Intelligent anti-islanding protection scheme for distributed generations

2013 Annual IEEE India Conference (INDICON), 2013
The paper presents a passive islanding detection scheme for both synchronous and inverter based distributed generations interfaced to microgrid using Decision Tree. The scheme involves extraction of different features at target DG location and builds the Decision Tree for intelligent anti-islanding protection.

An Autoground System for Anti-Islanding Protection of Distributed Generation

IEEE Transactions on Power Systems, 2014
Due to the variety of distribution generation (DG) sizes and technologies connecting to distribution networks, and the concerns associated with out-of phase reclosing, anti-islanding continues to be an issue where no clear solution exists. This paper presents an autoground approach that was proposed in the context of an IEEE working group on best ...

Autonomous microgrid operation subsequent to an anti-islanding scheme

Sustainable Cities and Society, 2018
Abstract A microgrid is a scaled-down power grid, comprising of distributed power generations (DPGs) and loads. It generally operates in conjunction with the utility grid, but can also isolate to operate in “islanded mode” and serve independently according to the physical and/or economic circumstances.

A combined active anti-islanding method for photovoltaic systems

Renewable Energy, 2008
In a modern power system, photovoltaic as distributed generated source is growing larger and it can cause a variety of problems. The most important problem is that of the islanding phenomenon. In order to prevent islanding phenomenon, three kinds of active islanding detection methods have been studied.

Synchrophasor based transmission system anti-islanding scheme

2017 IEEE Power & Energy Society General Meeting, 2017
Unintended power system islanding means a portion of loads and generators become isolated from the rest of the grid. The islanded area is susceptible to severe power quality problems and may come across system instability. Islanding may occur in both distribution and transmission grids.

Assessing solar PV inverters' anti-islanding protection

2014 IEEE 40th Photovoltaic Specialist Conference (PVSC), 2014
This paper provides an overview of the islanding potential of solar photovoltaic (PV) inverters. Solar PV inverters are typically known to have very effective protection mechanisms, but concerns have been raised as to whether or not they could maintain an island if load and generation were closely matched and/or if there were additional sources of ...

Testing of anti-islanding protections for grid-connected inverters

2007 International Conference on Clean Electrical Power, 2007
Nowadays, almost all photovoltaic and grid-connected inverters, have internal protections against islanding. Usually, these protections perform a disconnection from the grid when process variables go beyond over-voltage or under-voltage thresholds, as well as over-frequency or under-frequency thresholds.

Implementation of Anti-islanding Scheme for a Grid Connected Inverter

2014
As more PV systems join the utility grid the concern of undetected islanding operation increases. This concern is due to the safety hazards this phenomenon imposes on personnel and equipment. This paper discusses there different islanding schemes used and their features.

Modeling anti-islanding protection devices for photovoltaic systems

Renewable Energy, 2004
Abstract Applications of grid-connected photovoltaic systems are rapidly expanding, providing a viable technology for renewable energy resources. Such systems are utility interactive and one of the major difficulties in their efficient use is related to islanding phenomena connected with a possibility of supplying surplus power back to the utility ...
