This book was released on 2018 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. electricity grid's ongoing transformation to integrate renewable or distributed generation, address aging infrastructure, and improve grid resilience and reliability all motivate increasing the base of available demand-side resources that offer services to the grid. Water systems have several characteristics relevant to increasing the amount of demand-side services provided to the electric grid, including unique physical and chemical properties, location within urban areas, inextricable linkages between energy and water use, and untapped potential in the space. This research addresses opportunities to provide two types of demand-side service from within the water sector: load management and energy efficiency. Improved pump scheduling at municipal pump stations was explored in a case study to quantify the influence of electric rate design on the amount of load management that water utilities can affordably provide. The analysis found significant potential for electric and water utilities to cooperate on rate design and load scheduling, and that rate structure is a key enabler of mutually beneficial arrangements. Environmental and economic impacts of community-scale water recycling were addressed through the formulation of an optimal capacity and dispatch model. The model was demonstrated in a case study, which found that the community-scale system can be economically feasible in certain areas and might significantly decrease reliance on central water utilities, but that relying on grid electricity will significantly increase demand and associated emissions. The results motivate exploration of community-scale systems within microgrids with increased availability of renewable energy. In the residential sector, very high sampling rate data is used to develop machine learning classifiers to categorize end use water events by appliance type. Classifier performance is shown to improve with the addition of coincident electricity data and dedicated sub-meter data. Results from this work have potential to improve customer awareness of water use and facilitate adoption of efficient appliances or conservation behaviors. This work is extended via a spatio-economic analysis of cost effectiveness for residential water-related appliance retrofits. The analysis unites novel data sets to create an interactive online tool that allows users to evaluate energy savings and avoided emissions based on heterogenous usage, behavioral parameters, and geographic factors. Together, this body of research identifies promising opportunities for new technology, operational strategies, and policies within the water sector to support ongoing transformation towards a cleaner, responsive, and resilient electric grid.
Download or read book Reducing Electricity Grid Imbalances Through Energy Demand Management of Water Delivery Infrastructure written by Robert Good and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of a water supply utility to perform energy load shifting into periods of energy imbalance on California’s statewide energy grid was investigated for the reclaimed water distribution system operated by the Moulton Niguel Water District in an offline hydraulic model. The energy generation, curtailment, and greenhouse gas (GHG) emission trends of California’s statewide energy grid operated by the California Independent System Operator were investigated to determine the key time periods to target with energy load shifting. Different energy load shifting scenarios were analyzed to minimize energy consumption, the carbon intensity of energy generated to meet demand, statewide energy curtailment, and statewide energy overgeneration. Reductions in energy use and associated emissions resulted from many of the potential energy load shifting scenarios. The offline hydraulic model demonstrated that it is possible for water delivery utilities to shift energy loads to address statewide energy imbalances while reducing total energy use and GHG emissions without negatively impacting water customer experience.

Available in PDF, EPUB and Kindle. Book excerpt: Reliable operation of the electric grid which comprises of instantaneously matching electricity demand and supply is a tier one security concern and has received increased attention in recent years. This is a challenging task as both electricity demand and supply are characterized by variability and uncertainty; the volatility on the supply end originating from increased integration of renewable energy in power generation. Electricity demand typically peaks in the late afternoons whereas wind and solar generation peak in the early mornings and mid-day respectively. To reconcile this electricity supply and demand mismatch, energy storage is employed for storing excess power generated during off-peak demand periods. Correspondingly, stored power is discharged during peak electricity demand hours. Electricity storage is however presently expensive and current grid storage devices are insufficient to ensure reliable electric grid operation. Standby generators with fast ramp rates which are generally more expensive to run are also employed when needed. A solution to this problem involves motivating end-users of electricity to modify their demand patterns in manner that enhances grid stability. This activity, referred to as demand response (DR) can help relieve the strain on the grid by tailoring end-user power consumption to match the time varying supply of electricity. Chemical industries that are power-intensive can provide valuable DR as they represent localized grid loads with end products that are generally easier and cheaper to store compared to electricity. These industries can ramp production during off-peak power demand hours storing excess product and reduce production rates when power demand peaks while depleting inventory to meet any required product demand. However, the operation of chemical industries are subject to strict constraints including; economic (e.g., reliable product delivery), feasibility (e.g., limits on process variables) or safety concerns. Additionally, the dynamics of chemical processes are typically described by high-order non-linear models and ramp rates and capacity limits alone, which are typically employed on the grid side to manage demand response activities, are not sufficient to characterize the transient nature of chemical processes. In this dissertation, we employ modeling techniques and production scheduling to evaluate the provision of demand response by chemical industries in highly volatile electricity markets. We develop and illustrate the use of suitable dynamic models to represent the chemical plant operation while providing fast-paced DR. As fast DR contribute significantly to the solution pool available for handling power grid contingencies, this study will aid the smoother deployment of industrial chemical loads as grid support devices while ensuring safe and feasible operation of the chemical plant

