Book Description
This book focuses on two of the most important aspects of wind farm operation: decisions and control. The first part of the book deals with decision-making processes, and explains that hybrid wind farm operation is governed by a set of alternatives that the wind farm operator must choose from in order to achieve optimal delivery of wind power to the utility grid. This decision-making is accompanied by accurate forecasts of wind speed, which must be known beforehand. Errors in wind forecasting can be compensated for by pumping power from a reserve capacity to the grid using a battery energy storage system (BESS). Alternatives based on penalty cost are assessed using certain criteria, and MCDM methods are used to evaluate the best choice. Further, considering the randomness in the dynamic phenomenon in wind farms, a fuzzy MCDM approach is applied during the decision-making process to evaluate the best alternative for hybrid wind farm operation. Case studies from wind farms in the USA are presented, together with numerical solutions to the problem. In turn, the second part deals with the control aspect, and especially with yaw angle control, which facilitates power maximization at wind farms. A novel transfer function-based methodology is presented that controls the wake center of the upstream turbine(s); lidar-based numerical simulation is carried out for wind farm layouts; and an adaptive control strategy is implemented to achieve the desired yaw angle for upstream turbines. The proposed methodology is tested for two wind farm layouts. Wake management is also implemented for hybrid wind farms where BESS life enhancement is studied. The effect of yaw angle on the operational cost of BESS is assessed, and case studies for wind farm datasets from the USA and Denmark are discussed. Overall, the book provides a comprehensive guide to decision and control aspects for hybrid wind farms, which are particularly important from an industrial standpoint.

Book Description
Wind energy systems are central contributors to renewable energy generation, and their technology is continuously improved and updated. Without losing sight of theory, Control of Large Wind Energy Systems demonstrates how to implement concrete control systems for modern wind turbines, explaining the reasons behind choices and decisions. This book provides an extended treatment of different control topics divided into three thematic parts including modelling, control and implementation. Solutions for real-life difficulties such as multi-parameter tuning of several controllers, curve fitting of nonlinear power curves, and filter design for concrete signals are also undertaken. Examples and a case study are included to illustrate the parametrization of models, the control systems design with problems and possible solutions. Advice for the selection of control laws, calculation of specific parameters, which are necessary for the control laws, as the sensitivity functions, is given, as well as an evaluation of control performance based on indices and load calculation. Control of Large Wind Energy Systems covers methodologies which are not usually found in literature on this topic, including fractional order PID and nonlinear PID for pitch control, peak shaving control and extremum seeking control for the generator control, yaw control and shutdown control. This makes it an ideal book for postgraduate students, researchers and industrial engineers in the field of wind turbine control. Advances in Industrial Control reports and encourages the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for researchers to present an extended exposition of new work in all aspects of industrial control.

Book Description
The goals of this research are to improve the current treatment of wind farms in large-scale models via a new hybrid wind farm parameterization to better understand the potential impacts of offshore wind farms on the environment. ☐ Wind turbines extract energy from the atmosphere and the resulting wakes affect the boundary layer and the environment. The approach chosen in this dissertation to study these impacts of wind turbines is numerical simulations utilizing the weather prediction model called Weather Research and Forecast (WRF), in which wind farms are currently parameterized as simple elevated sinks of kinetic energy and sources of turbulent kinetic energy (TKE). A well-developed wind farm parameterization is essential to better understand the potential impacts of wind farms on weather and climate at the regional to global scales. ☐ The first part of this dissertation is therefore a case study to understand the impacts of hypothetical, large, offshore wind farms on local meteorology, especially the precipitation, employing the current two most widely used wind farm parameterizations. This study quantitatively tests whether the offshore turbines may affect precipitation patterns during Hurricane Harvey, since Hurricane Harvey brought to the Texas coast possibly the heaviest rain ever recorded in U.S. history, which then caused flooding at unprecedented levels. Model results indicate that the offshore wind farms have a strong impact on the distribution of accumulated precipitation, with an obvious decrease onshore, downstream of the wind farms, and an increase in the offshore areas, upstream of or within the wind farms. The accumulated precipitation during Harvey was reduced by up to 21% in the presence of offshore wind farms consisting of hundreds of thousands of turbines. Compared with the control case with no wind turbines, increased horizontal wind divergence and lower vertical velocity are found where the precipitation is reduced onshore, whereas increased horizontal wind convergence and higher vertical velocity occur upstream or within the offshore wind farms. The sensitivity to the size of the offshore array, the inter-turbine spacing, and the details of the wind-farm parameterization is assessed. ☐ In the second part of this dissertation, a new hybrid wind farm parameterization (a.k.a. hybrid model) is developed, which is not based on physical processes or conservation laws, but on a multiple linear regression of the results of sophisticated, high-resolution large-eddy simulations (LES) with simple geometric properties of the wind farm layout. The need for the new hybrid model arises from three previously-unknown weaknesses in the current wind farm parameterization in WRF, i.e., it neglects the effects of wind direction, it is insensitive to the relative position of the wind turbines within the farm, and it injects excessive TKE in the atmosphere. The new hybrid parameterization, however, successfully remedies these weaknesses. After validations against observations collected at an existing offshore wind farm (Lillgrund in Sweden) and against LES results at three hypothetical wind farms, the wind speed deficit and TKE predicted with the hybrid model are found to be in excellent agreement with the LES results and the wind power production estimated with the hybrid model also performs well compared with the observation data. In conclusion, wind turbine position, wind direction, and added TKE are essential to properly model wind farm effects on the surroundings and the hybrid wind farm parameterization is a promising tool to incorporate them in meso- and large-scale simulations.
