This paper presents a multi-objective formulation for optimal siting and sizing of distributed generation (DG) resources in distribution systems in order to minimize the cost of power losses and energy not supplied. The implemented technique is based on a genetic algorithm (GA) and weight method that employed to obtain the best compromise between these costs. Simulation results on 33-bus distri...

Original scientific paper Nowadays, the operational performance of the Distribution system can be improved by exchanging the functional links between the elements of the system, called reconfiguration. This paper aims at achieving such optimization through the reconfiguration of distribution systems taking into account various criteria. The newness of the method is in the fact that optimization...

in this paper, reconfiguration problem of distribution network has been investigated toimprove reliability and reduce power loss by placement of renewable energy sources; i.e. solarcell and wind turbine. for this, four reliability indices are considered in objective function;which are as follows: system average interruption frequency index (saifi), system averageinterruption duration index (sai...

This paper presents a new and useful methodology for simultaneous allocation of sectionalizer switches and distributed energy resources (DERs) considering both reliability and supply security aspects. The proposed algorithm defines the proper locations of sectionalizer switching devices in radial distribution networks considering the effect of DER units in the presented cost function and other ...

Article history: Received 8.5.2012. Received in revised form 16.7.2012. Accepted 20.7.2012. In medium voltage optimal power distribution network routing, especially in the suburban and rural ones, it is often necessary to estimate additional construction costs of tie feeders enabling backup supply in comparison with a decrease in energy not supplied costs. This paper describes one fast approxim...

One of the big concerns of big cities is facing with the increase of fossil fuel vehicles in the roads. The cars intensify greenhouse gas emission in civic centers. One approach to reduce the emission is replacing the cars by Plug-In Electric Vehicles (PEVs). In spite of reducing the emission, PEVs have some adverse effect on electric distribution networks. Technical challenges such as load and...

In this context, a novel structure has been proposed for simple Differential Evolutionary (DE) algorithm to solve optimal recloser placement. For this, an operator is added to DE algorithm to adapt concept of the problem. Other contribution of this work is formulating a novel objective function. The proposed objective function has been formulated to improve four reliability indices which consis...
