Due to the increasing world population, energy consumption is steadily climbing, and there is a demand to provide solutions for sustainable and renewable energy production, such as wind turbines and photovoltaics. Power electronics are being used to interface renewable sources in order to maximize the energy yield, as well as smoothly integrate them within the grid. In many cases, power electronics are able to ensure a large amount of energy saving in pumps, compressors, and ventilation systems. This book explains the operations behind different renewable generation technologies in order to better prepare the reader for practical applications. Multiple chapters are included on the state-of-the-art and possible technology developments within the next 15 years. The book provides a comprehensive overview of the current renewable energy technology in terms of system configuration, power circuit usage, and control. It contains two design examples for small wind turbine system and PV power system, respectively, which are useful for real-life installation, as well as many computer simulation models.

Abstract

In this chapter, essential statistics demonstrating the increasing role of renewable energy generation are first discussed. A state-of-the-art review section covers the fundamentals of wind turbine and photovoltaic (PV) systems. Schematic diagrams illustrating the main components and system topologies are included. Also, the increasing role of power electronics is explained as an enabler for renewable energy integration and for future power systems and smart grids. Recent examples of research and development, including new devices and system installations for utility power plants and for residential and commercial applications, are provided. Fuel cells, solar thermal, wave generators, and energy storage systems are also briefly presented and illustrated. Challenges and future trends for the technologies in 2025 are summarized in a table for onshore and offshore wind energy; solar power, including PV and concentrating solar power; wave energy; fuel cells; and storage with batteries and hydrogen, respectively. Recommended further readings on topics of electric power engineering for renewable energy are included in the final section.

1.1Introduction

Sustainable energy supply remains to be a main requirement of modern society in order to respond to the increased energy demand caused by the larger consumption especially due to population growth. For a long time, the energy boom has been based on fossil fuels. Unfortunately, not only the supply of oil, coal, and natural gas is limited, but there exist also major pollution and environmental concerns associated with using the traditional energy sources and alternatives are important.

Renewable energy technologies are seen as some of the most important solutions for the future, and they need to be further developed in this century in order to take over most of the energy production. Many emerging technologies exist and they have different levels of maturity. The scale of implementation is not the same either. Most of the renewable technologies are dependent on weather conditions, and they are challenging in respect to the integration into the grid system. These issues need to be fully solved—how to make a power system that is able to cope with a very high penetration of renewables, which also involves the development of smart grid systems. Such systems may include microgrids and energy storage facilities, and, in many cases, they will combine the electric power system with other energy carriers like heating/cooling and gas as well as look at how to use transportation as a resource.

Figure 1.1 shows the worldwide energy demand in the past decades and also the estimated energy demand until 2030. As it can be observed, due to the continuous increase in gross domestic product, the overall energy demand is expected to increase by more than 50% by 2030 [1]. To achieve this primary goal, renewable energy will be an important part in the foreseeable future energy production (hydro, renewable and biomass, etc.).
