书名:Big data analytics strategies for the smart grid
前言
This is a practical book, to be sure, but it is also a book about hope and posi- tive change. I am quite sincere. The delivery of electricity is deeply rooted in the principle of universal access; when clean, reliable energy is available it contributes to poverty alleviation, improved social conditions, and enhanced economic development. In the developed world, we know this to be true. The digital fabric of our lives is a testimony to the importance of energy security. Across the globe, we have seen the vital contributions that electrification has brought to the development of economies and an enhanced quality of life. Nonetheless, this supreme engineering achievement has languished, and we are deeply challenged.
Modern electrification systems are degrading and inefficient in myriad ways, yet the complex and difficult operating conditions of the energy business have been slow to adapt and advance to improve these circumstances. However, with the advent of the information-enabled, two-way grid, we have an opportunity to meet these challenges directly. It is the thesis of this book that through the application of big data analytics and subsequent improvements in situational awareness of the millions of miles of grid across the world, we will be able to integrate renewable energy systems, introduce economic and operating efficien- cies, and bring energy services to the over 1 billion people across the world who have no electricity. It is also the view of this work that utilities are confronted with a very difficult charge indeed—to evolve rapidly towards a business stand- point that capitalizes on these key technologies. It is going to take a resolute effort from technologists, utility stakeholders, political bodies, and energy con- sumers to protect and improve the performance of the grid, as well as affect the change necessary to shield our economies and defend the environment.
I hope to shed light on the considerable potential that big data analytics brings to the electrical power system by virtue of a fully realized analytics strategy. The unprecedented access to the immense and growing volumes of data now available to describe the electrical system and its consumers can pro- vide powerful and nearly instantaneous insight. This insight not only improves the ability to optimize day-to-day operations, but in times of stress, is the core enabler of effective decision-making and critical communications. When faced with uncertain conditions of extreme weather, terrorism, or other disasters, the safety and continuity of reliable energy delivery is without measure.
One could hardly say that the grid is broken today, but system reliability and efficiency has degraded over the past several decades. And change has been slow to come. It is imperative that, as a society, we find ways to make the grid more resilient, secure, efficient, reliable, and capable of integrating with the lives of consumers. The technical innovations inherent in big data analytics for the smart grid are the first step and the future step.

作者简介
Carol L. Stimmel began working with "big data analytics" in 1991 while hack- ing code and modeling 3D systems for meteorological research—years before that combination of words ever became buzzword compliant. In those 23 years, she has spent the last 7 focusing on the energy industry, including smart grid data analytics, microgrids, home automation, data security and privacy, smart grid standards, and renewables generation. She has participated in emerg- ing technology markets for the majority of her career, including engineering, designing new products, and providing market intelligence and analysis to utili- ties and other energy industry stakeholders.PA\Carol has owned and operated a digital forensics company, worked with cutting-edge entrepreneurial teams; co-authored a standard text on organiza- tional management, The Manager Pool; and held leadership roles with Gartner, E Source, Tendril, and Navigant Research. She is the founder and CEO of the research and consulting sustainability company, Manifest Mind, LLC, which brings rigorous, action-based insight to advanced technology projects that create and maintain healthy ecosystems for people and the environment. Carol holds a BA in Philosophy from Randolph-Macon Woman's College.
