This book was released on 2013-02-27 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper ‘Challenges and Approaches to Electricity Grids Operations and Planning with Increased Amounts of Variable Renewable Generation: Emerging Lessons from Selected Operational Experiences and Desktop Studies’ focuses on analyzing the impacts of variable renewable energy on the operation and planning of the the power system (mostly, generation system). It is aimed at informing stakeholders in power utilities, regulatory bodies and other relevant audiences, on the fundamentals of technical challenges and approaches to operate electricity grids with renewable energy. It covers renewable energy as a whole, but in particular, focusses on wind and solar energy. It also presents three case studies of countries, including China, Gemany and Spain. The total worldwide installed capacity of wind and solar projects is growing rapidly, and several countries are noticing increased penetrations of wind and solar in their electricity generation mix. In addition to operating experience being gained from adding wind and solar capacity, several grid integration studies have been performed that assess potential grid and operating impacts from adding higher amounts of wind and solar capacity. Perhaps just as important, the electric power industry and those that conduct research on grid integration have not found a maximum level of variable generation that can be reliably incorporated, and it is clear that it is as much an economic question (how much cost in additional reserves or grid impacts is acceptable) as a technical question regarding grid operators’ ability to adapt to the new challenges. In addition, while their contributions to capacity or “firm” power and associated costs are different from those of conventional power sources, variable renewable generation technologies can contribute to long-term system adequacy and security. The paper describes on the contribution of variable power sources to long-term supply adequacy requirements, i.e. how much sources like wind and solar power contribute to “firm supply” in a system. It also describes methods to find out to what extent they contribute and at what cost. It also aims at providing indicative answers to how costs to system operations be determined and when and how an integration study be done to estimate the short-term reserve costs of renewable energy. The concepts in the paper should be of interest, especially to grid planers. For grid operators, the paper summarizes a menu of strategies that the operational practices and desktop research tell about managing wind in a system at different levels of penetration. It also elucidates available strategies, amongst other crucial questions of operational impacts and challenges that operators need to be aware of, to integrate variable generation.

Available in PDF, EPUB and Kindle. Book excerpt: The integration of renewable energy resources into the electricity grid presents an important challenge. This book provides a review and analysis of the technical and policy options available for managing variable energy resources such as wind and solar power. As well as being of value to government and industry policy-makers and planners, the volume also provides a single source for scientists and engineers of the technical knowledge gained during the 4-year RenewElec (renewable electricity) project at Carnegie Mellon University, the University of Vermont, Vermont Law School, and the Van Ness Feldman environmental law firm. The first part of the book discusses the options for large scale integration of variable electric power generation, including issues of predictability, variability, and efficiency. The second part presents the scientific findings of the project. In the final part, the authors undertake a critical review of major quantitative regional and national wind integration studies in the United States. Based on comparisons among these studies, they suggest areas where improvements in methods are warranted in future studies, areas where additional research is needed to facilitate future improvements in wind integration studies and how the research can be put into practice.
Download or read book Integrating Renewable Generation into Grid Operations Four International Experiences written by and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: International experiences with power sector restructuring and the resultant impacts on bulk power grid operations and planning may provide insight into policy questions for the evolving United States power grid as the electric power systems around the world are responding to a multitude of factors including changing resource mixes and fuel prices, an aging generation fleet with potentially large retirements of baseload generation and numerous policies designed to meet climate goals. Australia, Germany, Japan and the UK were selected to represent a range in the attributes of electricity industry liberalization in order to draw comparisons across a variety of regions in the United States such as California, ERCOT, the Southwest Power Pool and the Southeast Reliability Region. The study draws conclusions through a literature review of the four case study countries with regards to the changing resource mix and the electricity industry sector structure and their impact on grid operations and planning. This paper derives lessons learned and synthesizes implications for the United States based on the challenges faced by the four selected countries. Each country was examined to determine the challenges to their bulk power sector based on their changing resource mix, market structure, policies driving the changing resource mix, and policies driving restructuring. Each country's approach to solving those challenges was examined, as well as how each country's market structure either exacerbated or mitigated the approaches to solving the challenges to their bulk power grid operations and planning. All countries' policies encourage renewable energy generation. To date, relatively high levels of variable renewable generation have been incorporated with few challenges. However, one significant finding included the Low/zero fuel cost of variable renewables and its potential negative impact on long-term resource adequacy. No dominant solution has emerged although a capacity market was introduced in the UK and is being contemplated in Japan. Germany has proposed the Energy Market 2.0 to encourage flexible generation investment. In Australia interconnections to other regions provide added opportunities for balancing that would not be available otherwise, and at this point, has allowed for integration of renewables.

