Load Flow Studies

2015
Load flow analysis is essential to know the detailed description of a complex power network. Load flow solutions provide the basic computational techniques in order to determine the voltages at various buses and the power flowing through the elements of the system.

Probabilistic Load Flow

IEEE Transactions on Power Apparatus and Systems, 1974
The paper describes a method for evaluation of power flow which takes into consideration uncertainty of node data. The essence of the method is that the net loads are given as a set of values together with additional information on the frequency of its accuracy.

Load Flow Analysis

2002
The starting point of any analysis of power system will be the computation of complex voltages at all the busses. Load flow analysis is a computational tool for this purpose.

Forecasting data for load flow

Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat. No.04CH37521), 2004
In order to achieve a more secure and economic operation of a power system its state should be known not only in the present but some time ahead. Transmission system operators do not have the same security margins like they had in the past. Most of the tools of security assessment operate on-line and provide valuable input to the system operators ...

Load Flow Examples

2016
In this chapter we present results on three typical power systems. First is a basic 3-bus system. Reader should be able to check our results easily. The IEEE 30-bus and an ill-conditioned 43-bus system are also solved and results compared with standard Newton-Raphson results for the 30-bus system.

Augmented rectangular load flow model

IEEE Transactions on Power Systems, 2002
This paper presents some improvements to the load flow solution in rectangular coordinates. First, in an attempt to use as linear a model as possible, both the nodal equations and the bus constraints are retained. The Newton-Raphson (NR) method is then applied to the enlarged set of equations, and written in terms of bus voltages and currents.

Series load flow: A novel non-iterative load flow method

IEE Proceedings - Generation, Transmission and Distribution, 1998
A noniterative method for solving load flow equations is presented in the paper. The method is based on the Taylor series expansion of the inverse load flow function. Formulas to compute the Taylor series are derived and associated solution algorithms are developed.

Ecosystem flow networks: Loaded dice?

Mathematical Biosciences, 1991
An information-theoretic comparison of the topologies of observed ecosystem transfers and randomly constructed networks reveals that it is not easy to separate the members of the two sets. The distribution of ecosystem flow magnitudes, however, is seen to differ markedly from ordinary probability functions and to resemble the Cauchy or Pareto ...
