/* - Calculate bus and branch weight In the following example, there are three branches connected to the bus. p1, ... p3 being the branch weight, branch weight follows power flow positive direction from->to. Bus weight is defined as sum of all out-going branch weight or sum of all in-coming branch weight - bus load p1 -> | | -> p2 bus weight = p2 = p1 + p3 + gen - load p3 -> | p1 -> | -> p2 | bus weight = p2 + p3 = p1 + gen - load | -> p3 - visit branches connected to a bus if for a bus, there is only one un-visited branch, then weight of the branch can be determined. This algorithm only applies to radial network. - visit bus if all branches connected to a bus are visited, the bus is said to have visited.

calculateBranchFlowDirection

public void calculateBranchFlowDirection()
                                  throws InterpssException

calculate branch power flow direction, without considering branch loss. Branch // loss will not change power flow direction in a radial network. branch.intFlag = 1, if flow direction fromBus->toBus, branch connection direction = branch flow direction branch.intFlag = 0, if flow direction fromBus<-toBus

Throws:

InterpssException - if there is loop in the network
