World’s energy needs have encouraged the development of wind power sources. An increasing number of wind farms are being connected to the power grid and accurate the development of wind farm models need to be developed to study the dynamic behavior of them. This paper reports an investigation to compare two different modeling approaches of a real wind farm. This study is applied to the dynamic model...
This paper concerns with exploitation of renewable energy sources for meeting energy requirements of remote locations. It presents an investigation which is based on a practical project that was executed in collaboration between academia and industry. It involves design and installation of a prototype integrated renewable energy system which consists of two 15 kW wind turbines, electrolyser, fuel...
This paper presents development of an adaptive rule-based fault identification and phase selection technique for maintaining continued operation of distributed generators (DGs) during single-line-to-ground (SLG) fault condition. The emphasis in this paper will be placed on digital data processing and testing of the proposed rule-based fault identification and phase selection technique. The whole process...
This paper presents the development of an adaptive rule based fault identification and phase selection technique to be used in the implementation of single phase auto-reclosing (SPAR) in power distribution network with distributed generators (DGs). The proposed method uses only the three line currents measured at the relay point. The waveform pattern of phase angle and symmetrical components of the...
This paper presents the results obtained from a PSCAD/EMTDC dynamic fault simulation of a grid connected Doubly-fed Induction Generator (DFIG). The transient stability performance of the DFIG is investigated; case studies which demonstrate the possibility of wind turbine generator torsional vibration, and the concept of Critical Clearing Time (CCT) for the DFIG are presented and the results are compared...
The dynamic interaction of a Distributed Synchronous Generator (DSG) with Fixed-speed (FSIG) and Doubly-Fed induction generator (DFIG)-based wind turbines during network fault conditions is presented in this paper. The objective is to enhance the damping of the wind turbine torsional oscillations, and the transient stability margin of the distributed generators measured by their respective Critical...
Generation of electricity using wind power has received considerable attention worldwide in recent years. In order to investigate the impacts of the integration of wind farm into utilities' network various windmill models have been developed. One such impact is related to the critical clearing time (CCT) of the wind power based embedded generators (WPBEG). The work in this paper has shown that oversimplification...
