This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regional reliability organizations require power plants to validate the dynamic models that represent them to ensure that power systems studies are performed to the best representation of the components installed. In the process of validating a wind power plant (WPP), one must be cognizant of the parameter settings of the wind turbine generators (WTGs) and the operational settings of the WPP. Validating the dynamic model of a WPP is required to be performed periodically. This is because the control parameters of the WTGs and the other supporting components within a WPP may be modified to comply with new grid codes or upgrades to the WTG controller with new capabilities developed by the turbine manufacturers or requested by the plant owners or operators. The diversity within a WPP affects the way we represent it in a model. Diversity within a WPP may be found in the way the WTGs are controlled, the wind resource, the layout of the WPP (electrical diversity), and the type of WTGs used. Each group of WTGs constitutes a significant portion of the output power of the WPP, and their unique and salient behaviors should be represented individually. The objective of this paper is to illustrate the process of dynamic model validations of WTGs and WPPs, the available data recorded that must be screened before it is used for the dynamic validations, and the assumptions made in the dynamic models of the WTG and WPP that must be understood. Without understanding the correct process, the validations may lead to the wrong representations of the WTG and WPP modeled.

Available in PDF, EPUB and Kindle. Book excerpt: The use of proprietary models to represent installed wind power plants is incompatible with critical grid planning activities that are conducted by regional reliability organizations as a collaborative effort among many stakeholders. In this context, the use of generic or simplified models is desirable. To address this industry need, the Western Electricity Coordinating Council (WECC) has embarked on the development of generic positive sequence WTG models for large-scale power system transient stability analysis. As an integral part of this WECC activity, the National Renewable Energy Laboratory (NREL) is engaged in a model validation effort. This paper discusses the process of model validation against field measurements.

Available in PDF, EPUB and Kindle. Book excerpt: Wind Power Plant (WPP) and Wind Turbine (WT) modeling are becoming of key importance due to the relevant wind-generation impact on power systems. Wind integration into power systems must be carefully analyzed to forecast the effects on grid stability and reliability. Different agents, such as Transmission System Operators (TSOs) and Distribution System Operators (DSOs), focus on transient analyses. Wind turbine manufacturers, power system software developers, and technical consultants are also involved. WPP and WT dynamic models are often divided into two types: detailed and simplified. Detailed models are used for Electro-Magnetic Transient (EMT) simulations, providing both electrical and mechanical responses with high accuracy during short time intervals. Simplified models, also known as standard or generic models, are designed to give reliable responses, avoiding high computational resources. Simplified models are commonly used by TSOs and DSOs to carry out different transient stability studies, including loss of generation, switching of power lines or balanced faults, etc., Assessment and validation of such dynamic models is also a major issue due to the importance and difficulty of collecting real data. Solutions facing all these challenges, including the development, validation and application of WT and WPP models are presented in this Issue.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this paper is to present test cases for wind turbine generator and wind power plant models commonly used during commissioning of wind power plants to ensure grid integration compatibility. In this paper, different types of wind power plant models based on the Western Electricity Coordinating Council Wind Generator Modeling Group's standardization efforts are implemented on a real-time digital simulator, and different test cases are used to gauge their grid integration capability. The low-voltage ride through and reactive power support capability and limitations of wind turbine generators under different grid conditions are explored. Several types of transient events (e.g., symmetrical and unsymmetrical faults, frequency dips) are included in the test cases. The differences in responses from different types of wind turbine are discussed in detail.

