Formatted Abstract/Summary
In planning and operation of power systems uncertainties introduced by stochastic behaviour of loads and generators as well as the inherent error of predictions for future scenarios have to be taken into account. Information about the probability of violation of operational constraints is a useful parameter, especially for network planning. Because of the large amount of possible operational states that have to be evaluated when considering the stochastic nature of certain loads and generators, traditional load flow calculation is not a promising basis for deployment on models of large networks. This is the domain of probabilistic load flow calculation. In extension to existing convolution based probabilistic load flow methods an approach for the modelling and consideration of correlations between the input parameters is presented in this paper. Aspects like computational burden and achievable precision are discussed in detail.
