Integration of Renewables in Power Systems by Multi-Energy System Interaction

This book focuses on the interaction between different energy vectors, that is, between electrical, thermal, gas, and transportation systems, with the purpose of optimizing the planning and operation of future energy systems. More and more renewable energy is integrated into the electrical system, and to optimize its usage and ensure that its full production can be hosted and utilized, the power system has to be controlled in a more flexible manner. In order not to overload the electrical distribution grids, the new large loads have to be controlled using demand response, perchance through a hierarchical control set-up where some controls are dependent on price signals from the spot and balancing markets. In addition, by performing local real-time control and coordination based on local voltage or system frequency measurements, the grid hosting limits are not violated

Emerging Converter Topologies and Control for Grid Connected Photovoltaic Systems

Continuous cost reduction of photovoltaic (PV) systems and the rise of power auctions resulted in the establishment of PV power not only as a green energy source but also as a cost-effective solution to the electricity generation market. Various commercial solutions for grid-connected PV systems are available at any power level, ranging from multi-megawatt utility-scale solar farms to sub-kilowatt residential PV installations. Compared to utility-scale systems, the feasibility of small-scale residential PV installations is still limited by existing technologies that have not yet properly address issues like operation in weak grids, opaque and partial shading, etc. New market drivers such as warranty improvement to match the PV module lifespan, operation voltage range extension for application flexibility, and embedded energy storage for load shifting have again put small-scale PV systems in the spotlight. This Special Issue collects the latest developments in the field of power electronic converter topologies, control, design, and optimization for better energy yield, power conversion efficiency, reliability, and longer lifetime of the small-scale PV systems. This Special Issue will serve as a reference and update for academics, researchers, and practicing engineers to inspire new research and developments that pave the way for next-generation PV systems for residential and small commercial applications

A holistic framework for improved energy performance in marine manufacturing plants

PhD ThesisWhile the marine industry provides one the most energy-efficient modes of transportation (OECD, 2010), activities of manufacturing plants in this industry, including shipyards and marine equipment manufacturers, are highly energy intensive and environmentally polluting. For instance, a ship is a giant structure consisting of various systems of which construction require very diverse shipyard manufacturing processes such as cutting, bending, blasting, and welding, and so on. Similarly, manufacturing of various machinery and equipment such as marine engines and marine propellers and other onboard equipment and components involve energy-intensive processes such as melting and machining. All the systems and processes are required to be powered using large amounts of energy. Improved energy performance is of great importance for marine manufacturing plants in terms of their business competitiveness because the marine industry represents one of the world`s most open and competitive markets (Stopford, 2009). In such a fiercely competitive market, business factors such as cost-cutting, and good corporate image are imperative to be successful. Also, increased awareness of the effective energy management practices in their production systems will undoubtedly strengthen the ability of marine manufacturers to compete effectively in the open marine market through increased greener corporate image and reduced energy costs. As well as for their benefits, an overall effort from marine manufacturing industries will also contribute to global and national efforts in fighting climate change. Bearing the above motivational reasons, the present study aims to develop a holistic framework for improved energy performance in marine manufacturing plants and to demonstrate the applicability to a typical marine equipment&component manufacturing plant in Turkey. The developed framework consists of the critical energy management themes of Energy Efficiency, Renewable Energy Use, and Demand Response Participation, which together form a holistic energy management framework incorporating all critical aspects of improved energy performance in a manufacturing plant. The application of the proposed framework requires performing a detailed energy audit and a techno-economic feasibility analysis for renewables-based microgrid application with demand response. In this research, a real application case study of a Turkish marine component&equipment manufacturing plant is chosen and exemplified to demonstrate the applicability of the developed energy management approach. A detailed energy audit was conducted in the manufacturing plant iii selected to identify energy saving potentials, of which implementation would reduce the energy consumption of the plant and increase energy efficiency. At the same time, a dedicated power measurement campaign on energy consuming systems of the plant was performed to collect appropriate data to use in the microgrid feasibility analysis, which explored the techno-economic potential of integrating renewable energy use and demand response participation. The main findings of the proposed framework in the research has demonstrated that there exists a considerable energy efficiency improvement potential within a marine manufacturing plant through the application of various technical and organisational energy saving potentials that can be identified conducting a detailed energy audit. In addition, it has been found that a noteworthy level of power self-sufficiency can be achieved for the plant by exploiting the onsite renewable energy sources through the application of a microgrid. The contribution of demand response participation, with measures such as such peak shaving and grid arbitrage through energy storage to the economic feasibility of the microgrid investment, is found to be remarkable. This research can be seen as one of the first attempts in the area of energy management in marine manufacturing, which makes the current research novel. A significant contribution has been made in addressing the importance of improved energy performance and energy management issues among marine manufacturing plants such as shipyards and marine component/equipment manufacturers. Creating an increased awareness towards the importance of effective energy management and culture, it is envisaged that this study can be utilized by manufacturing plants of the marine industry to improve their energy performance. The developed methodology was successfully applied to a real case, this success can be translated into another case in similar nature by tailoring the developed methodology to the particular needs of other cases.Ministry of National Education of Turke

IEA ECES Annex 31 Final Report - Energy Storage with Energy Efficient Buildings and Districts: Optimization and Automation

At present, the energy requirements in buildings are majorly met from non-renewable sources where the contribution of renewable sources is still in its initial stage. Meeting the peak energy demand by non-renewable energy sources is highly expensive for the utility companies and it critically influences the environment through GHG emissions. In addition, renewable energy sources are inherently intermittent in nature. Therefore, to make both renewable and nonrenewable energy sources more efficient in building/district applications, they should be integrated with energy storage systems. Nevertheless, determination of the optimal operation and integration of energy storage with buildings/districts are not straightforward. The real strength of integrating energy storage technologies with buildings/districts is stalled by the high computational demand (or even lack of) tools and optimization techniques. Annex 31 aims to resolve this gap by critically addressing the challenges in integrating energy storage systems in buildings/districts from the perspective of design, development of simplified modeling tools and optimization techniques
