Variables

We provide the following methods to provide a compositional approach for defining common variables used in power flow models. These methods should always be defined over "GenericPowerModel".

PowerModels.getstart — Function.

extracts the start value

source
PowerModels.variable_active_branch_flow — Function.

variable: p[l,i,j] for (l,i,j) in arcs

source
PowerModels.variable_active_branch_flow_ne — Function.

variable: -ne_branch[l]["rate_a"] <= p_ne[l,i,j] <= ne_branch[l]["rate_a"] for (l,i,j) in ne_arcs

source
PowerModels.variable_active_dcline_flow — Function.

variable: p_dc[l,i,j] for (l,i,j) in arcs_dc

source
PowerModels.variable_active_generation — Function.

variable: pg[j] for j in gen
