According to the growth of power generated by wind farms and the increased number of non-linear loads, providing a high quality electrical power, should be considered. This paper is addressed the issue of application and analysis of a Dynamic Voltage Restorer (DVR) to enhance the quality of power flows in a stand-alone microgrid, including wind energy conversion systems and the sensitive loads. The...
A novel control method for tip speed ratios of the series connected wind turbines in a wind farm by controlling the field currents of the wind generators is proposed. It is confirmed that good agreements between experimental and simulation results are obtained, showing the usefulness of the proposed method of the simulation model. Also, it is shown that reactive power of the wind generators of this...
This paper investigates the effect of connecting FACTS (Flexible AC Transmission System) device such as a STATCOM (Static Synchronous Compensator) to the point of common coupling (PCC) of a wind farm composed of DFIG. Simulation results show that a FACTS device can effectively enhance the performance of the DFIG, when it is disconnected by the crowbar switch during grid fault by providing additional...
A research on differences of latest Grid Code requirements for wind farm integration between China and selected EU countries are conducted. The similarities and differences of these Grid Codes in the aspects of active power/frequency control, reactive power/voltage control and fault ride-through capability are compared. The main causes of these differences are investigated and the author tried to...
Growing of wind power has resulted in a need for evaluation of its impact on power systems planning and operation. This paper analyzes the benefits of regulating wind power for power systems. A new unified index will be introduced to comprehensively evaluate the performance of the system with wind power at different possible locations, considering not only the benefits of loss reduction and voltage...
Wind energy has taken off into a new peak in terms of its popularity among other new generation technologies. The socio-economic and environmental benefits impact the general population. A low cost of energy along with grid compatibility can be achieved due to mass production technology, power electronics advancement, and intelligent controllability. This paper attempts to shed the light on many aspects...
Traditional definitions of power quantities presented in the IEEE Standard 1459-2000 are compatible only with stationary waveforms, however for non-stationary waveforms, the wavelet-based approach has been shown to be more suitable. This paper develops a new wavelet packet transform (WPT) based approach for measuring the recommended power quantities in the IEEE Standard. The reformulated quantities...
Wind energy will continue to grow at a rapid pace and will provide an increasingly large portion of the total electricity generation. To achieve its full potential, the industry needs adequate wind-turbine generator (WTG) dynamic models to determine the impact of adding wind generation, and establish how the system needs to be upgraded.For the most part, WTG manufacturers have sponsored the development...
As the size and number of wind power plants (WPP) increases, power system planners will need to study their impact on the power system in more detail. As the level of wind power penetration into the grid increases, the transmission system integration requirements will become more critical [1-2]. A very large WPP may contain hundreds of megawatt-size wind turbines. These turbines are interconnected...
Wind power exploitation development to provide Electricity has had more acceleration in recent years in compare with other sources of providing electrical energy in the world. Since, regions with the potential of wind energy are not necessarily close to consumers, analyzing and modeling of wind farms in order to distribute system load and to study the electrical and mechanical changes of them is important...