Download or read book Integrating Variable Renewable Energy in Electricity Markets written by Sophia B. Taylor and published by Nova Science Publishers. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many countries, reflecting very different geographies, markets, and power systems, are successfully managing high levels of variable renewable energy on the electric grid, including that from wind and solar energy. This book documents the diverse approaches to effective integration of variable renewable energy among six countries: Australia (South Australia), Denmark, Germany, Ireland, Spain, and the United States (Colorado and Texas), and summarises policy best practices that energy ministers and other stakeholders can pursue to ensure that electricity markets and power systems can effectively co-evolve with increasing penetrations of variable renewable energy. There is no one-size fits all approach; each country has crafted its own combination of policies, market designs, and system operations to achieve the system reliability and flexibility needed to successfully integrate renewables. Notwithstanding this diversity, the approaches all coalesce around five strategic areas: lead public engagement, particularly for new transmission; co-ordinate and integrate planning; develop rules for market evolution that enable system flexibility; expand access to diverse resources and geographic footprint of operations; and improve system operations. This book also underscores the value of countries sharing their experiences. The more diverse and robust the experience base from which a country can draw, the more likely that it will be able to implement an appropriate, optimised, and system-wide approach.
Download or read book Smart and Sustainable Power Systems written by João P. S. Catalão and published by CRC Press. This book was released on 2017-12-19 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: The smart grid initiative, integrating advanced sensing technologies, intelligent control methods, and bi-directional communications into the contemporary electricity grid, offers excellent opportunities for energy efficiency improvements and better integration of distributed generation, coexisting with centralized generation units within an active network. A large share of the installed capacity for recent renewable energy sources already comprises insular electricity grids, since the latter are preferable due to their high potential for renewables. However, the increasing share of renewables in the power generation mix of insular power systems presents a significant challenge to efficient management of the insular distribution networks, mainly due to the variability and uncertainty of renewable generation. More than other electricity grids, insular electricity grids require the incorporation of sustainable resources and the maximization of the integration of local resources, as well as specific solutions to cope with the inherent characteristics of renewable generation. Insular power systems need a new generation of methodologies and tools to face the new paradigm of large-scale renewable integration. Smart and Sustainable Power Systems: Operations, Planning, and Economics of Insular Electricity Grids discusses the modeling, simulation, and optimization of insular power systems to address the effects of large-scale integration of renewables and demand-side management. This practical book: Describes insular power systems, renewable energies, uncertainty, variability, reserves, and demand response Examines state-of-the-art forecasting techniques, power flow calculations, and scheduling models Covers probabilistic and stochastic approaches, scenario generation, and short-term operation Includes comprehensive testing and validation of the mathematical models using real-world data Explores electric price signals, competitive operation of distribution networks, and network expansion planning Smart and Sustainable Power Systems: Operations, Planning, and Economics of Insular Electricity Grids provides a valuable resource for the design of efficient methodologies, tools, and solutions for the development of a truly sustainable and smart grid.
Download or read book Integrating Variable Renewable Energy on Electricity Grids Through a Multi Scaled Energy Modelling Approach written by Madeleine Myrna McPherson and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The global wind and solar PV industry has transitioned from a subsidy-dependent niche market to a commercially viable sector that is dominating global capacity expansions. However, integrating these renewable energy resources, with their variable nature, onto the electricity grid poses new challenges for system operations. This thesis explores variable renewable energy (VRE) integration, through multiple scales of energy modelling and analysis from the integrated assessment model MESSAGE, to the country-scale electricity system model LEAP, and the production cost model introduced in this work entitled SILVER. The MESSAGE and LEAP models have large-scale, long-term representations of the energy system that enable analysis of alternative energy policies, cross-sector environmental impacts, and overarching cost trends, but do not have the spatial-temporal resolution to represent site-specific, variable VRE generation profiles. Thus, SILVER, for the Strategic Integration of Large-capacity Variable Energy Resources, is designed as a highly flexible production cost dispatch tool. Technologically, SILVER represents the full gamut of grid balancing strategies: building flexible and dispatchable generation assets, interconnecting geographically dispersed resources and VRE types, shifting flexible loads through demand response, shifting generation profiles through storage technologies, curtailing excess generation, interconnecting the electricity sector with the transport sector, and improving VRE forecasting methodologies. SILVER relies on hourly wind and solar generation time-series data, produced by the newly developed GRETA (Global Renewable Energy Atlas Time) tool, which has been launched as an open access web-portal. SILVER is applied to three VRE integration applications: moving towards a fully-renewable Ontario electricity system including 87% VRE penetration, demand response, electric vehicles, storage assets, and an expanded transmission network; quantifying storage asset commercial viability in electricity systems with different flexibility factors, VRE penetrations, and financial remuneration mechanisms; and exploring the role of decentralized generation and electric vehicles at a city-scale in a developing country context. The results demonstrate the highly system-specific nature of VRE integration, with the VRE resource typology, the non-VRE system flexibly, VRE penetration, and degree of VRE centralization having significant impacts. The interdependence between these electricity system factors in terms of curtailment rates, GHG emissions, electricity system costs, and flexibility requirements recommends an integrated planning approach.

This book was released on 2017-10-25 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Americans' safety, productivity, comfort, and convenience depend on the reliable supply of electric power. The electric power system is a complex "cyber-physical" system composed of a network of millions of components spread out across the continent. These components are owned, operated, and regulated by thousands of different entities. Power system operators work hard to assure safe and reliable service, but large outages occasionally happen. Given the nature of the system, there is simply no way that outages can be completely avoided, no matter how much time and money is devoted to such an effort. The system's reliability and resilience can be improved but never made perfect. Thus, system owners, operators, and regulators must prioritize their investments based on potential benefits. Enhancing the Resilience of the Nation's Electricity System focuses on identifying, developing, and implementing strategies to increase the power system's resilience in the face of events that can cause large-area, long-duration outages: blackouts that extend over multiple service areas and last several days or longer. Resilience is not just about lessening the likelihood that these outages will occur. It is also about limiting the scope and impact of outages when they do occur, restoring power rapidly afterwards, and learning from these experiences to better deal with events in the future.
