Abstract

Nowadays, the rising demand for electricity coupled with the lack of traditional forms of energy has become a global imperative. As a result, renewable energy is becoming a new development trend and is considered the best solution for electrical generation as well as environmental protection. Wind power takes the leading role with the fastest growth in renewable energy, promising to be a fundamental part of some national grids. However, there are many troubles for interconnection wind power to the main grid, especially many faults related to load flow and stability. The previous studies haven't concerned clearly the effects of different types of wind generators to actual grid integrated. In this paper, two types of wind generator including Fixed-Speed Induction Generators-FSIG and Doubly-fed induction generator -DFIG connected to Vietnam grid at Ninh Thuan province are studied in steady state as well as in Fault-Ride-Through. Fault assumptions in 2 cases steady-state and transient-stability. The results show that the DFIG could be more stable operation and faster recovery than FSIG due to its speed controller.

This paper investigates the design and analysis of a novel dual stator hybrid operational six-phase permanent magnet synchronous machine (NDSHOSP-PMSM) for wind power applications. This machine serves two purposes namely, motor and generator. The inner stator-rotor system operates as a yaw motor for the directional change of nacelle of the wind turbine system whereas the outer stator-rotor system operates as a high-power density and more reliable generating system. To further enhance the power density, reliability, and fault tolerance capability six-phase has been considered in both the stators. For the design and analysis of the proposed machine, the finite element method (FEM) has been opted as it is a more accurate method. The magnetostatic mode of analysis is taken for optimal design modeling, whereas for the performance analysis, the transient mode of analysis is chosen. The back electromotive force (EMF), %THD, torque-current, power-current, and torque-time characteristics are investigated for the inner stator-rotor system as a motor. Similarly, generated EMF, %THD, generated voltage-speed, terminal voltage-current, torque-time characteristic are investigated for the outer stator-rotor system as a generator.
... Furthermore, the DFIG based WTG system is sensitive to any grid disturbances which may lead to system instability at certain operating conditions [19]. Many control strategies [20,21] have been developed in literature to ensure high efficacy of the wind turbine system. A common control technique known as the PVdq control [1,16,17] is used in this paper. ...

In this paper we study the order reduction of a wind turbine model using the methods of balancing transformation and singular perturbations. We show that the order of the considered wind turbine model can be reduced from eight to six via the balancing transformation. Further reduction via the aforementioned method results in a significant jump in the error bound. In contrast, the method of singular perturbations shows that the order of the model can be further reduced to four, or two, and still provide very good approximations to the system model, in terms of its transient step response. Moreover, we show that the reduction in model order achieved via singular perturbations is superior to that achieved via balancing, when the linear-quadratic near-optimal controllers are considered and when wind turbulence and a large-signal disturbance are applied to the system.
... The power balance is one of the important factors to assess the impact of solar power plants when integrated into the grid in the steady state. Load flow analysis for the grid is in need to be clearly identified in order to provide appropriate operation solutions, ensure the stability of the power system as well as to minimize losses [9]. ...

Vietnam is a long coast country with high potential for wind energy development. However, the cost for wind farm project is a big challenge for the power system planning, while the location and capacity of the wind turbines have the large impact on the operation efficiency of the wind farm. Therefore, problem of optimal placement and size of wind farm attracts great interest of the practitioner and researchers. In this paper, the particle swarm optimization algorithm has been applied to optimize the placement and sizing of wind farm. The model has been tested on the simplified Vietnamese power system to determine the optimal location as well as installation capacity of the wind farm in order to minimize system operation cost while ensuring the capacity limit of transmission lines, power balance, and other constraints. The results in the paper can be applied for power system planning, design, and wind farm projects.

With increasing penetration of wind power into the power system, wind power participation in frequency regulation is regarded as a beneficial strategy to improve the dynamic frequency response characteristics of power systems. The traditional power system frequency response (SFR) model, which only includes synchronous generators, is no longer suitable for power systems with high penetrated wind power. An extended SFR model, based on the reduced-order model of wind turbine generator (WTG) and the traditional SFR model, is presented in this paper. In the extended SFR model, the reduced-order model of WTG with combined frequency control is deduced by employing small signal analysis theory. Afterwards, the stability analysis of a closed-loop control system for the extended SFR model is carried out. Time-domain simulations using a test system are performed to validate the effectiveness of the extended SFR model; this model can provide a simpler, clearer and faster way to analyze the dynamic frequency response characteristic for a high-wind integrated power systems. The impact of additional frequency control parameters and wind speed disturbances on the system dynamic frequency response characteristics are investigated.

The development of wind turbines (WT) and the capacities of wind power plants have increased significantly in the last years. Wind power plants (WPP) must provide the power quality required by new regulations and the reliability of the power system that is interconnected to. It is very important to analyze and understand the sources of disturbances that affect the power quality. In this paper is analyzed the performance of three different popular wind generators that are connected to the power system. Based on this analysis was made a comparison for the three wind turbines studied that are: the squirrel-cage induction generator (SCIG), the doubly-fed induction generator (DFIG), and the permanent-magnet synchronous generator (PMSG). The fixed speed system is more simple and reli-able, but severely limits the energy production of a wind turbine and power quality. In case of variable speed systems, comparisons shows that generator of similar rating can significantly enhance energy capture as well as power quality. More-over, performance of their output power leveling is validated by a new method nu-merically as maximum energy function and leveling function. The performances of these wind turbines and their characteristics are analysed in steady-state. Wind turbines systems are modeled in Matlab/Simulink environment. Simulation results matched well with the theoretical turbines operation.

This paper concentrates on the fault ride-through capability of doubly fed induction generator (DFIG) wind turbines. The main attention in the paper is, therefore, drawn to the control of the DFIG wind turbine and of its power converter and to the ability to protect itself without disconnection during grid faults. The paper provides also an overview on the interaction between variable-speed DFIG wind turbines and the power system subjected to disturbances, such as short circuit faults. The dynamic model of DFIG wind turbine includes models for both mechanical components as well as for all electrical components, controllers and for the protection device of DFIG necessary during grid faults. The viewpoint of the paper is to carry out different simulations to provide insight and understanding of the grid fault impact on both DFIG wind turbines and on the power system itself. The dynamic behaviour of DFIG wind turbines during grid faults is simulated and assessed by using a transmission power system generic model developed and delivered by the Danish Transmission System Operator Energinet.dk in the power system simulation toolbox PowerFactory DIgSILENT. The data for the wind turbines are not linked to a specific manufacturer, but are representative for the turbine and generator type used in variable-speed DFIG wind turbines with pitch control.

With rapid development of wind power technologies and significant growth of wind power capacity installed worldwide, various wind turbine concepts have been developed. The wind energy conversion system is demanded to be more cost-competitive, so that comparisons of different wind generator systems are necessary. An overview of different wind generator systems and their comparisons are presented. First, the contemporary wind turbines are classified with respect to both their control features and drive train types, and their strengths and weaknesses are described. The promising permanent magnet generator types are also investigated. Then, the quantitative comparison and market penetration of different wind generator systems are presented. Finally, the developing trends of wind generator systems and appropriate comparison criteria are discussed. It is shown that variable speed concepts with power electronics will continue to dominate and be very promising technologies for large wind farms. The future success of different wind turbine concepts may strongly depend on their ability of complying with both market expectations and the requirements of grid utility companies.
