21__430_436.rar - The generating systems use Doubly-Fed Induction Generators (DFIGs) to achieve high conversion efficiency and to reduce the installation cost. This paper presents a modeling and Maximum Power Point Tracking (MPPT) control method of DFIG-based variable-speed wind energy conversion system. The generator considered is a wound rotor induction machine whose stator is connected directly to the grid and the rotor is fed through back-to-back Pulse-Width Modulation (PWM) converters. Stator flux-oriented vector control is applied to control the active and reactive current loops independently. The MPPT control method in a Wind Energy Conversion System (WECS) is proposed. The proposed control solution aims at driving the position of the operating point near to optimality. This is a very important aspect to maintain DFIGs efficiently in a variable wind speed. The wind generator is modeled in RSCAD program which is interfaced with the Real Time Digital Simulator (RTDS).

Control-of-Multi-terminal-VSC-HVDC.zip - Given these two interests for HVDC in the Norwegian offshore, the use of Multiterminal HVDC (MTDC) is a potential solution for the integration of the wind farms and oil/gas platforms into the onshore grid. Control systems for multiterminal HVDC (MTDC) networks should be developed and their operation be analyzed. First controllers for two-terminal HVDC connected to different types of AC grids must be developed and analyzed. Then this must be extended to develop control of multiterminal HVDC system. Models should be developed in PSCAD/EMTDC simulation software and results should be analyzed to validated proposed control schemes.
