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 ...
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 ...
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 ...
Modelling, Simulation and Fuzzy Self-Tuning Control of D-STATCOM in a Single Machine Infinite Bus Power System
(2019-01-10)
In recent years, demand for electricity has increased considerably, while the expansion of generation and transmission has been very slow due to limited investment in resources and environmental restrictions. Methods: As ...
