The API behind Antares Web comes with a Variant Manager allowing to edit a study. Functions from {antaresEditObject} can be used send commands to the API or generate commands to be sent to the API.

Path to simulation and variant creation

First we need to declare which study we are going to use:

antaresRead::setSimulationPathAPI(
  host = "http://localhost:8080",
  study_id = "70a08fae-da67-444a-b2ed-df4c0f956a31", 
  token = NULL, 
  simulation = "input"
)

Then we can create a new variant from our study or use one created through the web interface:

# Create new variant
createVariant("variant-1")

# use an existing one
useVariant("variant-2")

A third option is to mock the web server behavior, it can be useful if we are offline or if we just want to generate API commands to be use afterwards:

mockSimulationAPI()

API editing mode

{antaresEditObject} allow to use two modes to use the API:

async: record all API calls, but nothing is sent to the server, commands can be retrieved after calling {antaresEditObject}’s functions
sync: send query to the API each time a function is used (commands are also internally recorded if needed).

setAPImode("async")
# or
setAPImode("sync")

Default is to used async mode. When using mockSimulationAPI() only async mode is available.

Get / export variant management commands

Variant commands generated after calling functions like createArea(), createLink(), … can be retrieved at all time with:

getVariantCommands()

Last command generated can be viewed with:

getVariantCommands(last = TRUE)
# or use a numeric to get the last N commands
getVariantCommands(last = 3)

You can also filter type of commands with:

getVariantCommands(actions = "create_area")

Export commands with:

writeVariantCommands("path/to/commands.json")

Usage example

Below are listed all functions from {antaresEditObject} that can be used with the API. These functions will include the following badge in their documentation:

Create an area

Create a new area:

createArea(name = "area01")
#> ℹ Command create_area registered, see all commands with `getVariantCommands()`
createArea(name = "area02")
#> ℹ Command create_area registered, see all commands with `getVariantCommands()`
createArea(name = "area03")
#> ℹ Command create_area registered, see all commands with `getVariantCommands()`
getVariantCommands()
#> [
#>   {
#>     "action": "create_area",
#>     "args": {
#>       "area_name": "area01"
#>     }
#>   },
#>   {
#>     "action": "create_area",
#>     "args": {
#>       "area_name": "area02"
#>     }
#>   },
#>   {
#>     "action": "create_area",
#>     "args": {
#>       "area_name": "area03"
#>     }
#>   }
#> ]

Create a second area with some default parameters:

createArea(
  name = "area04", 
  filtering = filteringOptions(filter_synthesis = c("hourly", "daily"))
)
#> ℹ Command create_area registered, see all commands with `getVariantCommands()`
#> ℹ Command update_config registered, see all commands with `getVariantCommands()`
getVariantCommands()
#> [
#>   {
#>     "action": "create_area",
#>     "args": {
#>       "area_name": "area01"
#>     }
#>   },
#>   {
#>     "action": "create_area",
#>     "args": {
#>       "area_name": "area02"
#>     }
#>   },
#>   {
#>     "action": "create_area",
#>     "args": {
#>       "area_name": "area03"
#>     }
#>   },
#>   {
#>     "action": "create_area",
#>     "args": {
#>       "area_name": "area04"
#>     }
#>   },
#>   {
#>     "action": "update_config",
#>     "args": {
#>       "target": "input/areas/area04/optimization/filtering",
#>       "data": {
#>         "filter-synthesis": "hourly, daily",
#>         "filter-year-by-year": "hourly, daily, weekly, monthly, annual"
#>       }
#>     }
#>   }
#> ]

You can also edit an area or remove it:

createArea(name = "area000")
#> ℹ Command create_area registered, see all commands with `getVariantCommands()`
# editArea(name = "area000", ...)
removeArea(name = "area000")
#> ℹ Command remove_area registered, see all commands with `getVariantCommands()`
getVariantCommands(last = TRUE)
#> [
#>   {
#>     "action": "remove_area",
#>     "args": {
#>       "id": "area000"
#>     }
#>   }
#> ]

Create a link

Create a new link between two areas like this:

createLink(from = "area01", to = "area02")
#> ℹ Command create_link registered, see all commands with `getVariantCommands()`
#> ℹ Command replace_matrix registered, see all commands with `getVariantCommands()`
#> ℹ Command replace_matrix registered, see all commands with `getVariantCommands()`
createLink(from = "area01", to = "area03")

#>       "matrix": [[0],[0],[0],[0],[0],[0]] [truncated]...
#>     }
#>   }
#> ]

Edit an existing link with:

editLink(
  from = "area01", 
  to = "area02",
  dataLink = matrix(data = c(rep(9, 8760*2), rep(6, 8760*6)), ncol = 8)

#>       "matrix": [[9],[9],[9],[9],[9],[9]] [truncated]...
#>     }
#>   }
#> ]

Remove a link with:

removeLink(from = "area01", to = "area03")
#> Link doesn't exist
#> NULL
getVariantCommands(last = TRUE)
#> [
#>   {
#>     "action": "replace_matrix",

#>     }
#>   }
#> ]

