This paper extends to the load flow problem the factorized solution methodology recently developed for equality-constrained state estimation. This is done by considering a redundant set of initial conditions in order to transform the undetermined system arising in the first linear stage into an overdetermined one.

Proceedings of the 28th IEEE Conference on Decision and Control, 2003
The use of Newton-Raphson load flows to locate type-one equilibria for determining domains of attraction for transient stability analysis or for examining voltage collapse has become common. It is known that Newton's method for real equations can produce true fractals behavior.

The load flow study has been at the center of studies made for designing and operating power systems for many years. It is well known that forecasted data used in load flow studies contain errors that affect the solution, as can be evidenced by running many cases perturbing the input data.

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 studies are an essential task carried out in power system planning and operations. However, the widely used deterministic load flow analysis is limited in their handling of network uncertainties or inaccuracies in input data. Therefore, probabilistic load flow (PLF) based on either numerical methods (such as Monte Carlo simulation) or an ...

The study of load tracing begins with gravity loads and a grid of horizontal elements. The primary elements are called girders, the secondary elements are called beams. Secondary implies that these members have a lower hierarchical standing, they rely on (connect to) the primary members which we call girders. The beams may be long, or they may be short.

Series load flow: A novel non-iterative load flow method
IEE Proceedings - Generation, Transmission and Distribution, 1998A 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.

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.
