Preface

As the electricity demand increases day by day, the dependence on fossil fuels and harmful emissions that affect health and the environment also increase. So, the best practice to overcome these problems is obtaining energy from the natural resources such as wind, solar, and tide, which are renewable in nature. With the traditional electric setup, it is highly impossible to achieve reliable and efficient power delivery. Thus, a new advanced version or modernization is necessary on the traditional electric grid architecture to overcome such glitches, and the solution is smart grid. The smart grid technology gives a roadmap for efficient, reliable, and clean future electric power delivery and also provides an opportunity for the effective integration of renewable energy sources. The intermittent energy generation of the renewable sources can be overcome by integrating energy storage systems such as battery energy storage system into the power grid. This integration needs a successful coordination between renewable power generation units, energy storage systems, and the power grid. Indeed, this coordination requires robust and innovative controls. The microgrid provides better opportunities for the consumers also to become a producer with highly efficient computing algorithms and triggering techniques. Furthermore, to reduce the stress on power system due to the uncertainty and inherent intermittence of renewable power generation units, the smart grid structure should consist of the main grid and multiple embedded microgrids.

This book starts with an overview of renewable energy technologies, smart grid technologies, and energy storage systems and covers the details of renewable energy integration with smart grid and the corresponding controls. This book provides better views on the power scenario in developing countries. The requirement of the integration of smart grid along with the energy storage systems is deeply discussed to acknowledge the importance of sustainable development of a smart city. The methodologies are made quite possible with highly efficient power convertor topologies and intelligent control schemes. These control schemes are capable of providing better control with the help of machine intelligence techniques and artificial intelligence. The book also addresses modern power convertor topologies and the corresponding control schemes for renewable energy integration with smart grid. The design and analysis of power converters that are used for the grid integration of solar PV along with simulation and experimental results are illustrated. The protection aspects of the microgrid with power electronic configurations for wind energy systems are elucidated. The book also discusses the challenges and mitigation measure in renewable energy integration with smart grid. This book serves to be a better material for the engineers and researchers working on microgrid, smart grid, and computing algorithms for converter and inverter circuits.
