WELCOME

The advent of massive data sets and advanced analytical techniques is changing information technology in fundamental ways. In the past, data was used primarily to confirm hypotheses. Increasingly, data is used to generate

hypotheses, indicate trends, identify anomalies, and make predictions. This new paradigm is impacting research in diverse fields and business in diverse industries.

The impact is particularly great in energy and environment. This is driven by the proliferation of sensors measuring physical properties, the availability of vast networks of human data, the algorithms to extract information, and the computing power to do this in real time. This is an area where data, tools, and applications are closely linked.

This conference on big data in energy and environment showcases the latest work in four broad areas. The session on data science techniques and embedded sensors looks at the fundamental analytical tools and sources of data that enable applications. The session on oil and gas exploration and production shows how more accurate information and models are revolutionizing drilling and extraction.

The session on environment and climate change examines the role of big data in valuing natural resources and adaptation to climate change. The session on societal networks and the electric grid addresses the interdependency of social science and efficient energy management. Each of these sessions includes an innovative and exciting startup company, presented by the entrepreneurial founders.

Thanks to your support, the Energy and Environment affiliates Program is one of Stanford’s largest and fastest growing corporate affiliates programs. It spans all of Stanford University with a focus on energy, environment, materials, chemistry, and sustainability. These semi-annual meetings provide a remarkable opportunity to see cutting-edge research, meet the professors and graduate students who are doing the research, and interact with other companies.

Thank you for your participation.

Energy and environmental research is a major theme at Stanford and is found in nearly every academic discipline.

Stanford emphasizes an interdisciplinary approach, recognizing that energy and environmental research activities are interwoven within the fabric of nearly all Stanford academics.

FINDING RESEaRCH GERMaNE tO YOuR INtEREStSIt can be difficult for those outside the Stanford community to quickly grasp the

scope of energy and environment research activities on campus or to understand where specific research is being conducted in a particular area of commercial interest. Among the benefits that the Energy and Environment Affiliates Program aims to deliver to our members is assistance in understanding what specific research is taking place at Stanford, who is conducting it, and how to engage directly with those activities.

For details, visit the Affiliates Program website at eeap.stanford.edu.

Sid PatelDepartment:CivilandEnvironmental EngineeringAdvisor: Ram RajagopalPosterTitle:AggregationforLoad ServicingResearchDescription:Theproliferation of smart meters enables a load serving entity (LSE)toaggregatecustomersaccording to their consumption patterns. Patel demonstrates a method for constructing groups of customers who will be the cheapest to service at wholesalemarketprices.Usingsmart meter data from a region inCaliforniaandaggregatingmore of these customers to-gether, their consumption can be forecasted more accurately, which allows an LSE to mitigate

financial risks in its wholesale market trans-actions. Patel observes that the consumption of

aggregates of customers with similar consumption patterns can be forecasted more ac-curately than that of random aggregatesofcustomers.Themodel he proposes enables an LSE to offer discounted rates tolow-costcustomersbecauseit can purchase electricity for them more cheaply than it can for the general population.

Raffi SevlianDepartment:ElectricalEngineeringAdvisor: Ram RajagopalPosterTitle:AModelfortheEffect of Aggregation on Short TermLoadForecastingResearchDescription:Inthiswork, Sevlian proposes a simple empirical scaling law that describes load forecast-ing accuracy at different levels of aggregation. He shows that for the short term forecasting

problem, aggre-gating more users will improve the relative forecast-ing performance up to a point.

Beyond this point, no more improvement in relative perfor-mance can be obtained.

Chenguang zhuDepartment:ComputerScienceAdvisor: Balaji PrabhakarPosterTitle:CAPRI:Congestionand Parking Relief Incentives (jointposterwithChinmoyMandayam)ResearchDescription:CAPRIis a program to incentivize Stanford commuters to shift automobile commute times to off peak hours, and to take up bicycling and walking commutes.CAPRIincludesastatus system and magic boxes featuring personalized offers to encourage participation. Currently,thereareover4,500registered users, including over 850walkersandbikers.SinceApril2012,morethan550,000automobile commutes and over50,000walkingandbiking

trips have been recorded.Tobetter under-stand the impact of incentive mechanisms on

users’ commute behavior, we employ a generative user

model to classify users based on performance and character-ize the temporal dynamics of behavioralshift.Theresultsshow that our system has a siz-able impact on users’ decision to shift automobile commute times to off peak hours.

tailed, ignores the bulk of the data.Thisresearchdevelopsstatistical modeling and esti-mation approaches by combin-ing robust regression and long tailestimation.Theapproachallows Shenoy to estimate the regression model, distribution body, distribution tails, and boundaries between the body and the tails. As an application example, the model is esti-mated for historical power load data from an electrical utility. Practical usefulness of the model is illustrated by stochas-tic optimization of electricity orderinday-aheadmarket.
