1 - The Case for Distributed Energy in the Developing World
Todd Levin, Energy Systems Engineer, Argonne National
Laboratory, 9700 S Cass Ave, Lemont, IL, 60439,
United States of America, , Valerie Thomas
In developing countries where infrastructure is underdeveloped, there may be
potential for decentralized technologies to leapfrog the centralized electrification
model. We present a service based economic analysis that incorporates the true,
unsubsidized cost of energy access in rural regions. We show that distributed
options may be cost-effective if consumption is modest and suggest that some grid
subsides may be more effectively channeled to support distributed approaches to
energy access.
2 - Risk-aware Control of Solar Micro-grids

Providing power to widely spread out communities using the conventional power
grid is not economically feasible. The most attractive alternative source of
affordable energy for these communities is solar micro-grids. We discuss risk-
aware robust methods to optimally size and operate micro-grids in the presence of
uncertain demand and uncertain generation. These algorithms help system
operators to increase their revenue while making their systems more resilient to
inclement weather conditions.

Carbon Abatement

This study examines how the perceived operational impacts from reducing carbon
emissions are associated with long-term investment in environmental technology
portfolios. We examine our hypotheses based on recent carbon disclosure data.
2 - Evaluating Alternative Strategies for Fostering Responsibility
Among Suppliers

Fang Liu, S Viswanathan
We look at global supply chains which comprise suppliers of varying degrees of
responsibility. In order to promote responsibility in such supply chains, global
buyers generally follow a strategy of dual investment in supplier responsibility
audit and supplier improvement. We evaluate the relative profitability of these
strategies under different scenarios. We also analyze how the buyer’s optimal
investment policy affects supply chain responsibility.
3 - A Bilevel Optimization Model for Bioenergy Contract
Price Determination

We study farmers crop selection problem in the face of crop price uncertainty,
yield uncertainty, and environmental concerns. We then propose a bilevel
optimization to help bioenergy companies determine appropriate contract prices
to encourage farmers to switch from conventional crops to energy crops.
4 - Net-zero Carbon Manufacturing and Supply Chain Operations: A
Fantasy or a Possibility?
Tongdan Jin, Texas State University, 601 University Drive,

We address two fundamental questions confronted by manufacturing and supply
chain design: 1) is it cost-effective to deploy onsite wind and solar power to
achieve net-zero carbon environmental performance? and 2) how to design a
reliable onsite energy system to meet the variable demand without storage
devices? We conclude that zero carbon operations are achievable at affordable
cost provided the local wind speed is above 5 m/s or the overcast days are less
than 35% of a year.

We test and design heuristics and an optimal decision model for introducing new
strategies to design energy supply network. A main contribution is that well-
formulated energy supply network can explain how to ensure energy supply and
energy security. We consider all of possible T&D technology such as HVAC/HADC
together, and we found that a design of energy supply network may cause an
inefficient supply of electricity unless it is optimized with an integrated network.
2 - Expected Value and Chance Constrained Stochastic Unit
Commitment Ensuring Wind Power Utilization
Chaoyue Zhao, Oklahoma State University, 322G Engineering
North, Stillwater, OK, United States of America,
In this talk, we propose an expected value and chance constrained stochastic
optimization approach for the unit commitment problem with uncertain wind
power output. A combined SAA framework that considers both the expected
value and the chance constraints is proposed to construct statistical upper and
lower bounds for the optimization problem. Finally,a revised IEEE 118-bus system
is studied to show the scalability of the proposed model and algorithm.
3 - Energy Supply Chain: Future Energy Security

Management Science, Suleman Dawood School of Business,

Electricity crisis is a major hindrance towards economic growth of Pakistan and
poses a serious national security threat to the country. The crisis has resulted into
political turmoil and social instability. We have provided a framework to address
energy supply chain design. The study shows great potential and provide
guidelines to ensure future energy security of Pakistan.
4 - Data-Oriented Decision Making in Demand Response
Weiwei Chen, Assistant Professor, Rutgers University, Rutgers
Business School, Newark, NJ, 07102, United States of America,
Demand response (DR) programs have emerged among electric utilities to reduce
peak electricity demand and enhance customer satisfaction. A critical issue is to
accurately estimate the customers’ baseline power consumptions and the load
reduction. A cohort based approach is introduced to improve the estimation
accuracy utilizing customer historic data. Then, methods to manage various DR
events considering exogenous information are developed to optimize the
expected savings for utility companies.
