1 - Electricity Resource Capacity Expansion With Distributed Energy

Resources: A New MILP Formulation

Jesse D Jenkins, PhD Candidate, Massachusetts Institute of

Technology, Cambridge, MA, 02139, United States,

jessedj@mit.edu

Conventional electricity capacity expansion models do not properly consider

distributed energy resources (DERs), including distributed generation, storage and

demand response. DERs provide locational benefits—e.g. loss mitigation,

congestion relief, network capacity deferral—which must be considered along

with the costs of different unit scales. In this new MILP formulation, conventional

generation and DER investments are made across several transmission zones and

distribution voltage levels subject to power flow constraints, network

reinforcement costs, losses, and operational constraints capturing reserves, ramp

rates, and unit commitment constraints for thermal generators.

2 - Price Projections For Ancillary Services Markets Under

Hypothetical Future Scenarios

Laboratory, 9700 S. Cass Ave, Bldg 362, Lemont, IL, 60439,

We forecast broad future ancillary service price trends in U.S. power markets by

first identifying a set of key parameters that influence prices. Baseline models are

then developed and calibrated based on historical data and current regional

characteristics. We then utilize AURORAxmp to model hourly dispatch in each

region and forecast the impact of changes in these inputs, such as electricity

demand, fuel prices, renewable penetration levels, and availability of AS supply.

Finally, we identify correlations to broadly project price trends under hypothetical

future scenarios, e.g. increased wind penetration, decreased natural gas prices,

and increased supply of flexible generation resources.

3 - An Efficient Integer L-shaped Method For A Two-stage

Self-healing Power Grid Problem

Wei Sun, Qipeng Zheng

When a power system enters an emergency state, the self-healing process is

initiated by system operators to bring the system back to its normal condition.

This presentation proposes a two-stage self-healing optimization problem with a

set of practical constraints containing integer variables in both stages. To solve the

proposed problem, the integer L-shaped algorithm together with an efficient

optimality cut based on the physical characteristics of power system will be

presented. Standard IEEE test system is used to demonstrate the effectiveness of

the proposed algorithm and optimality cut.

This presentation will describe a new improved interval unit commitment

formulation that combines some aspects of stochastic and interval formulations.

A systematic and rigorous assessment of the cost and reliability performance of

the improved interval, interval, stochastic and robust unit commitment will be

demonstrated as well.

5 - Price Instability In Multi-unit Auctions

Economics (IFN), Grevgatan 34, Stockholm, SE10215, Sweden,

Edward James Anderson

We consider a uniform-price procurement auction with indivisible units and

private costs. We solve for a Bayesian Nash equilibrium and show that the

equilibrium has a price instability in the sense that a minor change in a supplier’s

realized cost can result in a drastic change in the market price. The price

instability is reduced as the size of indivisible units decreases for a given total

production capacity. In the limit, where the size of units approaches zero and

costs are almost surely common knowledge, the Bayesian equilibrium converges

to a pure-strategy NE without price instability, the Supply Function Equilibrium

(SFE).

1 - Strategic Design For Delivery With Drones And Trucks

Our research develops continuous approximation models for the strategic design

of drone and hybrid truck-drone delivery systems. We consider aerial and

ground-based drones that can be launched from fixed or relocatable facilities, or

from trucks. In contrast to discrete VRP-based optimization models, we treat the

demand for deliveries as a continuous spatial density over a region. Analytical

results and illustrations assess the economic and service performance from using

the best mix of drones and trucks, and provide strategic managerial insights.

Results show how using drones in conjunction with trucks alters the optimal

delivery strategy and can facilitate lower cost and faster deliveries.

2 - A Quantitative Model For Truck Parking And Hours Of

Service Regulations

Sarah G Nurre, University of Arkansas, 425 W. Louise Street,

Fayetteville, AR, 72701, United States,

snurre@uark.edu

Truck parking and hours-of-service (HOS) regulations are consistently reported as

two of the top concerns in the trucking industry. Parking shortages are a function

of inadequate capacity and changes to HOS regulations requiring drivers to stop

frequently and for longer periods. We develop a network-based optimization

model which determines the best times and locations for stopping along a set of

truck routes while adhering to system-wide HOS regulations, network, and

scheduling constraints. We present the results and insights deduced from

experiments run using historical truck route data.

1 - Bike Route Choice Modeling Without Choice Sets Of Paths:

Estimation, Prediction And Accessibility Measure

Maelle Zimmermann, Université de Montreal,

maelle.zimmermann@gmail.com

We estimate a link-based bike route choice model in a real network which does

not require to sample any choice set of paths, similar to the recursive logit (RL)

model formulated by Fosgerau (2013). We provide numerical estimation results,

and we show the advantages of this approach in the context of prediction by

focusing on two applications of the model: i) simulation of bike traffic flows; ii)

measuring bike accessibility. Compared to the path-based approach which

requires to generate choice sets, the RL model proves to make significant gains in

computational time and to avoid paradoxical results discussed in previous works,

e.g. in Nassir (2014).

2 - A Random Utility Based Estimation Framework For The

Household Activity Pattern Problem

Zhiheng Xu, University at Buffalo, Buffalo, NY, United States,

, Jee Eun Kang, Roger Chen

We develop an estimation framework for the Household Activity Pattern Problem

(HAPP) based on random utility theory. The estimation procedure is based on the

realization that travelers’ complex activity-travel pattern decisions form a

continuous path in space-time. The proposed framework is comprised of choice

set generation, choice set individualization, and multinomial logit estimation

procedures.

Simulator And Pc-based Experiments

We study drivers’ route choice behavior with real-time traffic information based

on driving simulator and PC-based experiments. A looking-ahead route choice

refers to a decision taking into account future diversion possibilities at

downstream nodes based on real-time information not yet available at the time of
