JuMP Model Variables

CommonOPF provides some patterns for storing variables so that we can provide common functionality across power flow models. Currently the main functionality that relies on variable access-patterns is Results. Note that you do not have to use the CommonOPF variable access patterns to use the Network model and other methods like the graph analysis stuff.

Variable Containers

CommonOPF provides a variable container pattern for the JuMP.Models built in the CommonOPF dependencies so that we can support common functionality, especially for retrieving results from solved models. The pattern is a Dict{String, Dict{Int, Any}} that has:

1. bus or edge labels first
2. and integer time step keys second.

For example, a single-phase model that stores the "net_real_power_injection" variable in model[:p] will store the real power variable for bus "b1" in model[:p]["b1"][1].
