  • Advantages of Applying Large-Scale Energy Storage for Load-Generation Balancing
    energies Article Advantages of Applying Large-Scale Energy Storage for Load-Generation Balancing Dawid Chudy * and Adam Le´sniak Institute of Electrical Power Engineering, Lodz University of Technology, Stefanowskiego Str. 18/22, PL 90-924 Lodz, Poland; [email protected] * Correspondence: [email protected] Abstract: The continuous development of energy storage (ES) technologies and their wider utiliza- tion in modern power systems are becoming more and more visible. ES is used for a variety of applications ranging from price arbitrage, voltage and frequency regulation, reserves provision, black-starting and renewable energy sources (RESs), supporting load-generation balancing. The cost of ES technologies remains high; nevertheless, future decreases are expected. As the most profitable and technically effective solutions are continuously sought, this article presents the results of the analyses which through the created unit commitment and dispatch optimization model examines the use of ES as support for load-generation balancing. The performed simulations based on various scenarios show a possibility to reduce the number of starting-up centrally dispatched generating units (CDGUs) required to satisfy the electricity demand, which results in the facilitation of load-generation balancing for transmission system operators (TSOs). The barriers that should be encountered to improving the proposed use of ES were also identified. The presented solution may be suitable for further development of renewables and, in light of strict climate and energy policies, may lead to lower utilization of large-scale power generating units required to maintain proper operation of power systems. Citation: Chudy, D.; Le´sniak,A. Keywords: load-generation balancing; large-scale energy storage; power system services modeling; Advantages of Applying Large-Scale power system operation; power system optimization Energy Storage for Load-Generation Balancing.

  • A New Era for Wind Power in the United States
    Chapter 3 Wind Vision: A New Era for Wind Power in the United States 1 Photo from iStock 7943575 1 This page is intentionally left blank 3 Impacts of the Wind Vision Summary Chapter 3 of the Wind Vision identifies and quantifies an array of impacts associated with continued deployment of wind energy. This 3 | Summary Chapter chapter provides a detailed accounting of the methods applied and results from this work. Costs, benefits, and other impacts are assessed for a future scenario that is consistent with economic modeling outcomes detailed in Chapter 1 of the Wind Vision, as well as exist- ing industry construction and manufacturing capacity, and past research. Impacts reported here are intended to facilitate informed discus- sions of the broad-based value of wind energy as part of the nation’s electricity future. The primary tool used to evaluate impacts is the National Renewable Energy Laboratory’s (NREL’s) Regional Energy Deployment System (ReEDS) model. ReEDS is a capacity expan- sion model that simulates the construction and operation of generation and transmission capacity to meet electricity demand. In addition to the ReEDS model, other methods are applied to analyze and quantify additional impacts. Modeling analysis is focused on the Wind Vision Study Scenario (referred to as the Study Scenario) and the Baseline Scenario. The Study Scenario is defined as wind penetration, as a share of annual end-use electricity demand, of 10% by 2020, 20% by 2030, and 35% by 2050. In contrast, the Baseline Scenario holds the installed capacity of wind constant at levels observed through year-end 2013.

  • REPOWERING AMERICA: Transmission Investment for Economic Stimulus and Climate Change
    REPOWERING AMERICA: Transmission investment for economic stimulus and climate change May 2021 Prepared for: London Economics International LLC 717 Atlantic Avenue, Suite 1A Boston, MA 02111 www.londoneconomics.com Disclaimer The analysis London Economics International LLC (“LEI”) provides in this study is intended to illustrate the potential economic benefit of transmission investment in terms of GDP and employment for the American economy (to support economic recovery), and as a potential public policy tool (to support longer term environmental goals to reduce carbon emissions, which will itself create positive economic benefits). While LEI has taken all reasonable care to ensure that its analysis is complete, the interplay of electric infrastructure investment and dynamics of local economies are highly complex, and thus this illustrative analysis does not quantify all tradeoffs and substitution effects, nor attempt to quantify various positive effects from reduced carbon emissions and containment of damages from Climate Change. Furthermore, certain recent developments in the US economy and transmission investment plans of various regions of the US may or may not be included in LEI’s illustrative analysis. This report is not intended to be an evaluation of any specific transmission investment or a definitive assessment of future economic conditions in the US.

  • Evolving Relationship Between Nuclear and Renewables in a Near-Zero Energy System
    EVOLVING RELATIONSHIP BETWEEN NUCLEAR AND RENEWABLES IN A NEAR-ZERO ENERGY SYSTEM Mengyao Yuan, Carnegie Institution for Science, 1-650-319-8904, [email protected] Fan Tong, Carnegie Institution for Science, 1-650-319-8904, [email protected] Lei Duan, Carnegie Institution for Science, 1-650-319-8904, [email protected] Nathan S. Lewis, California Institute of Technology, 1-626-395-6335, [email protected] Ken Caldeira, Carnegie Institution for Science, 1-650-319-8904, [email protected] Overview The electricity sector worldwide has seen increasing integration of variable renewable energy resources such as wind and solar photovoltaic (PV). This trend may continue in the coming decades, contributing to a transformation towards a near-zero emissions energy system. The high variability of renewable resources poses challenges to system robustness, highlighting the importance of reliable storage and flexible baseload power needed to fill the gap between intermittent generation and variable demand. Nuclear energy represents one prominent form of low-carbon baseload power. Recently, however, nuclear power plants have faced substantial competition from low-cost renewables and natural gas and are exposed to risks of early retirement in countries such as the US and Germany (Froggatt and Schneider 2015, Roth and Jaramillo 2017). Nuclear energy is traditionally considered a non-dispatchable generation technology, although recent French experience suggests that nuclear power plants can be operated flexibly to assume a more load-following role (Lokhov 2011). Nuclear power plants are also characterized by high fixed costs and low variable costs (Lokhov 2011). High fixed costs motivate high capacity factors, so even if nuclear power plants can be made technically dispatchable, there can be economic incentive to operate them as baseload generation.
