This book presents a comprehensive definition of smart grids and their benefits, and compares smart and traditional grids. It also introduces a design methodology for stand-alone hybrid renewable energy system with and without applying the smart grid concepts for comparison purposes. It discusses using renewable energy power plants to feed loads in remote areas as well as in central power plants connected to electric utilities. Smart grid concepts used in the design of the hybrid renewable power systems can reduce the size of components, which can be translated to a reduction in the cost of generated energy. The proposed hybrid renewable energy system includes wind, photovoltaic, battery, and diesel, and is used initially to feed certain loads, covering the load required completely. The book introduces a novel methodology taking the smart grid concept into account by dividing the loads into high and low priority parts. The high priority part should be supplied at any generated conditions. However, the low priority loads can be shifted to the time when the generated energy from renewable energy sources is greater than the high priority loads requirements. The results show that the use of this smart grid concept reduces the component size and the cost of generated energy compared to that without dividing the loads. The book also describes the use of smart optimization techniques like particle swarm optimization (PSO) and genetic algorithm (GA) to optimally design the hybrid renewable energy system. This book provides an excellent background to renewable energy sources, optimal sizing and locating of hybrid renewable energy sources, the best optimization methodologies for sizing and designing the components of hybrid renewable energy systems, and offers insights into using smart grid concepts in the system’s design and sizing. It also helps readers understand the dispatch methodology and how to connect the system’s different components, their modeling, and the cost analysis of the system.

Wind power is fast becoming one of the leading renewable energy sources worldwide, not only from large scale wind farms but also from the increasing penetration of stand-alone and hybrid wind energy systems. These systems are primarily of benefit in small-scale applications, especially where there is no connection to a central electricity network, and where there are limited conventional fuel resources but available renewable energy resources. By applying appropriate planning, systems selection and sizing, including the integration of energy storage devices to mitigate variable energy generation patterns, theses systems can supply secure reliable and economic power to remote locations and distributed micro-grids.Stand-alone and hybrid wind energy systems is a synthesis of the most recent knowledge and experience on wind-based hybrid renewable energy systems, comprehensively covering the scientific, technical and socio-economic issues involved in the application of these systems.Part one presents an overview of the fundamental science and engineering of stand-alone and hybrid wind energy systems and energy storage technology, including design and performance optimisation methods and feasibility assessment for these systems.

Energy security, rising energy prices (oil, gas, electricity), 'peak oil', environmental pollution, nuclear energy, climate change and sustainable living are hot topics across the globe. Meanwhile, abundant and perpetual wind resources offer opportunities, via recent technological developments, to provide part of the solution to address these key issues. The rapid growth of large-scale wind farm installations has now led to the generation of clean electricity for tens of millions of homes around the world. However, despite the potential to reduce the losses and costs associated with transmission and to use local wind acceleration techniques to improve energy yields, the potential for urban wind energy has yet to be realised. Although there is increasing public interest, the uptake of urban wind energy in suitable areas has been slow. This is in part due to a lack of understanding of key issues such as: available wind resources; technology integration; planning processes (include assessment of environmental impacts and public safety due to close proximity to people and property); energy consumption in buildings versus energy production from turbines; economics (including grants, subsidies, maintenance); and the effect of complex urban windscapes on performance. Urban Wind Energy attempts to illuminate these areas, addressing common concerns highlighting pitfalls, offering real world examples and providing a framework to assess viability in energy, environmental and economic terms. It is a comprehensive guide to urban wind energy for architects, engineers, planners, developers, investors, policy-makers, manufacturers and students as well as community organisations and home-owners interested in generating their own clean electricity.
