Control of wind energy conversion systems based on the modular multilevel matrix converter
(IEEE Institute of Electrical and Electronics Engineers, 2017)
The nominal power of single wind energy conversion systems (WECS) has been steadily increasing, now reaching power ratings close to 10 MW. In the power conversion stage, medium-voltage power converters are replacing the ...
Resonant control system for low-voltage ride-through in wind energy conversion systems
(2016)
Owing to the high penetration of electrical energy from wind energy conversion systems (WECSs), some countries are enforcing stringent grid codes to regulate low-voltage-ride-through (LVRT) operation of WECSs. This study ...
Improved low-voltage-ride-through capability of fixed-speed wind turbines using decentralised control of STATCOM with energy storage system
(INST ENGINEERING TECHNOLOGY-IETHERTFORD, 2012)
The design and implementation of a new control scheme for reactive power compensation, voltage regulation and transient stability enhancement for wind turbines equipped with fixed-speed induction generators (IGs) in large ...
Estudo da capacidade LVRT de sistemas eólicos com DFIG durante a ocorrência de faltas elétricas
(Universidade Estadual Paulista (Unesp), 2020-06-01)
Nos últimos anos, questões relacionadas ao meio ambiente, principalmente, ao uso de combustíveis fósseis e à emissão de gases poluentes na atmosfera, ganharam grande destaque internacional. Com os avanços da comunidade ...
Resonant control system for low-voltage ride-through in wind energy conversion systems
(Inst Engineering Technology-IET, 2016)
Owing to the high penetration of electrical energy from wind energy conversion systems (WECSs), some countries are enforcing stringent grid codes to regulate low-voltage-ride-through (LVRT) operation of WECSs. This study ...
Predictive Control for Low-Voltage Ride-Through Enhancement of Three-Level-Boost and NPC-Converter-Based PMSG Wind Turbine
(2014)
In this paper, a predictive control scheme is proposed for the low-voltage ride-through (LVRT) enhancement of direct-driven permanent-magnet-synchronous-generator-based megawatt-level wind turbines. The proposed method ...
Robust STATCOM control for the stabilisation of fixed-speed wind turbines during low voltages
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
This paper presents a robust voltage control scheme for fixed-speed wind generators using a static synchronous compensator (STATCOM) controller. To enable a linear and robust control framework with structured uncertainty, ...
