Technologies that may be merged into one clustered object

Groups a model's single-region technologies by STRUCTURE – input, output and aux commodities, and input groups. Only technologies with the same structure can become clusters of one object, because a cluster is a variant of the same process, not a different one: a coal plant and a gas plant have different inputs and stay separate however alike their costs look.

Usage

get_process_groups(x, regions = NULL)

Arguments

x

a model, repository, or a list of objects.

regions

optional character vector; keep only technologies living in these regions.

Value

A data.frame, one row per group, with group (the common name stem, and the name the merged object will take), signature, n, members and regions (comma-separated). Technologies that span several regions are not grouped and do not appear.

Details

This is the first step of a clustered aggregation: it names the families aggregate_model_regions() can turn into clusters, and those names are the keys of its clusters argument.

See also

process_cluster_sweep() to choose each family's k, aggregate_model_regions() to apply it.

Examples

ek  <- topia$modules$electricity$R3
mod <- newModel("TOPIA", data = ek$repo,
                calendar = topia$modules$calendars$s4_h24,
                region = ek$regions,
                horizon = topia$modules$horizons$base,
                discount = 0.05)
mod <- setGeoscale(mod, ek$geoscale)
