Low-Voltage Ride-Through Remote Testing Method for Offshore Wind Turbines

IEEE Transactions on Instrumentation and Measurement, 2020
Grid-connected wind turbines (WTs) are required to have low-voltage ride-through (LVRT) capability. On-site LVRT test is a convincing certificating method. To tackle the limited accessibility and harsh conditions of on-site test for offshore WTs, this paper proposes a remote testing method, which places the testing device on shore to produce the ...

Low Voltage Ride-through of PV System Based on APFF

2018 2nd IEEE Conference on Energy Internet and Energy System Integration (EI2), 2018
Aiming at problems of two-stage photovoltaic(PV) grid-connected system including inverter overcurrent and large fluctuation of DC-side capacitor voltage when the grid voltage drops, a low voltage ride-through optimization control strategy based on active power feed forward(APFF) mode is proposed.

Low-voltage Ride-through Capability Characterization of Wind Farms

Electric Power Components and Systems, 2012
Abstract This article characterizes low-voltage ride-through capability of wind farms. Critical clearing time has been used in the literature as a measure of the transient stability of induction generators and, hence, an indication for low-voltage ride-through capability of single wind turbine generators.

Comparison of several Low Voltage Ride Through Attached Equipment

2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019
The power plant auxiliary drive system will work abnormally or even trip due to frequency converter voltage drops, which might be caused by transient state process of auxiliary power system or the external grid. Low voltage ride through (LVRT) is an effective way to solve the above problem.

The current control of PV inverter for low voltage ride through

2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012
The objective of this paper is to propose a maximum current amplitude control (MCAC) for the Photovoltaic (PV) power system with the low-voltage ride-through (LVRT) behaviour. The proposed MCAC strategy can generate the demanded active and reactive power depending on the output power condition of the PV array and the power rating of the grid-tied ...

Improving Microgrid Low-Voltage Ride-Through Capacity Using Neural Control

IEEE Systems Journal, 2020
In this article, a neural sliding-mode linearization controller is proposed to regulate the generated active and reactive power for each distributed energy resource in a microgrid. The developed controller is based on recurrent high-order neural network identification, trained online with an extended Kalman filter learning algorithm.

A rapid voltage detection method for low voltage ride through under distorted voltage conditions

2015 IEEE International Conference on Mechatronics and Automation (ICMA), 2015
This paper deals with a novel voltage detection method for low voltage ride through under distorted voltage conditions. According to the new Grid Codes, the photovoltaic (PV) system should keep connected with the grid and inject the acquired reactive power as soon as possible when the grid voltage sags.

Improvement low-voltage ride-through control of DFIG during grid faults

2014 International Conference on Multimedia Computing and Systems (ICMCS), 2014
This paper presents an improvement control to enhance Low-voltage Ride-through (LVRT) capability of a doubly fed induction generator (DFIG). The DFIG is very sensitive to grid fault. When voltage dip occurs, there are overvoltage and a transition of the current in rotor winding.

Low voltage ride through capability of fuel cell generation system connected to low voltage network

2011 IEEE Conference on Clean Energy and Technology (CET), 2011
New grid code is expected to require distributed generation units operating parallel with the low voltage grid to ride through low voltage event and at the same time injecting reactive current into the grid. The paper discusses and highlights the problems that could arise and explores the solutions to mitigate these problems.