This book was released on 2015-04-13 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Energy Conversion for Electricity and Coproducts Comprehensive and a fundamental approach to the study of sustainable fuel conversion for the generation of electricity and for coproducing synthetic fuels and chemicals Both electricity and chemicals are critical to maintain our modern way of life; however, environmental impacts have to be factored in to sustain this type of lifestyle. Sustainable Energy Conversion for Electricity and Coproducts provides a unified, comprehensive, and a fundamental approach to the study of sustainable fuel conversion in order to generate electricity and optionally coproduce synthetic fuels and chemicals. The book starts with an introduction to energy systems and describes the various forms of energy sources: natural gas, petroleum, coal, biomass, and other renewables and nuclear. Their distribution is discussed in order to emphasize the uneven availability and finiteness of some of these resources. Each topic in the book is covered in sufficient detail from a theoretical and practical applications standpoint essential for engineers involved in the development of the modern power plant. Sustainable Energy Conversion for Electricity and Coproducts features the following: Discusses the impact of energy sources on the environment along with an introduction to the supply chain and life cycle analyses in order to emphasize the holistic approach required for sustainability. Not only are the emissions of criteria pollutants addressed but also the major greenhouse gas CO2 which is essential for the overall sustainability. Deals with underlying principles and their application to engineering including thermodynamics, fluid flow, and heat and mass transfer which form the foundation for the more technology specific chapters that follow. Details specific subjects within energy plants such as prime movers, systems engineering, Rankine cycle and the Brayton–Rankine combined cycle, and emerging technologies such as high-temperature membranes and fuel cells. Sustainable energy conversion is an extremely active field of research at this time. By covering the multidisciplinary fundamentals in sufficient depth, this book is largely self-contained suitable for the different engineering disciplines, as well as chemists working in this field of sustainable energy conversion.

Available in PDF, EPUB and Kindle. Book excerpt: Regulatory Choices offers the first comprehensive economic history of energy policy and its consequences for California, where some of the most innovative and far-ranging programs of regulatory reform have originated. The authors of this volume have gathered together an impressive wealth of material about actual policy decisions and their repercussions and have subjected their findings to astute economic analysis. This book will serve for years to come as an invaluable reference on the costs and effects of various energy policies. With its focus on bringing prices in alignment with the true cost of producing power and delivering it to the customer, the first part of the book outlines the issue of setting utility rates and considers some of the proposals to provide regulated industries with incentives to respond to economic and environmental concerns. The problems of energy supply occupy the second part of the book, which includes a survey of the costs of alternative energy sources and estimates of their environmental impacts, as well as a case study of the construction of the Diablo Canyon nuclear power plant. The book concludes by documenting the results of subsidy programs that were designed to target the development of wind power and residential energy conservation. Regulators, we learn, have a mixed record when it comes to managing the production of energy. Some conservation programs have enjoyed considerable economic success, particularly those that correct a lack of consumer information. Others, such as the renewable energy tax credits or programs designed to subsidize new technologies, have cost much more than the value of the energy they have saved. What emerges clearly from this study is that regulated industries are not immune from the forces of competition. This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact.
