The proliferation of nonlinear electronic loads is increasing day by day, and it can anticipate an influx of newer technologies in this domain in the future. This article focuses on the impacts of various home nonlinear electric equipment on the power quality of electrical distribution system. It was studied the influence of operating mode on the harmonic pollution generated by nonlinear home a...

In most power system studies, a major part of the problem is the finding of the voltages needed to meet a given schedule of loads and generation. Until now, iteration methods have been used to calculate the respective load flows. This paper presents a study to compare Newton method and sparse matrices with artificial neural networks regarding a load flow problem in electric distribution lines. ...

Methods to solve natural gas loadflow problems using electric loadflow techniques are presented. The motivation is to integrate a natural gas network with an electric power transmission network so that the network analysis for a combined natural gas and electric power distribution network can be performed in a consistent manner. The issues arising from solving gas loadflow problems are discusse...

In this paper, we develop a modeling and computational framework that allows for the determination of optimal carbon taxes applied to electric power plants in the context of electric power supply chain (generation/distribution/consumption) networks. The adoption of carbon/pollution taxes both internationally and regionally has been fueled by global climate change and fuel security risks with a ...

South Africa’s Government policy embraces the inclusion of distributed energy resources (DER), namely: renewable energy generation, embedded generation (EG) or distributed generation (DG) in the future national generation mix. The renewable energy program incorporates wind power, concentrated solar power (CSP), solar photo-voltaic (PV), landfill, and mini/micro hydro, and envisages a total of 1...

Regarding the nature of non-linear discrete placement, and in order to determine the optimal capacity of the substation, the goal in the present study will be a number of local optimum points. In this research, the problem of optimal placement posts to reduce power losses by considering Distributed Generation (DG). In formulating the objective function, geographical distribution density in the ...
