Comparative study of back-stepping controller and super twisting sliding mode controller for indirect power control of wind generator
(2019-12-01)
This paper presents the application nonlinear control to regulate the rotor currents and control the active and reactive powers generated by the Doubly Fed Induction Generator used in the Wind Energy Conversion System ...
New Hybrid Sensorless Speed of a Non-Salient Pole PMSG Coupled to Wind turbine Using a Modified Switching Algorithm
(2019-11-01)
The paper focuses on the design of position and speed observers for the rotor of a non-salient pole permanent magnet synchronous generator (NSPPMSG) coupled to a wind turbine. With the random nature of wind speed this ...

Demand-Response Based Energy Advisor for Household Energy Management
(2019-07-31)
Home energy management systems (HEMS) are set to play a key role in the future smart grid (SG). HEMS concept enables residential customers to actively participate in demand response programs (DR) to control their energy ...
Imposed Switching Frequency Direct Torque Control of Induction Machine Using Five Level Flying Capacitors Inverter
(2019-06-30)
The paper proposes a new control structure for sensorless induction motor drive based on a five-level voltage source inverter (VSI). The output voltages of the five-level VSI can be represented by nine groups. Then, the ...
A Robust Power Control Strategy to Enhance LVRT Capability of Grid-Connected DFIG-Based Wind Energy Systems
(2019-06-01)
This paper presents a new robust and effective control strategy to mitigate symmetrical voltage dips in a grid-connected doubly-fed induction generator (DFIG) wind energy conversion system without any additional hardware ...
Robustification du contrôle des éoliennes pour une meilleure intégration dans un réseau déséquilibré
(Institute of Electrical and Electronics Engineers (IEEE), 2019-05-13)
Le but de cet article est de montrer l’intérêt de la robustification du contrôle de la Génératrice Asynchrone à Double Alimentation (GADA) lors de déséquilibre des tensions du réseau. L’objectif est d’améliorer les ...
Enhanced Electric Vehicle Integration in the UK Low Voltage Networks with Distributed Phase Shifting Control
(2019-04-09)
Electric vehicles (EV) have gained global attention due to increasing oil prices and rising concerns about transportation-related urban air pollution and climate change. While mass adoption of EVs has several economic and ...
The transition towards a sustainable energy system in Europe: What role can North Africa's solar resources play?
(2019-04-01)
Securing energy supply and speeding up the transition towards a reliable, sustainable, low-carbon energy system are among the major current and future challenges facing Europe. Importing dispatchable solar electricity from ...
Power system security enhancement by HVDC links using a closed-loop emergency control
(2019-03-01)
In recent years, guaranteeing that large-scale interconnected systems operate safely, stably and economically has become a major and emergency issue. A number of high profile blackouts caused by cascading outages have ...
