With an ever-increasing importance of wind power generation in power systems, the necessity of choosing the appropriate type of technology for the wind turbine generators becomes more significant. In the current paper, fixed and variable speed wind turbines and the application of energy storage system (ESS) to smoothen the wind farm output power are studied. A detailed analysis of the influence of...
Using bulk energy storage systems such as pumped-hydro electric storage (PHES) and compressed-air energy storage (CAES) with wind power plants offers advantages. They are well-proven technologies and more economical compared to batteries. Being synchronous machines, apart from the ability to regulate wind farm real power output, they can also be used to provide reactive power to support wind farms,...
This paper describes the effect of electrical parameters of the double fed induction generator on the transient voltage stability of a DFIG to a simple grid; the DFIG model has been developed in the Matlab/simulink tool. The dynamic behavior of a wind turbine connected to a grid is examined. A three-phase fault is applied close to the wind turbine. The effect of different electrical parameters of...
It is expected that increasing amount of distributed generation (DG) will be connected to electrical power systems in the near future. When these generations are in small amounts, their impacts on power system dynamics will be negligible. But if the penetration level becomes higher, distributed generations may start to influence the dynamic behavior of a power system as a whole and its impacts is...
This article is concerned with the impact of large-scale wind farms utilizing double fed induction generator (DFIG) on the transient stability to a general power system. In the first instance, the synthetical dynamic model of the wind turbine generators (WTGs) is introduced, including pitch angle control model and the generator protective model. And then, the simulation is made to the CIGRE B4-39...
During recent years, the size of individual wind turbines has grown closer to 10 MW, and the size of wind power plants has increased significantly to 300 MW or more. This growing size of wind power generation requires that careful evaluation of transient stability of the overall grid should be undertaken. This paper attempts to investigate the impact of wind power plant penetration on the transient...
This paper, presents a pitch controlled Wind Turbine Generation System (WTGS) which is used in practice now a days, to have optimum power flow and to reduce overloading of wind turbine when higher wind speeds are available. Also, a pitch control system is used for stabilization of the wind turbine at grid faults. Application of Static Synchronous Compensator (STATCOM) and static capacitor bank is...
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...
This paper presents the response of distribution static synchronous compensator (DSTATCOM). The connection of wind turbines to distribution systems may affect the voltage quality offered to the consumers. One of the factors contributing to this effect is the rapid variations of the wind turbine output power, which cause respective fluctuations in the supply voltage referred to as flicker. This paper...
This work presents firstly a description of simulation models for use in PowerFactoryTM and ATP programs for transient stability studies of power systems with wind turbines. Based on these models, simulation modules for both platforms were developed, the objective is to allow an evaluation comparing a digital simulator of transients with free distribution, ATP, with a reference program internationally...
