Distribution system planning is extremely important for the end consumers of electricity; it is indeed become necessity to explore the area of real term planning of distribution system. The practical planning of distribution system incorporates the selection of optimal conductor size selection and capacitor placement in radial distribution network in distribution system. The load flow needs to ...

An Enhanced genetic algorithm (EGA) which is used to the solution of the optimal load flow (OPF) with both continuous and discrete control variables. The tenuous control variables modeled are unit active power outputs and generator–bus voltage magnitudes while the discrete ones are transformer – tap settings and switchable shunt devices. A number of functional operating constraints, such as bra...

The combustion processes and emission formation in pre and main chambers of a Lister 8.1 IDI diesel are simulated with the Computational Fluid Dynamics (CFD) code. The model includes spray atomization, mixture formation and distribution and subsequently the combustion processes and emissions formation modeling are carried out with considering of flow configurations in two chambers. A part load ...

In this study, the planning problem concerned with simultaneous placement of distribution generation (DG) and capacitor bank in the distribution network is investigated from a local distribution company’s (DISCO’s) viewpoint based on minimum total cost over the planning period and applying genetic algorithm (GA). The cost terms of the objective function include risk cost of load not supplied of...

reliability evaluation of a large-scale composite power system faces to numerous events/outage and consequently imposes an extensive burden of calculations. in order to simplify the problem, determination of an equivalent system for large-scale power system is inevitable. this paper proposes a framework as reduction technique to separate a composite power system to three areas: external area, o...

This paper undertakes the problem of loss reduction in a radial distribution System. The objective is to determine the suitable size and location of the capacitors to be placed on a radial distribution system. The objective function is to increase of saving due to reduction of energy losses thereby taking into consideration cost of capacitor. In this part, load flow solution for the radial feed...

This paper reports a new and accurate method for load flow solution of radial distribution networks with minimum data preparation. The node and branch numbering need not to be sequential like other available methods. The proposed method does not need sending node, receiving node and branch numbers if these are sequential. The proposed method uses the simple equation to compute the voltage magni...

Abstract:Today, one of the important issues of power quality (PQ) in power systems is the current harmonics. Increasing expansion of nonlinear loads at different parts of the electric network makes harmonic distortion flow through the network. This causes the network to have background voltage and current harmonic distortion and even affect on the PQ of linear load performance. Therefore, it is...
