In recent years there has been a great increase in the use of distributed generators.
Others see smart grids as the control of distributed generators connected to homes or to medium voltage networks.
The optimization technique utilized in this work to determine the placement of distributed generators is recent.
The penetration of gd(distributed generators) in distribution systems can cause different impacts in terms of system protection.
At the end, it was found that even with the input or output of distributed generators, distribution system continued to be protected.
This dissertation presents studies on the optimal allocation of fault indicators in distribution networks considering distributed generators.
The growing number of distributed generators connected to electricity distribution networks is a reality of electrical systems throughout the world.
Techniques such as topology reconfiguration, reconductoring, allocation of capacitors and distributed generators are usually proposed in technical studies.
Islanding occurs when one or more distributed generators feed a portion of the distribution system that becomes electrically isolated from the rest of the power system.
Consequently, fault current flows that were typically the contribution of substation may now be the contribution of distributed generators.
In this scenario,the widespread use of distributed generators connected near the loads shows the emergence of a new paradigm in electric energy production and application.
Islanding occurs when a part of the electrical system is supplied solely by a unit or group of distributed generators isolated from the main electrical network.
The connection of distributed generators to power subtransmission and distribution networks has been increasing recently due to the technical and economic benefits that such technology can provide.
From the perspective of the iep,the adopted model seeks to maximize the active power generation of distributed generators and minimize costs associated to this generation.
The purpose of this detection is to disconnect the distributed generators, segregating them from the system in case of loss of mains, avoiding that transmission and distribution lines remain energized by them.
This work proposes a new strategy to control the generated power in an alternating current autonomous microgrid that has distributed generators and battery banks.
Results obtained by an optimization technic for the maximum power injection from distributed generators were compared to those obtained by the methodology and differences were evaluated and discussed.
Fuel cells can operate as stationary electrical generators, potentially at significantly higher efficiencies than central power stations or other distributed generators.
The normative number 482, 2012, reduces bureaucracy in accessing micro andmini single phase distributed generators to the power grid, allowing residential consumers act as electric power generators elements.
Thus, distributed generators have to be equipped with anti-islanding protection schemes, because the islanded operation may put at risk the safety of people and the equipment. it can also deteriorate the power quality supplied to local consumers.
In this way, this work investigates fault location techniques for modern power distribution systems,characterized by the presence of distributed generators and monitoring infrastructure.
The vast changes in energy sectors,beginning from renewable energy sources to distributed generators and ending with micro-grids, call for new ideas and different ways of integrating the research in those fields and their application in the market.
In this dissertation, we present a detailed study of techniques for islanding detection of distribution systems in the presence of distributed generators in various forms of access and connection.
If disturbances occur in a power distribution systems in the presence of distributed generators(dgs), a common practice required by utilities is to disconnect such generators, aiming at avoiding a self-sustained energized island.
This work proposes a methodology based in the meta-heuristic tabu search to distribution power system restoration considering distributed generators installed on the system, using the encoding system node depth representation.
However, in order to evaluate if distributed generators benefit the operation of power networks, their technical impacts should be carefully studied, especially in distribution networks, which were originally designed to operate with unidirectional power flow.
Abstract Electric power distribution systems have been submitted to major changes related to the integration of new technologies such as distributed generators, electric vehicles, energy storage systems, smart meters, and digital protection equipment.
This paper presents a multi-objective modeling to optimize the number of generating units from distributed generators considering minimizing electrical losses on the network and also co2 emissions of distributed generators, considering renewable primary and non-renewable sources, as well as penetration of restrictions and maximum quantities generation units.
