Nonparametric Probabilistic Optimal Power Flow

IEEE Transactions on Power Systems, 2022
With the increasing penetration of renewable energy, accurate and efficient probabilistic optimal power flow (POPF) calculation becomes more and more important to provide decision support for secure and economic operation of power systems. This paper develops a novel nonparametric probabilistic optimal power flow (N-POPF) model describing the ...

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), 2015
A 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 harmonic power flow for percentile evaluation

Canadian Conference on Electrical and Computer Engineering 2001. Conference Proceedings (Cat. No.01TH8555), 2002
This paper describes a new probabilistic method for harmonic analysis of multiconverter power systems which allows the evaluation of the percentiles of the voltage and current harmonics, that are the probabilistic quantities of interest in the most recent international recommendations or standards.

Probabilistic analysis of power flows

Proceedings of the Institution of Electrical Engineers, 1974
The 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 optimal power flow

Conference Proceedings. IEEE Canadian Conference on Electrical and Computer Engineering (Cat. No.98TH8341), 2002
This 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

Probabilistic Power Flow Analysis

2020
Modern power systems are quickly evolving as many fundamental changes are currently taking place. On the one hand, there is an accelerated market transformation. For example, the European Union (EU) is moving fast to a single European electricity market, thereby increasing the volume of energy trade between countries. As a consequence, the cross-border

Probabilistic Power Flow Solution with Graph Convolutional Network

2020 IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe), 2020
One 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

Approximate Probabilistic Power Flow

2017
Power flow analysis is a necessary tool for operating and planning Power systems. This tool uses a deterministic approach for obtaining the steady state of the system for a specified set of power generation, loads, and network conditions. However this deterministic methodology does not take into account the uncertainty in the power systems, for example