Book excerpt: The development of representative wind turbine models is important to assess realistic impacts of large penetration of wind energy on power systems. During the past decade, several computer models representing different types of wind turbine have become available. One issue is that these models have not been standardised amongst manufacturers. The existing ambiguities in the modelling of wind turbine generators and their effects on simulation results have to be studied in detail. The main goal of this thesis is concerned with the understanding, modelling and grid impacts of large wind farms containing a great number of wind turbines in a power transmission network. In particular, generic models of the doubly-fed induction generator (DFIG) are developed for time-domain simulations and are implemented in the standard power system simulation software DIgSILENT PowerFactory. The results show that the developed models are able to simulate DFIG responses with sufficient accuracy. Response accuracy of the developed models is validated against detailed models and, in some cases, against field measurement data. Different influencing factors of dynamic reactive power compensation are also investigated. It is found that the fault ride-through capability of a wind farm can be generally improved by a mix of static and dynamic reactive compensation systems. A new aggregation approach based on generator speed deviation is also proposed. The results reveal that better performance is achieved by the multi-machine equivalents than the single machine model. The single machine model fails to account for the dynamic response of wind turbines when there is a sudden disconnection of wind generator units during grid disturbances. The proposed technique could have value for representing large wind farms on a consistent basis. The short-circuit models using symmetrical components are developed for DFIG-based wind farms. These models are useful for the system operator to determine whether the wind farm meets the requirements of recently proposed grid codes. The impact of the model-related difference on basic protection requirements of DFIG are further investigated. Finally, an important contribution on model validation using naturally occurring power system disturbances is demonstrated. It is found that the generic models in their present form are capable of capturing the main dynamic responses and control features of the wind generators. It is also observed that the specific control/protection functions of the detailed models require additional verification if these models are to be used for actual wind integration studies.

Book excerpt: IEC 61400-27 defines standard electrical simulation models for wind turbines and wind power plants. The specified models are time domain positive sequence simulation models, intended to be used in power system and grid stability analyses. The models are applicable for dynamic simulations of short term stability in power systems. IEC 61400-27 includes procedures for validation of the specified electrical simulation models. The validation procedure for IEC 61400-27 is based on tests specified in IEC 61400-21. IEC 61400-27 consists of two parts with the following scope: IEC 61400-27-1 specifies dynamic simulation models for generic wind turbine topologies/ concepts / configurations on the market. IEC 61400-27-1 defines the generic terms and parameters with the purpose of specifying the electrical characteristics of a wind turbine at the connection terminals. The models are described in a modular way which can be applied for future wind turbine concepts. The dynamic simulation models refer to the wind turbine terminals. The validation procedure specified in IEC 61400-27-1 focuses on the IEC 61400-21 tests for response to voltage dips, reference point changes and grid protection. IEC 61400-27-2 specifies dynamic simulation models for the generic wind power plant topologies / configurations on the market including wind power plant control and auxiliary equipment. In addition IEC 61400-27-2 specifies a method to create models for future wind power plant configurations. The wind power plant models are based on the wind turbine models specified in IEC 61400-27-1. The electrical simulation models specified in IEC 61400-27 are independent of any software simulation tool.

This book was released on 2010 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: "With the growing energy demand and need to decrease greenhouse gas emissions there has been a rise in the popularity of renewable energy systems. One of the most popular renewable energy systems over the past decade has been the wind turbine. Technological advances in modeling, prediction, sensing and control combined with the current shift towards decentralized power have prompted development of wind energy systems. Decentralized distribution allows for lower transmission losses because of the closer proximity to the consumer and greater regional control. The wind turbine has positioned itself as the leading energy system to serve as a cornerstone in the development of decentralized energy distribution. This research focuses on the development of a nonlinear dynamic model of a variable speed wind turbine. The modeling effort is followed by model validation against published data. Subsequently, benchmark control problems and existing control strategies are reviewed from literature. Emphasis is placed on variable speed form of operation. Control strategies are studied for two different operating modes of a wind turbine, namely operations below and above the rated-speed. For the former case control design is based on power maximization and for the latter the control design is based on power regulation. For each case, standard control strategies appearing in literature for individual operating regimes are implemented, and thereafter focus is placed on robust performance. Subsequently attempts are made to design new and/or improved strategies. The new control strategies proposed in this research are based on principles from nonlinear control. Furthermore, the research attempts to apply certain relatively new techniques such as extremum-seeking-control to the wind-turbine application. Finally, the research proposes a switching method to combine the control strategies for individual operating regimes."--Abstract.
