What has been the most significant advancement in recent years in this field? And what are the biggest challenges ahead?

With smart-meter rollout, renewables and low carbon technologies, such as electric vehicles and heat pumps, individual level energy forecasts are becoming increasingly important. Furthermore, across different areas of data science applications, there is a recognition that hybrid methodologies which combine machine learning and statistical methodology can improve computation times and increase predictive power from pooling highly complex data generated by different sources. For example, combining traditional approaches to forecasting with databases encompassing social and human behaviour indicators. Hence, the challenge is responsible innovation in terms of striking the right balance between protecting privacy and data sharing in the development of future energy management approaches.


How can the research in this field help in the context of grand societal challenges?

In order to be able to manage our electric energy consumption and have a flexible, efficient and reliable energy management system we need good forecasts. This is necessary ingredient for all kinds of applications: storage control, system modelling, making business cases for low carbon technologies uptake, running different scenarios for policy development, etc.  Our research is a step in this direction.


What sets this book apart from other books?

This book is the culmination of a research project with a major player in the energy sector. It combines mathematical fundamentals, machine learning techniques and specific statistical methodology for extreme values in order to address problems of practical importance in short-term forecasts by focusing on peaks. For example, it is a first time that permutation-based distances and forecasts that allow small time-shifts between electric profiles are reviewed in a book. The application of extreme value theory to improve on time-series modelling of electricity load profiles is carried out in a truly novel setting, which makes this book one of a kind.


Why did you choose to publish this book as an open access book and what do you envisage from this publication?

We believe that electric energy efficiency is extremely important for carbon footprint reduction, so we are glad that the knowledge can be openly shared, including code and data we use in the book. We have designed and structured the book in such a way that well-separated and self-contained chapters (although with possible interconnection moderated by the particular application to peak electricity demands) can be used for teaching in class and/or in empowering students to promote independent learning.

Why the forecasting of electricity peaks is
a highly important topic?

In an era of inter-connectivity of modern society, information collection and intensive high performance computation, mass digital disruption is one of the worst scenarios that could face the energy sector. Technology has become ubiquitous and wherever you position yourself on the sliding scale from a centrally controlled energy market, through control distributed generation, towards consumer participation in energy storage (batteries), accurate and timely forecasts for peak demands are a fundamental part of any efficient energy management plan in order to avoid power shortages.
