Get the buses in a System
You can access all the buses in a System to view or manipulate their data using two key functions: get_components or get_buses.
Option 1a: Get an iterator for all the buses
Use get_components to get an iterator of all the AC buses in an existing system:
julia> bus_iter = get_components(ACBus, system)ACBus Counts: ACBus: 73
The iterator avoids unnecessary memory allocations if there are many buses, and it can be used to view or update the bus data. For example, we can set the base voltage of all buses to 330 kV:
julia> for b in bus_iter set_base_voltage!(b, 330.0) end
Option 1b: Get a vector of all the buses
Use collect to get a vector of the buses instead of an iterator, which could require a lot of memory:
julia> buses = collect(get_components(ACBus, system))73-element Vector{ACBus}: ACBus(202, Bacon, ACBusTypes.PV = 2, -0.1877810214196211, 1.04844, (min = 0.95, max = 1.05), 330.0, Area(2, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(22.0, 5.29, 1.08, Dict{String, Any}()), Dict{String, Any}()) ACBus(321, Cobb, ACBusTypes.PV = 2, 0.21539492271297458, 1.05, (min = 0.95, max = 1.05), 330.0, Area(3, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(37.0, 3.33, 0.68, Dict{String, Any}()), Dict{String, Any}()) ACBus(322, Cole, ACBusTypes.PV = 2, 0.3153659860038082, 1.05, (min = 0.95, max = 1.05), 330.0, Area(3, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(37.0, 3.33, 0.68, Dict{String, Any}()), Dict{String, Any}()) ACBus(102, Adams, ACBusTypes.PV = 2, -0.1364470483941135, 1.04783, (min = 0.95, max = 1.05), 330.0, Area(1, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(12.0, 5.29, 1.08, Dict{String, Any}()), Dict{String, Any}()) ACBus(117, Aston, ACBusTypes.PQ = 1, 0.19956391373276003, 1.04783, (min = 0.95, max = 1.05), 330.0, Area(1, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(17.0, 3.33, 0.68, Dict{String, Any}()), Dict{String, Any}()) ACBus(324, Curie, ACBusTypes.PQ = 1, 0.02279504722859714, 1.01046, (min = 0.95, max = 1.05), 330.0, Area(3, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(36.0, 6.109999999999999, 1.23, Dict{String, Any}()), Dict{String, Any}()) ACBus(121, Attlee, ACBusTypes.PV = 2, 0.22840303616101354, 1.05, (min = 0.95, max = 1.05), 330.0, Area(1, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(17.0, 3.33, 0.68, Dict{String, Any}()), Dict{String, Any}()) ACBus(206, Bajer, ACBusTypes.PQ = 1, -0.28198796032281825, 1.03259, (min = 0.95, max = 1.05), 330.0, Area(2, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(22.0, 5.29, 1.08, Dict{String, Any}()), Dict{String, Any}()) ACBus(217, Bates, ACBusTypes.PQ = 1, 0.15390994022494278, 1.04847, (min = 0.95, max = 1.05), 330.0, Area(2, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(27.0, 3.33, 0.68, Dict{String, Any}()), Dict{String, Any}()) ACBus(103, Adler, ACBusTypes.PQ = 1, -0.1258539470320591, 1.01085, (min = 0.95, max = 1.05), 330.0, Area(1, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(11.0, 4.33, 0.88, Dict{String, Any}()), Dict{String, Any}()) ⋮ ACBus(218, Bayle, ACBusTypes.PV = 2, 0.17444094634785287, 1.05, (min = 0.95, max = 1.05), 330.0, Area(2, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(27.0, 3.33, 0.68, Dict{String, Any}()), Dict{String, Any}()) ACBus(219, Bede, ACBusTypes.PQ = 1, 0.07351902768053274, 1.03946, (min = 0.95, max = 1.05), 330.0, Area(2, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(25.0, 3.09, 0.63, Dict{String, Any}()), Dict{String, Any}()) ACBus(114, Arnold, ACBusTypes.PV = 2, -0.03020396990331307, 1.04401, (min = 0.95, max = 1.05), 330.0, Area(1, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(16.0, 6.109999999999999, 1.23, Dict{String, Any}()), Dict{String, Any}()) ACBus(207, Baker, ACBusTypes.PV = 2, -0.23502708427110763, 1.03973, (min = 0.95, max = 1.05), 330.0, Area(2, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(22.0, 5.29, 1.08, Dict{String, Any}()), Dict{String, Any}()) ACBus(214, Barry, ACBusTypes.PV = 2, -0.08177199158151313, 1.04335, (min = 0.95, max = 1.05), 330.0, Area(2, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(26.0, 6.109999999999999, 1.23, Dict{String, Any}()), Dict{String, Any}()) ACBus(212, Barkla, ACBusTypes.PQ = 1, -0.09168807972671891, 1.01921, (min = 0.95, max = 1.05), 330.0, Area(2, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(23.0, 3.7, 0.76, Dict{String, Any}()), Dict{String, Any}()) ACBus(113, Arne, ACBusTypes.REF = 3, 0.0, 1.03943, (min = 0.95, max = 1.05), 330.0, Area(1, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(14.0, 2.65, 0.54, Dict{String, Any}()), Dict{String, Any}()) ACBus(203, Baffin, ACBusTypes.PQ = 1, -0.18281503609892163, 1.01886, (min = 0.95, max = 1.05), 330.0, Area(2, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(21.0, 4.33, 0.88, Dict{String, Any}()), Dict{String, Any}()) ACBus(112, Archer, ACBusTypes.PQ = 1, -0.042310969858547334, 1.02024, (min = 0.95, max = 1.05), 330.0, Area(1, 0.0, 0.0, 0.0, Dict{String, Any}()), LoadZone(13.0, 3.7, 0.76, Dict{String, Any}()), Dict{String, Any}())
Option 2a: Get the buses in an Area or LoadZone
Use get_buses to get a vector of buses when you know which Area or LoadZone you are interested in.
First, we select an Area:
julia> show_components(Area, system) # See available AreasArea ┌──────┐ │ name │ ├──────┤ │ 1 │ │ 2 │ │ 3 │ └──────┘julia> area2 = get_component(Area, system, "2"); # Get Area named 2
Then call get_buses for that Area:

Option 2b: Get buses by ID number

Example getting buses with ID numbers from 101 to 110:

You can combine this with Option 1 to first view all the bus numbers if needed:
