Probabilistic Load Flow Including Wind Power Generation
IEEE Transactions on Power Systems, 2011 In this paper, a procedure is established for calculating the load flow probability density function in an electrical power network, taking into account the presence of wind power generation. The probability density function of the power injected in the network by a wind turbine is first obtained by utilizing a quadratic approximation of its power ...

A novel probabilistic load model and probabilistic power flow
2015 IEEE 28th Canadian Conference on Electrical and Computer Engineering (CCECE), 2015A precise planning and operation of the power system requires an accurate load model that account for the load stochastic nature. In addition, the probabilistic power flow is a vital tool for power system engineers. Hence, this paper presents a novel probabilistic load model that models the load with an average load curve in addition to a probabilistic

Probabilistic analysis of power flows
Proceedings of the Institution of Electrical Engineers, 1974The paper describes and examines a technique which permits the power-flow problem in a power system to be analysed probabilistically instead of using normal deterministic methods. All the nodal loads and generation are defined as random variables and the power flow in each line is computed in terms of a probability density function. The expected values

Probabilistic Power Flow Solution with Graph Convolutional Network
2020 IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe), 2020One fundamental issue in power grid is the power flow calculation. Due to the uncertainty in system variables, recent research works often concentrate on the probabilistic power flow (PPF). But traditional algorithms cannot combine high accuracy with fast calculation speed. In this paper, we revisit the probabilistic power flow problem, aiming to boost

Probabilistic optimal power flow
Conference Proceedings. IEEE Canadian Conference on Electrical and Computer Engineering (Cat. No.98TH8341), 2002This paper presents a new formulation and solution approach to a probabilistic optimal power flow (POPF) problem. In this formulation, system demand is taken as a random vector of correlated variables, which allows us to consider the dependence between load types and locations. The POPF is clearly formulated and the optimality conditions are considered
