# Datasets

To run a simulation, it is necessary to provide a simulation model and input timeseries (see [modules chapter](core_modules) for which timeseries are needed).
A simulation model can be constructed via API (see [example](https://gitlab.com/sintef-energy/Trident/partner/Trident-notebooks/api_examples/domain_example.ipynb)), or via built-in loaders.

## LTMV10 loader

In order to integrate with older systems, `Trident` supports loading the simulation model and timeseries from a `LTMv10` dataset. Here we provide an overview of the subset of files `Trident` makes use of, and that needs to be provided in order for the different modules to function properly.

The files can be made manually by a user (or their internal system), by a `ltm` application or by `LTM api`.

### PRISAVSNITT.DATA

User generated.

Required by:
- `ModuleTransmission`

### model.h5

Can be generated by the programs `markedmodelprep`, `EMPS` or `Saminn` (old v9).

Required by:
- `ModuleHydro`
- `ModuleHydroBasic`
- `ModuleLoad`
- `ModuleSolar`
- `ModuleThermal`
- `ModuleWind`

### BRENSEL.ARCH

User generated.

Required by:
- `ModuleFuelType`

### TidsserieData.h5

Can be generated by either `konvtiltser` or the `LTM api`.

Required by:
- `ModuleThermal`
- `ModuleExchange`
- `ModuleLoad`
- `ModulePriceElasticity`

### ProfTemp/*ARCH

Generated when upgrading from `LTMv9` to `LTMv10` using `update_10`, but new entries in the directory can be made manually by the user.

Required by:
- `ModuleTemperatureCorrection`

### wind_data.h5

Generated from V30 (can potentially have other names) files using `update_10`.

Required by:
- `ModuleWind`

### constraints.xml

Generated by `FanSI`.

Required by:
- `ModuleTransmission (with ramping enabled)`

### startkostnader.dat

User generated.

Required by:
- `ModuleThermal (with startup costs enabled)`

### <area_name>.ENMD

Can be generated and edited using `nnmdat` in v9, or `ltm` in v10.

Required by:
- `ModulePriceElasticity`
- `ModuleFuelType`

### DYNMODELL.OM<area_name>

Generated when running the program `detmod`.

Required by:
- `ModuleHydro`
- `ModuleHydroBasic`

### SYSTEM.SMAG

Generated by `ltm` using information from the file reservoir.star.

Required by:
- `ModuleHydro`
- `ModuleHydroBasic`

### exogenous_prices.h5

Generated when running `update_10` if references to exogenous prices exists. Can otherwise be generated or updated using `ltm`.

Required by:
- `ModuleExchange`

### VVERD_xxx.SAMK

Result data from `Emps` when running water value calculations.

Required by:
- `EndValueBendersCutModule` (if SOVNWaterValue.h5 is not provided)

### SOVNWaterValue.h5

Result data from `FanSI`.

Required by:
- `EndValueBendersCutModule` (if VVERD_xxx.SAMK is not provided)

### MASKENETT.DATA

User generated.

Required by:
- `ModuleTransmission`

### CAP_FILE.H5

Generated when running `update_10`. Can also be generated or edited using `LTM API`.

Required by:
- `ModuleTransmission`

### Dellast_data.h5

Result file from either `emps.exe` or `saminn.exe`. Required if you want to do scenario depended temperature correction, but not use `ModuleTemperatureCorrection`.

Required by:
- `ModuleExchange`
