In this paper, the combined and new methods in distribution network with distributed generation are introduced to allocate fixed cost fairly that is applicable for radial network. Allocation of fixed cost based MW-mile is not fairer method. Fixed cost allocated based on average or peak consumed power using MW-mile that is not fairer method. It is essential to a new method introduced. Unfair pri...

Events with low probability and high impact, which annually cause high damages, seriously threaten the health of the distribution networks. Hence, more attention to the issue of enhancing network resilience and continuity of power supply, feels more than ever, all over the world. In modern distribution networks, because of the increasing presence of distributed generation resources, an alternat...

The microgrid concept provides attractive solutions for reliability enhancement of power distribution systems. Normally, microgrids contain renewable-energy-based Distributed Generation (DG) units, which their output power varies with different environmental conditions. In addition, load demand usually changes with factors such as hourly and seasonal customer activities. Hence, these issues hav...

In this paper, an improved impedance based method has been proposed for fault location in power distribution network with presence of photovoltaic distributed generation resources. Within this method, current and voltage are measured at the beginning of feeder and at the location of distributed generation resources. The π line model is used for improving the accuracy of the suggested method....

The increasing development of the use of new energies has led to the widespread use of power electronics, so that electronic power converters play an important role in extracting power from renewable sources. Power electronics can convert raw energy produced from new energy into the desired power with controlled current, voltage and frequency to be used in the power grid. Restructuring of power...
