Conejo, The Ohio State University, Columbus, OH, 43210, United States 1 - A Combined Repair Crew Dispatch Problem for Resilient Electric and Natural Gas System Considering Reconfiguration and DG Islanding Zhengshuo Li, Southern Methodist University, Dallas, TX, USA Jianhui Wang, Yanling Lin, Bo Chen, Zhaohong Bie Resilience is an overarching concept that requires combined efforts from interdependent critical infrastructures to achieve. We present a combined repair crew dispatch problem for interdependent electric and natural gas systems. The repair schedule of the two system is coordinated and co-optimized. Both electric system topology reconfiguration and intentional DG islanding are modeled as operational measures to further improve the resilience of interdependent systems. Case studies validate the effectiveness of the proposed method in reducing load shedding and repair duration, and prove that the interdependence has a significant impact on the repair sequence and crew coordination. 2 - Equilibrium of Interdependent Gas and Electricity Markets with Marginal Price Based Bilateral Trading Wei Zheng, Tsinghua University, Beijing, China This paper studies the marginal price based bilateral energy trading on the equilibrium of coupled natural gas and electricity distribution markets. Convex relaxation is employed to solve a optimal power flow problem. A successive second-order cone programming (SOCP) approach is utilized to solve a optimal gas flow problem. In both problems, locational marginal energy prices are recovered from the Lagrangian multipliers associated with nodal balancing equations. Furthermore, a best-response decomposition algorithm is developed to identify the equilibrium of the coupled energy markets with bilateral gas and electricity trading, which leverages the computational superiority of SOCPs. 3 - Expansion Planning of Joint Electricity and Gas Networks Pascal Van Hentenryck, University of Michigan, 1813 IOE Building, 1205 Beal Avenue, Ann Arbor, MI, 48108-2117, United States, Russell Bent, Seth Blumsack Recent trends in gas-fired power plant installation has increased the connections between the electric power and natural gas industries. Despite these dependencies, both industries must meet commercial, political, operational and technical requirements that often force the industries to plan and operate in isolation. As a result, undesired situations may arise, such as those experienced by both systems during the winter of 2013/2014 in the northeastern United States. This paper, we consider the technical challenges and present a combined electricity and gas expansion planning model. 4 - Unit Commitment of Integrated Electric and Gas Systems with an Enhanced SOC Gas Flow Model Ramteen Sioshansi, Ohio State University, Integrated Systems Engineering, 1971 Neil Avenue, Columbus, OH, 43210, United States, Antonio J. Conejo, Sheng Chen Interdependent electric power and gas systems require a coordinated operation framework. This presentation proposes such framework in a form of a unit commitment (UC) model. A second-order cone (SOC) dynamic gas flow model is employed within an UC model, which results in a mixed-integer SOC programming problem. This model is enhanced by using convex envelopes of bilinear terms to tighten the UC solution. Numerical results from two test systems validate the advantages of the proposed enhanced SOC methodology in terms of solution quality and computational efficiency.

In the presence of imperfect monitoring, waste can be misclassified to hide its true nature or it can be illegally dumped to avoid expensive treatment cost. This paper examines firms’ behaviour and non-compliance when they operate under incomplete information with respect to the other agents in the chain. Further, we underscore how increased monitoring of trade bans whilst ignoring the impact of incomplete information on firms’ behaviour can have unintended consequences on the export of waste the ban was not even intended for. 2 - The Effective Mobile Phone Producers Green Supply Chain Management Practices in Reducing Co2 Emissions Yazan Migdadi, Associate Professor, Qatar University, Doha, 2713, Qatar The purpose of this study is reporting the effective mobile phone producers green supply chain management practices to reduce CO2 emissions. Quantitative case study methodology was adopted. This study identified a combination of high impact actions in reducing CO2 emissions related to green purchasing, green production, green distribution, green customers’ practices, green business travels, green facilities and offices design actions 3 - The Influences of Public Environmentalism on Air Pollutant Emissions: A Multilevel Analysis across Chinese Prefecture-level Cities Public environmentalism is an effective pollution supervision regulation to moderate pollution emissions, especially when the government has deployed accountability for environmental performance. To what extent will public environmentalism attenuate the effects of economic factors on environmental pollution? We estimate the role of public concern on pollution across 285 Chinese cities over 2004 to 2015 based on the hierarchical structure. The empirical results indicate an inverse U relationship, and public concern over environment can make the cities reach the turning points at a low GDP level. This result has important policy implicates to moderate pollution emissions. n WB46 North Bldg 228B Optimal Design and Dispatch of Alternative Energy Systems Sponsored: Energy, Natural Res & the Environment/Energy Sponsored Session Chair: Alexandra M. Newman, Colorado School of Mines, Golden, CO, 80401, United States 1 - Sub-hourly Dispatch Optimization of Photovoltaic and Concentrating Solar Power Hybrid Systems William T. Hamilton, MS, Colorado School of Mines, Golden, CO, 80401, United States, Alexandra M. Newman, Robert Braun Concentrating solar power (CSP) technologies capture thermal radiation from the sun utilizing a field of solar-tracking heliostats. When paired with inexpensive thermal energy storage (TES), CSP technologies can dispatch electricity during peak-market-priced hours. The hybridization of photovoltaic (PV) and CSP with TES systems has the potential to provide continuous energy production at a lower cost than a PV or CSP system alone. To evaluate a PV-CSP hybrid design, we develop a profit-maximizing mixed-integer linear program that determines a dispatch schedule. We present preliminary results from such model with an emphasis on parametric analysis of system design decisions.
