This paper presents the state space modelling of doubly fed induction generator (DFIG) for small signal stability assessment. The gains of PI controller in torque and voltage control loop of rotor-side converter (RSC) are optimized by particle swarm optimization (PSO) to improve the dynamic performance of DFIG. These optimized parameters results in improved damping of DFIG and minimizes the osc...

Title: Effects of high and low velocity muscle contraction on myosin heavy chain mRNA and protein expression in conjunction with muscle performance in the elderly Introduction: Aging decreases skeletal muscle mass and contractile ability. This decreases the capacity for an individual to successfully carry out activities of daily living, eventually leading to physical disability. Recent research...

This paper presents a coordinated control strategy for a hybrid wind farm with doubly-fed induction generator (DFIG)and direct-driven permanent-magnet synchronous generator (PMSG)-based wind turbines under symmetrical grid faults. The proposed low-voltage ride-through (LVRT) strategy is based on a novel current allocation principle and is implemented for individual DFIGor PMSG-based wind turbin...

The Voltage Source Converter-HVDC (VSC-HVDC) system applied to wind power generation can solve large scale wind farm grid-connection and long distance transmission problems. However, the low voltage ride through (LVRT) of the VSC-HVDC connected wind farm is a key technology issue that must be solved, and it is currently lacking an economic and effective solution. In this paper, a LVRT coordinat...

This paper suggest a control strategy to enhance the LVRT capability of doubly fed induction generator (DFIG) based wind turbine system using dynamic voltage restorer (DVR). Wind should support grid during fault time. The method used here is series compensation at point common coupling on occurrence maintain stator constant. performance improved by optimization PI parameters particle swarm as c...

The article presented here utilizes the particle swarm optimization (PSO) and water cycle algorithm (WCA) based dynamic voltage restorer (DVR) to augment low ride through (LVRT) performance of a hybrid renewable energy system (HRES). Moreover, FACT equipment like is deployed boost quick responsiveness compensation good transient HRES. Due numerous disturbances brought on by WECS' nonlinearity, ...
