Expand description
The PowerModelsDistribution MATHEMATICAL model as JSON (pmd-math-json).
PMD’s transform_data_model lowers an ENGINEERING model to the index
based, per unit MATHEMATICAL model its optimization problems are built
on: integer keyed bus, branch, switch, transformer, gen,
load, shunt, and storage tables, every value per unit on a bus
voltage base and the system power base, angles in radians, and
transformers decomposed into ideal two-winding units joined by a loss
model of virtual buses and branches. The map table records which
MATHEMATICAL objects each ENGINEERING object became, and bus_lookup
names each bus’s index.
The writer performs that lowering from the typed network,
following eng2math.jl, make_per_unit!, and calc_voltage_bases of PMD
v0.16: the same object names, source_ids, virtual element names, and
per unit conventions, so PMD reads the output as its own and the oracle
tests compare the two value by value. The reader inverts the
per unit scaling with the document’s own bases and folds the virtual
elements back through map, so a MATHEMATICAL document parses to the
same MulticonductorNetwork its ENGINEERING source would, with the
irreversible parts (winding power ratings, line lengths, Kron reduced
neutrals) restated and reported.
