Improving the Control Strategy of the DVR Compensator Based on an Adaptive Notch Filter with an Optimized PD Controller Using the IGWO Algorithm

International Transactions on Electrical Energy Systems, Volume 2024, Issue 1, 2024.
One of the objectives of electrical distribution networks is to provide customers with access to high‐quality electricity. Because any disruptions in these systems result in voltage disorders, different devices are employed to offset these disruptions on consumers who are more susceptible.

A novel FRT strategy for transformerless MMC to improve current differential protection performance under single-phase grounding faults

International Journal of Electrical Power & Energy Systems
AC/DC distribution networks are interconnected by converters such as modular multilevel converters (MMCs). In AC/DC distribution networks, single-phase grounding (SPG) faults can cause enormous challenges in relay protection.

Fault ride-through of renewable energy conversion systems during voltage recovery

Journal of Modern Power Systems and Clean Energy, 2016
Asymmetrical voltage swells during recovery of a short-circuit fault lead to fluctuations in the dc-link voltage of a renewable energy conversion system (RECS), and may induce reversed power flow and even trip the RECS. This paper studies characteristics

LVRT and HVRT control strategies of doubly- fed induction generator

, 2018
The Doubly Fed Induction Generator (DFIG) has a high sensitivity to the Grid Faults (GFs), which can cause many problems on the power quality and the production continuity. Actually, the grid connection requirements impose strict laws to respect to Low Voltage Ride Through (LVRT), High Voltage Ride Through (HVRT), and grid support capacities following ...

Voltage Support Capacity Improvement for Wind Farms with Reactive Power Substitution Control

CSEE Journal of Power and Energy Systems
Generally, voltage support at the point of common coupling (PCC) of a wind farm is achieved through centralized static var generators (SVGs). Since the reactive power requirements occupy their capacity in a steady state, the reactive power support ...

Modeling and simulation of HVRT and LVRT enhancement capability for doubly fed induction generator based wind energy conversion system

International Journal of Engineering & Technology, 2018
Generation of power using wind turbine is more across the globe, but a problem related using wind method of power generation is volt-age variation across the grid. The performance of wind turbine goes below the specified level during grid voltage variation. It might be due to overvoltage or under voltage condition.
