Simulations or Fault Scenarios

After having defined a PowerGrid a simulation can be run.

Currently PowerDynamics supports the following fault/simulation types:

A specific scenario can be simulated for a given powergrid using the simulate function

Detailed Simulation/ Fault Type Documentation

Change Initial Conditions

PowerDynamics.ChangeInitialConditions — Type
ChangeInitialConditions(;node,var,f)

Keyword Arguments

  • node: number of the node
  • var: symbol of the variable to be perturbated
  • f: function for mapping the variable x to the perturbated value
source

AbstractPertubation types

PowerDynamics.AbstractPerturbation — Type
AbstractPerturbation(;)

An AbstractPerturbation can be uses to construct almost any type of perturbation that has a time span of a fault. Perturbations that are of type of AbstractPerturbation can use the same simulate function then. For example implementations of faults as type AbstractPerturbation see e.g. PowerPerturbation.

Keyword Arguments

  • tspan_fault: number of the node
source
PowerDynamics.LineFailure — Type
LineFailure(;line_name,tspan_fault)

The arguments line_name and tspan_fault specify the line that should be disconnected from the grid and the respective fault duration. For a list of lines the line_name is the index and for an OrderedDict it is the key of the line.

PowerDynamics.NodeParameterChange — Type
NodeParameterChange(;node, value, tspan_fault, var)

Keyword Arguments

  • node: number or name of the node
  • value: value of power during fault event
  • tspan_fault: PowerPerturbation timespan
  • var: symbol of parameter that is perturbed
source
PowerDynamics.NodeShortCircuit — Type
    NodeShortCircuit(;node,Y,tspan_fault)

Keyword Arguments

  • node: number or name of the node
  • Y: admittance of the short circuit
  • tspan_fault: short circuit timespan

Optional Keyword Arguments

  • var: symbol of the shunt admittance, default: :Y_n
source
PowerDynamics.PowerPerturbation — Type
PowerPerturbation(;node_number,fault_power,tspan_fault,var)

Keyword Arguments

  • node_number: number or name of the node
  • fault_power: value of power during fault event
  • tspan_fault: PowerPerturbation timespan
  • var: parameter symbol on the node that represents Power, default is :P
