum up/down times
- Load Shedding
- Mid term hydro-thermal scheduling
- 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
