Cascade2: Calculate the effects of a cascade

In JonnoB/PowerGridNetworking: Power-grid network simulation in R

Description

Iterates through the network removing edges until no edges are over the line limit and the network has stabilised.

Usage

Cascade2(
  g,
  g0 = NULL,
  node_power = node_power,
  edge_status = edge_status,
  AZero,
  LineProperties,
  Generation = "Generation",
  Demand = "Demand",
  EdgeName = "Link",
  VertexName = "name",
  Net_generation = "BalencedPower",
  power_flow = "PowerFlow",
  edge_limit = "Link.Limit"
)

Arguments

g	An igraph object. The graph at its current state in the attack process
g0	An igraph object. An optional value that defines the reference network
node_power	A vector of the current node power for this round
edge_status	A vector of current edge status, this is an integer vector of 4 levels 0-3
AZero	A matrix. THe transmission matrix of the network
LineProperties	The diagonal Line properties matrix
Generation	The name of the node generation variable. A character string.
Demand	the name of the node Load variable. A character string.
EdgeName	The variable that holds the edge names, a character string.
VertexName	The variable that holds the names of the nodes, to identify the slack ref. a character string
Net_generation	The name that the net generation data for each node is held in
power_flow	A character string. This value indicates the name of the edge attribute that holds power flow, the default is "PowerFlow"
edge_limit	A character string. This value indicates the name of the edge attribute that holds the edge limit, the default is "Link.Limit"

Details

This version of cascade works with the attack_the_grid function. It is confusing as it is called cascade2 not one but there we go.

The function outputs a list of 3 elements. the first element is the updated igraph object after the cascade has terminated. The second element is a vector of node power values, the third element is a vector of the edge status.
