Covers the fundamental concepts and advanced modelling techniques of Doubly Fed Induction Generators accompanied by analyses and simulation results

Filled with illustrations, problems, models, analyses, case studies, selected simulation and experimental results, Advanced Control of Doubly Fed Induction Generator for Wind Power Systems provides the basic concepts for modelling and controlling of Doubly Fed Induction Generator (DFIG) wind power systems and their power converters. It explores both the challenges and concerns of DFIG under a non-ideal grid and introduces the control strategies and effective operations performance options of DFIG under a non-ideal grid.

Other topics of this book include thermal analysis of DFIG wind power converters under grid faults; implications of the DFIG test bench; advanced control of DFIG under harmonic distorted grid voltage, including multiple-loop and resonant control; modeling of DFIG and GSC under unbalanced grid voltage; the LFRT of DFIG, including the recurring faults ride through of DFIG; and more. In addition, this resource:

• Explores the challenges and concerns of Doubly Fed Induction Generators (DFIG) under non-ideal grid
• Discusses basic concepts of DFIG wind power system and vector control schemes of DFIG
• Introduces control strategies under a non-ideal grid
• Includes case studies and simulation and experimental results

Advanced Control of Doubly Fed Induction Generator for Wind Power Systems is an ideal book for graduate students studying renewable energy and power electronics as well as for research and development engineers working with wind power converters.

INTRODUCTION TO WIND POWER GENERATION

CHAPTER 1
INTRODUCTION

In this chapter, an overview of wind power generation and the evolution of wind power systems are briefly introduced, and the challenges and trends in wind power generation are discussed.

1.1 GLOBAL WIND POWER DEVELOPMENT

1.1.1 Global Environment Challenge and Energy Crisis

Nowadays, the human society consumes a huge amount of electricity every year. It is reported by the U.S. Energy Information Administration (EIA) that the global net electricity consumption has grown from 10,395 TWh in 1990 to 20,567 TWh in 2015 [1]. Since most of the electricity is generated from fossil fuels, the increase of the electricity net consumption will lead to large greenhouse gas emissions, and this may cause global warming. The Earth's average surface temperature has risen about 0.74°C for the period 1906–2005, which may cause the sea level rise, widespread melting of snow and ice, or some extreme weather challenges. Furthermore, burning of fossil fuels will produce dust and other chemical materials harmful to humans.

On the other hand, the fossil fuel reserves are limited and unsustainable. Oil will be exhausted in a few decades, followed by natural gas, and coal will also be used up in 200–300 years. The energy crisis brought by the exhaustion of fossil fuels is a long-range challenge for human beings. Many efforts have been made worldwide to try to find an alternative energy.

1.1.2 Renewable Energy Development

Renewable energy is defined as the energy that comes from resources that are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. Typically, the renewable energy includes wind power, photovoltaic (PV) power, hydropower, biomass power, and ocean power. As renewable energy is reproducible and has a low footprint of CO₂, it is regarded as a favorable solution to both the global environment challenge and energy crisis. Rapid deployment of renewable energy has been reported in recent years. Global renewable energy policy multistakeholder network REN21 estimated that by the end of 2016, 30% power generation capacity will come from renewable energy and renewable energy will account for about 24.5% of global electricity generation [2]. Nowadays, the biggest renewable energy generation is from hydropower. However, since the location requirement of the hydropower is limited to lakes or rivers, the worldwide growth of hydropower has become slower in the recent years, which indicates that hydropower is very close to its capacity limit.

The non-hydropower renewable generation, including wind, PV, and biomass, has been growing very fast in the last 10 years. The non-hydropower renewable generation capacity reached 921 GW by the end of 2016, compared to 85 GW in 2004 [2]. The worldwide capacity share of different non-hydro renewable powers by the end of 2016 can be found in Figure 1.1. It is found that wind power has the largest capacity share among the non-hydropower renewable generations. Wind power has reached 56.8% of the non-hydro renewable power capacity.

1.1.3 Wind Energy Development

The wind power generation is regarded as the most widely used non-hydro renewable energy generation. It has a high reserve and is renewable and clean. Besides it produces almost no greenhouse gas emissions. Now at least 83 countries around the world are using wind power to supply their electricity grids [3]. The capacity of wind power installation has grown rapidly for th...