Edit a cluster with:

createCluster(
  area = "area02", 
  cluster_name = "clus02"
)
editCluster(
  area = "area02", 
  cluster_name = "clus02", 
  unitcount = 5L
)
getVariantCommands(last = TRUE)

Remove a cluster with (removeCluster() has been updated with endpoint and no longer uses an api command ):

createCluster(
  area = "area02", 
  cluster_name = "clus000"
)
removeCluster(
  area = "area02", 
  cluster_name = "clus000"
)
getVariantCommands(last = TRUE)

Create a binding constraint

Create a new binding constraint with:

createBindingConstraint(
  name = "myconstraint",
  values = NULL,
  enabled = FALSE,
  timeStep = "hourly",
  operator = "both",
  coefficients = c("area01%area02" = 1)
)
#> ℹ Command create_binding_constraint registered, see all commands with `getVariantCommands()`
getVariantCommands(last = TRUE)
#> [
#>   {
#>     "action": "create_binding_constraint",
#>     "args": {
#>       "name": "myconstraint",
#>       "enabled": false,
#>       "time_step": "hourly",
#>       "operator": "both",
#>       "filter_year_by_year": "hourly, daily, weekly, monthly, annual",
#>       "filter_synthesis": "hourly, daily, weekly, monthly, annual",
#>       "coeffs": {
#>         "area01%area02": [
#>           1
#>         ]
#>       }
#>     }
#>   }
#> ]

You can edit a binding constraint with editBindingConstraint() and remove one with removeBindingConstraint().

Update settings

Update general settings:

updateGeneralSettings(mode = "Adequacy", generate = c("thermal", "hydro"))
#> ℹ Command update_config registered, see all commands with `getVariantCommands()`
getVariantCommands(last = 2)
#> [
#>   {
#>     "action": "update_config",
#>     "args": {
#>       "target": "settings/generaldata/general/mode",
#>       "data": "Adequacy"
#>     }
#>   },
#>   {
#>     "action": "update_config",
#>     "args": {
#>       "target": "settings/generaldata/general/generate",
#>       "data": "thermal, hydro"
#>     }
#>   }
#> ]

Update input settings:

updateInputSettings(import = c("hydro", "thermal"))
#> ℹ Command update_config registered, see all commands with `getVariantCommands()`
getVariantCommands(last = TRUE)
#> [
#>   {
#>     "action": "update_config",

#>       "target": "settings/generaldata/input/import",
#>       "data": "hydro, thermal"
#>     }
#>   }
#> ]

Update optimization settings:

updateOptimizationSettings(
  simplex.range = "week",
  power.fluctuations = "minimize ramping"
)
#> ℹ Command update_config registered, see all commands with `getVariantCommands()`
#> ℹ Command update_config registered, see all commands with `getVariantCommands()`
getVariantCommands(last = 2)
#> [
#>   {
#>     "action": "update_config",
#>     "args": {
#>       "target": "settings/generaldata/optimization/simplex-range",
#>       "data": "week"
#>     }
#>   },
#>   {
#>     "action": "update_config",
#>     "args": {
#>       "target": "settings/generaldata/other preferences/power-fluctuations",
#>       "data": "minimize ramping"
#>     }
#>   }
#> ]

Update output settings:

updateOutputSettings(
  synthesis = TRUE,
  storenewset = FALSE,
  archives = c("load", "wind")
)
#> ℹ Command update_config registered, see all commands with `getVariantCommands()`
getVariantCommands(last = TRUE)
#> [
#>   {
#>     "action": "update_config",
#>     "args": {
#>       "target": "settings/generaldata/output/archives",
#>       "data": "load, wind"
#>     }
#>   }
#> ]

Scenario builder

Read data from scenario builder (here’s it’s empty since we’re mocking the API):

readScenarioBuilder()
#> list()

Create new data to use as scenario builder, since we’re mocking the API parameters must be set explicitly, otherwise thez are retrieved from the study.

my_scenario <- scenarioBuilder(n_scenario = 3, areas = c("area01", "area02"), n_mc = 10)
my_scenario
#>        [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
#> area01 "1"  "2"  "3"  "1"  "2"  "3"  "1"  "2"  "3"  "1"  
#> area02 "1"  "2"  "3"  "1"  "2"  "3"  "1"  "2"  "3"  "1"

Then you can update the scenario builder itself:

updateScenarioBuilder(ldata = my_scenario, series = "load")
#> ℹ Command update_config registered, see all commands with `getVariantCommands()`
getVariantCommands(last = TRUE)
#> [
#>   {
#>     "action": "update_config",
#>     "args": {
#>       "target": "settings/scenariobuilder/Default Ruleset",
#>       "data": {"l,area01,0":"1","l,area01,1":"2","l,area01,2":"3","l,area01,3":"1","l,area01,4":"2","l,area01,5":"3"} [truncated]...
#>     }
#>   }
#> ]

writeInputTS("area01", type = "solar", data = matrix(rep(4, 8760*2), nrow = 8760))
#> ℹ Command replace_matrix registered, see all commands with `getVariantCommands()`
getVariantCommands(last = TRUE)

#> ℹ Command replace_matrix registered, see all commands with `getVariantCommands()`
getVariantCommands(last = TRUE)
