Book Description
Power systems must be actively managed to maintain a steady balance between supply and demand. This is already a complex task as demand varies continually. But what happens when supply becomes more variable and less certain, as with some renewable sources of electricity like wind and solar PV that fluctuate with the weather? to what extent can the resources that help power systems cope with the challenge of variability in demand also be applied to variability of supply? How large are these resources? and what share of electricity supply from variable renewables can they make possible? There is no one-size-fits-all answer. the ways electricity is produced, transported and consumed around the world exhibit great diversity. Grids can cross borders, requiring co-ordinated international policy, or can be distinct within a single country or region. and whether found in dispatchable power plants, storage facilities, interconnections for trade or on the demand side, the flexible resource that ensures the provision of reliable power in the face of uncertainty likewise differs enormously. Written for decision makers, Harnessing Variable Renewables: a Guide to the Balancing Challenge sheds light on managing power systems with large shares of variable renewables. It presents a new, step-by-step approach developed by the IEA to assess the flexibility of power systems, which identifies the already present resources that could help meet the twin challenges of variability and uncertainty.

Book Description
Increased attention has focused on scenarios of rapid and deep decarbonization of the U.S. electricity supply, with least-cost solutions typically involving significant expansion of renewable energy, energy storage, and transmission assets. Strategies that enable the integration of renewable energy projects while minimizing transmission expansion could be especially valuable in the future. It is within this context that the concept of hybrid power plants (or hybrid energy systems) has gained prominence. One specific example is the FlexPower concept, which seeks to demonstrate how coupling variable renewable energy (VRE) and energy storage technologies can result in renewable-based hybrid power plants that provide full dispatchability and a full range of reliability and resiliency services, similar to or better than fuel-based power plants. To help inform and evaluate the FlexPower concept, this report quantifies the temporal complementarity of pairs of colocated VRE (wind, solar, and hydropower) resources, based on their native generation profiles. The combined output from complementary resources - i.e., resources whose generation profiles are anticorrelated or out of phase with one another - will be spread more evenly across time, resulting in reduced variability. In turn, hybrid power plants comprising complementary resources can have increased capacity factors, reduced curtailment, and cost synergies due to smaller interconnection and energy storage requirements for smooth and dispatchable generation. Through the evaluation of two complementarity metrics over annual and seasonal timescales, we find evidence that combining multiple VRE resources can reduce the variability in daily plant output across many regions of the United States. In general, complementarity signals are strongest for resource pairs that involve solar photovoltaics (PV), including wind-PV and hydropower-PV combinations. Complementarity varies on a seasonal and regional basis, both in terms of the strength of potential synergies and the resource pairs for which synergies are observed. In the western United States, colocated wind and PV resources are complementary in the Central Valley of California, and output from hydropower dams complements that of colocated PV along the Colorado River, near Tahoe, California, and in northern Utah. In the wind belt and surrounding regions, colocated wind and PV are highly complementary, and generation from hydropower dams in the northern latitudes complements colocated PV (although these dams tend to have small capacities, = 20 megawatts). In the Northeast, both wind and hydropower resources are moderately-to-strongly complementary with colocated PV, while the synergies between wind and hydropower are more muted. In the Southeast, complementarity among all evaluated resource pairs is moderate. This report focuses on the temporal complementarity of pairs of wind, solar, and hydropower resources , but complementarity on its own cannot predict the competitiveness of hybrid energy systems. The economics of a power plant ultimately depend on its ability to deliver power during periods of greatest need and value, and high complementarity may not be optimal from a net economic perspective, accounting for all cost and value categories. In addition, complementarity provides initial insights into where the FlexPower concept could generate transmission and/or interconnection benefits, but the goals of FlexPower are much broader. Insights derived from this complementarity analysis can help with scenario design in operational models to provide a more complete picture of the value proposition of the FlexPower concept, including the addition of energy storage.

Book Description
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.

Book Description
The wind regime in Colombia has been rated among the best in South America. However, under the current circumstances, and on its own, the interconnected system would not likely promote wind power. This report is targeted to analysts, planners, operators, generators and decision makers in Colombia and other countries in the region and provides a set of policy options to promote the use of wind power. The potential instruments assessed in this study include financial instruments, government fiscal mechanisms, and adjustments to the regulatory system. The single most effective policy instrument to promote wind power in Colombia consists on valuing the firm energy offered by wind, its potential complementarity to the hydrological regime and enabling wind power an access to reliability payments.

Book Description
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.

Book Description
This addition to the ISOR series addresses the analytics of the operations of electric energy systems with increasing penetration of stochastic renewable production facilities, such as wind- and solar-based generation units. As stochastic renewable production units become ubiquitous throughout electric energy systems, an increasing level of flexible backup provided by non-stochastic units and other system agents is needed if supply security and quality are to be maintained. Within the context above, this book provides up-to-date analytical tools to address challenging operational problems such as: • The modeling and forecasting of stochastic renewable power production. • The characterization of the impact of renewable production on market outcomes. • The clearing of electricity markets with high penetration of stochastic renewable units. • The development of mechanisms to counteract the variability and unpredictability of stochastic renewable units so that supply security is not at risk. • The trading of the electric energy produced by stochastic renewable producers. • The association of a number of electricity production facilities, stochastic and others, to increase their competitive edge in the electricity market. • The development of procedures to enable demand response and to facilitate the integration of stochastic renewable units. This book is written in a modular and tutorial manner and includes many illustrative examples to facilitate its comprehension. It is intended for advanced undergraduate and graduate students in the fields of electric energy systems, applied mathematics and economics. Practitioners in the electric energy sector will benefit as well from the concepts and techniques explained in this book.
