Khattab, Mervat A. Badr, Essam Tawfik El Shenawy, Hassan H. Sharawy and Marwa S. Shalaby Chapter 11 225 Optimization of Renewable Energy-Based Smart Micro-Grid System by Marwa Mohsen Ibrahim Abd El-Rahman XII Preface The reduction of greenhouse gases emissions is a major governmental goal worldwide. The European Union, United Kingdom, United States and Canada have embraced a goal of achieving “net-zero” greenhouse gas emissions economy-wide by 2050. The main target is to move away from fossil fuels in the electricity sector, and then switch to clean power to fuel transportation, buildings and industry. Therefore intensive research and collaborative projects dealing with the installation of many wind turbines and solar panels, both onshore and offshore, are taking place with the main objective of decarbonizing electricity grid systems through the exploitation of wind and solar power. In fact, the rapidly plunging costs of wind and solar resources makes renewable energy the least costly option for new clean and reliable power. This book presents relevant achievements in the expanding field of wind farms mod- eling and hybrid systems optimization. The contributing authors combine simulation and optimization of wind farms and hybrid wind/solar systems with description of the implemented mathematical approaches. All chapters were reviewed for their technical contents as stated by the individual authors. As such, the editor assumes no responsibility for the accuracy and completeness of the typing itself. Section I is comprised of six chapters tackling the global wind energy market and design optimization of wind farms, which is a multidisciplinary engineering challenge and mainly consists of selecting and distributing wind turbines on the wind farm site as well as analyzing energy production. Chapter 1 provides an overview of the world wind energy market, current and forecasting development globally, and cost of wind energy historical growth. Chapter 2 presents a systematic approach to simulate an offshore wind farm for smart cities. The subsystems of several variable-pitch wind turbines, namely rotor blades, drive train, and induction generator, are modeled to form a wind farm. The total output power of the wind farm by considering multiple wind turbines with the wake losses (using the Jensen wake model) can be simulated with any input wind speed. In order to validate the accuracy of the simulation, a case study on a German offshore wind farm called NordseeOst is presented. The simulation shows promising results with an average error of approximately 5% when compared with the real-time output of the wind farm. The results

It will convert the old, conventional economy into a new, sustainable economy that is environmentally sound, economically viable, and socially responsible. Therefore, there is a need for quick actions by everyone who wants to move toward energy-efficient development and new environmentally friendly behavior. This can be achieved by setting specific guidelines of how to proceed, where to start, and what knowledge is needed to implement such plans and initiatives. This paper seeks to contribute to this very important issue by appraising the ability of full-scale implementation of RES combined with energy storage in an island power system. The Greek island power system of Astypalaia is used as a case study where a battery energy storage system (BESS), along with wind turbines (WTs), is examined to be installed as part of a hybrid power plant (HPP). The simulation’s results showed that the utilization of HPP can significantly increase RES penetration in parallel with remarkable fuel cost savings. Finally, the fast response of BESS can enhance the stability of the system in the case of disturbances.
