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.

Anti-islanding today, successful islanding in the future

2010 63rd Annual Conference for Protective Relay Engineers, 2010
Distributed generation (DG) is gaining popularity in the United States and across the world. The Florida Public Service Commission recently passed rules encouraging the use of renewable resources. Integrating DG with the utility network poses challenges for anti-islanding schemes. These schemes detect islanding conditions and trip the DG. Fig.

Investigation on Voltage Sags Caused by DG Anti-Islanding Protection

IEEE Transactions on Power Delivery, 2013
This paper investigates the voltage sag caused by distributed generation anti-islanding protection. This is a new power-quality concern associated with distributed generation expansion. Anti-islanding protection aims to disconnect distributed generators immediately after the opening of a recloser.

Impact of RE's Anti‐Islanding on Power System Oscillatory Stability

Electrical Engineering in Japan, 2016
SUMMARYAlthough computer simulation is certainly a powerful tool for power system stability assessment, manual analysis is more helpful for understanding mechanism of unstable phenomena. Among unstable phenomena, oscillatory stability must be the most complex one.

Dispersed generation in MV networks: Performance of anti-islanding protections

Proceedings of 14th International Conference on Harmonics and Quality of Power - ICHQP 2010, 2010
The growing development of Dispersed Generation drives to a novel management of distribution networks in order to take advantages of this new form of generation. In particular the DG determines different power flows along distribution feeders modifying voltage profiles and fault levels and introducing new issues in protection systems.

Anti-islanding detector based on a robust PLL

2013 IEEE Energy Conversion Congress and Exposition, 2013
International Standards impose to Distributed Energy Resources, connected to the grid by an inverter, to detect an islanding condition within a suitable time interval. In this paper a Phase Locked Loop (PLL), based on a third-order prediction-correction filter, is proposed to implement an islanding detector with reduced detection time.

An Anti-islanding Protection for Inverters in Distributed Generation

IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018
This paper presents a new anti-islanding protection (AIP) scheme for inverters in integration of distributed generation (DG) sources into the grid. The main advantage of this proposed AIP scheme is that it can be embedded into the control of DG inverters without a need of additional part in the hardware of the inverter and any change in the controller.

Anti-islanding detection using Synchrophasors and Internet Protocol telecommunications

2011 2nd IEEE PES International Conference and Exhibition on Innovative Smart Grid Technologies, 2011
This paper presents a method of improving anti-islanding detection for distributed generation by application of a wide-area measurement system. Present anti-islanding solutions were developed when installed capacity of distributed generation was low. Issues such as nuisance tripping, cascade tripping and poor anti-islanding detection sensitivity common

A Novel Method for Anti-Islanding using Reactive Power

INTELEC 05 - Twenty-Seventh International Telecommunications Conference, 2005
Since the islanding of the PV generation systems can cause a loss of lives and damage to equipments, it has to be avoided by a reliable detection system. In this paper, a novel anti-islanding method is presented. The PV generation system applied to the proposed method maintains the real average output power components of the system by MPPT control ...

A combined method for anti-islanding in PV inverters

2016 13th International Conference on Power Electronics (CIEP), 2016
This paper presents a combined method to detect islanding conditions. The method combines two approaches in a two stage process, and is based on the injection of reactive current as a disturbance to detect islanding. In the first stage, the method tests the voltage rate of change and the frequency rate of change. Once an islanding situation is presumed
