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


Book Description

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.




Variable Generation, Flexible Demand


Book Description

Variable Generation, Flexible Demand looks at a future in which power system researchers, operators and analysts need to predict variable renewable generation and schedule demand to match it. Contributors survey the significant expansion in the role of flexible demand in balancing supply and demand in conjunction with flexible generation in ‘peaking plants’ and energy storage as the proportion of variable renewable generation rises in many systems across the world. Supported with case studies, the book examines practical ways that demand flexibility can play a constructive role as more systems move towards higher levels of renewable generation in their electricity mix. Examines practical ways that demand flexibility can play a constructive role in future energy systems Reviews the vital role of market design, business models, enabling technologies, policies and regulation in implementation of flexible demand Includes detailed case studies that address the role of flexible demand across transitioning power markets




Planning and Operation Strategies for Enhancing Power System Flexibility in Low-Carbon Energy Transition


Book Description

The global energy system is undergoing a profound transformation from a system based mainly on fossil fuels to a low-carbon one based on variable renewable energy (VRE), such as wind power and solar power, to achieve the 2050 Paris Agreement. By 2050, solar and wind power, with more than 14,500 GW installed capacity, would account for three-fifths of global electricity generation. This transformation comes with significant challenges since high VRE shares will greatly increase system flexibility requirements for balancing supply and demand. Accordingly, all sectors of the power system need to unlock further requisite flexibility through technology, business, and policy innovations, including power supply, transmission, distribution, storage, and demand.




Harnessing Variable Renewables


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.




Integrating Variable Renewable Energy in Electricity Markets


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.
