Urban growth compromises open space and ecosystem functions. To mitigate the negative effects, some agencies use reserve selection models to identify conservation sites for purchase or retention. Existing models assume that conservation has no impact on nearby land prices. We propose a new integer program that relaxes this assumption via adaptive cost-coefficients. Our model accounts for the tw...

A rapidly growing amount of small-scale distributed energy resources (DERs) integrated into distribution systems call for an effective electricity market to manage the uncertainty DERs and remove barriers participation in wholesale markets. To this end, paper proposes uncertainty-aware locational marginal pricing (DLMP) mechanism based on robust optimization day-ahead markets within a transmiss...
With increasing distributed energy resources (DERs) integration, the strategic behavior of a DER aggregator in electricity markets will significantly affect secure operation distribution system. In this paper, interactions among aggregator, and reserve markets, system are investigated through single-leader-multi-follower Stackelberg game model with as leader independent operator followers. To g...
The cost-efficient integration of variable renewable power (vRES) requires adequate operating reserve and energy markets. This paper focusses on the benefits increasing temporal granularity joint energy-operating markets in a case study two high-vRES systems. Specifically, impact frequency (i.e., how often reserves are sized procured) resolution or contract duration length sizing procurement bl...
For historical reasons, the frequency of Electric Railway Power System (ERPS) in central European countries (e.g., Switzerland, Germany and Austria) is different from the frequency of the public power grid. To feed such a low frequency (i.e., 16.7 Hz) system, Electric Railway Companies (ERCs) operate their own low frequency generators. Moreover, ERPSs are connected to the public power grids thr...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
This paper analyzes the role of bank competition on the life-cycle dynamics of non-financial industries. Using multi-dimensional data sets, which contain information on job creation and destruction for establishments in U.S. manufacturing sectors operating in different geographical regions and over time, I find evidence that bank competition accelerates the expansion of start-ups and helps them...
With the wide deployment of renewable energies, future power grids become more vulnerable to extreme environments. This paper investigates enhancing resilience systems with high penetrations energies under emergencies. The enhancement firstly is defined as maintaining much electric energy critical loads in a fixed number post-disaster periods by properly coordinating available resources. Then, ...
The paper presents a unit commitment model, based on mixed integer linear programming, capable of assessing the impact of electric vehicles (EV) on provision of ancillary services in power systems with high share of renewable energy sources (RES). The analyses show how role of different conventional units changes with integration of variable and uncertain RES and how introducing a flexible sour...
