Stability Analysis on Torsional Interactions of Turbine-Generator Connected With DFIG-WECS Using Admittance Model

IEEE Transactions on Power Systems, 2020
To evaluate the stability of Subsynchronous Torsional Interactions (SSTI), we propose a simple and effective approach using admittance model. The proposed approach gives the subsynchronous conductance based criterion to find the stability of torsional ...

Full-Scale WECs

2007
In this chapter, some of the concepts that have reached the full-scale stage are de-scribed in detail. Other examples could be given, but the analysis was limited to four main technologies: OWC (Oscillating Water Column), AWS (Archimedes Wave Swing), Pelamis and Wave Dragon presented in 7.1 to 7.4.

WEC STUDIES ON ENERGY FUTURE

Journal of Energy - Energija, 2022
The article gives a survey of studies made over the period 2005 to 2007 in coordination with and under the sponsorship of WEC. The studies deal with the energy sector with a long-term horizon up to 2050. Some studies are global in character, others are intended for the European region.

A simple approach to modelling and control of DFIG-based WECS in network reference frame

International Journal of Ambient Energy, 2020
The control design of grid interfaced Doubly-Fed Induction Generator (DFIG)-based Wind Energy Conversion Systems (WECS) requires the linear time-invariant model of DFIG-WECS in a common reference frame called a network reference frame.

Charts for economic evaluation of WECS

Solar & Wind Technology, 1988
Abstract This paper provides charts that can be used conveniently for quick assessment of economic feasibility of WECS under different sets of variables. These are: total capital cost (TCC), capacity factor (CF), wind turbine life time (N), operation and maintenance costs (OMC) and discount rate (DR).

Intelligent control of grid‐connected AC–DC–AC converters for a WECS based on T–S fuzzy interconnected systems modelling

IET Power Electronics, 2018
Control of power converters is undoubtedly an essential issue in wind-energy systems. This study focuses on the development of a control scheme dedicated to a wind-energy conversion system (WECS) based on Takagi–Sugeno (T–S) fuzzy model.
