Fault ride through augmentation of microgrid

2015 International Conference on Technological Advancements in Power and Energy (TAP Energy), 2015
The modern grid codes for fault ride through specifications in transmission and distribution grids specify that Distributed Generation (DG) must remain connected to the grid even at voltages well below the nominal voltage. This is contrary to the traditional approach, whereby the power plants were not required to stay connected.

Wind-Turbine Fault Ride-Through Enhancement

IEEE Transactions on Power Systems, 2005
Fault ride-through specifications listed in modern transmission and distribution grid codes specify that wind-turbine generators (WTGs) must remain connected to electricity networks at voltage levels well below nominal. Achieving reliable operation at greatly reduced voltage levels is proving problematic.

Fault Ride-Through Capability Enhancement by using Fuzzy Control

Power and Energy Systems, 2012
This paper proposes a fuzzy controller for improving Fault Ride-Through (FRT) capability of Doubly Fed Induction Generator (DFIG) based Wind Turbines (WTs). The controller is designed in order to compensate the voltage at the Point of Common Coupling (PCC) by regulating the reactive and active power generated by WTs simultaneously.

Fault Ride-through Testing of Wind Turbines

Wind Engineering, 2006
Grid codes concerning low-voltage fault ride-through capabilities of wind turbines are not (yet) harmonized, varying from country to country. Full-scale field testing of wind turbines with respect to all such codes may therefore not be practical. IEC 61400-21 is currently under revision, and the last committee draft (CD 2006) presents a standardized ...

Fault Ride-Through Criteria Development

2014
Wind energy integration into transmission systems has been accelerated by establishing robust grid codes relevant to the network. Fault Ride-Through (FRT) criteria is one of them, which requires generation to stay connected to transmission system under certain operational voltage envelope.

Wind-turbine fault ride-through enhancement

2006 IEEE Power Engineering Society General Meeting, 2006
Summary form only given. Fault ride-through specifications listed in modern transmission and distribution grid codes specify that wind-turbine generators (WTGs) must remain connected to electricity networks at voltage levels well below nominal. Achieving reliable operation at greatly reduced voltage levels is proving problematic.

Fault Ride Through and Fault Current Management for Microgrids

2020
Over the recent years, the distributed energy resource (DER) generation and integration with utility grid became the most widely used worldwide. Thereon, the integration of distributed energy resources to the power grid and their dynamics during grid faults had become a critical issue in the new grid code requirements. In line with this, the fault ride

Fault Ride Through Capability for Solar Inverters

EPE Journal, 2012
AbstractA solar inverter for utility scale has been developed in this paper, and the inverter has fault ride through (FRT) capability, which is now discussed in Japan and similar to requirement in U.S.A and Europe. This solar inverter consists of a boost chopper and a three-phase 2-level inverter, and the capacity covers from 20 kW to 600 kW.

Fault Ride-Through trip curves

2012 IEEE Power and Energy Society General Meeting, 2012
Over the past decade, new requirements have been proposed and implemented for Fault Ride Through, including a proposed NERC standard that would impose fault ride through requirements on all generation. Most existing fault ride through curves are used in the wind industry.

Fault ride-through capability of DFIG wind turbines

Renewable Energy, 2007
This paper concentrates on the fault ride-through capability of doubly fed induction generator (DFIG) wind turbines. The main attention in the paper is, therefore, drawn to the control of the DFIG wind turbine and of its power converter and to the ability to protect itself without disconnection during grid faults. The paper provides also an overview on
