The load flow study in a power system constitutes a study of paramount importance. The study reveals the electrical performance and power flows (real and reactive) for specified condition when the system is operating under steady state. This paper gives an overview of different techniques used for load flow study under different specified conditions. Keywords—Load Flow Studies, Y-matrix and Z-m...

The main focus of this paper is to presents comparative principal problems of bibliographies on the linearization of Load Flow equations, network outages and the interdependence among nodal power injections. These methods classified as simulation method, analytical method, or by a combination of both are used to obtain the mean and variance of Power Line Flow. Key-Words: Cumulative Distribution...

This paper shows an application of Artificial Network Technique for the analysis of load flow and determines the power system static states that is, bus voltages magnitudes and voltage angles of a balanced radial distribution system, without executing the power flow algorithm, for any given load. As the performance of the conventional load flow methods such as Fast decoupled load flow, Newton-R...

The present study is concerned with thin isotropic shallow shells interacting with inviscid fluid flow of constant velocity. It is assumed that the dynamic behaviour of the shells is governed by the Marguerre–von Kármán equations. The influence of the fluid flow is taken into account by introducing additional differential and external load terms in the shell equations. It is shown that the syst...

In a watershed, sediment arises due to the erosion and some factors such as pastures destruction,change users, no reasonable cultivation. That causes problems such as sedimentation in reservoirs andreduces their useful volume, reducing water quality in agricultural consumption; reduce the efficiencyof hydraulic structures and some other environmental problems. Changes in sediment load in a rive...

In a multi-regional interconnected grid, the probabilistic load flow (PLF) of any region cannot be calculated individually but should consider uncertainties introduced in other areas. Accordingly, topologies, loads, and generations every are needed. Although renewable generation data could assumed as publicly known, some regional independent system operators (ISOs) still would not share importa...

Probabilistic load flow (PLF) analyses the probability behaviour of the power injected and demanded in an electrical network, providing cumulative results of the power flowing through its lines. However, the probability behaviour analysis is not complete if the correlation between load demands has not been considered. Environmental or social factors can lead to such correlation. This paper prop...

A method has been developed for preparing load models for power flow and stability. The load modeling (LOADMOD) computer software transforms data on load class mix, composition, and characteristics into the from required for commonly–used power flow and transient stability simulation programs. Typical default data have been developed for load composition and characteristics. This paper defines ...
