Probabilistic power flow

Loads are uncertain: fuzzy vs probabilistic
Radially currents are random variables and what adds up are random variables
Types of random variables for loads
Mean values add up, as E(.) is a linear operator
std(.) is not linear
Near the top (of the tree), the current’s distribution is more concentrated near the mean value: smaller std
For security reasons the system is planned for values far from mean values (2 std’s); numerical values for currents in a node do not add up
Probabilistic analysis if the network is meshed: an introduction to Monte Carlo
What are the final results of a probabilistic analysis
