in this research, industrial wastewater treatment plants (iwwtps) were investigated and categorized by effluent applications and electrical energy cost. for the purpose of this research, 51 plants were assessed and results indicate that 17 plants discharged the effluent directly to the surface water that most of them are located in north of iran, 24 plants used the effluent for irrigation. othe...

As climate concerns, low natural gas prices, and renewable technologies increase the electric power sector’s dependence on natural gas-fired power plants, operational and investment models for gas and electric power systems will need to treat the interdependencies between these two systems to accurately capture the impacts of one on the other. Currently, few hybrid gas-electricity models exist....

The U.S. is at war in the Middle East at least in part to protect its foreign oil interests. And as China, India and other nations rapidly increase their demand for fossil fuels, future fighting over energy looms large. In the meantime, power plants that burn coal, oil and natural gas, as well as vehicles everywhere, continue to pour millions of tons of pollutants and greenhouse gases into the ...

4 We present an optimal control model that captures spatiotemporal interactions between gas 5 and electric transmission networks. We use the model to study flexibility and economic oppor6 tunities provided by coordination. A case study in the Illinois system reveals that coordination 7 enables the delivery of significantly larger amounts of natural gas to the power grid. In particular, 8 under ...

We analyze investments in gas fired power plants under stochastic electricity and gas prices. A simple but realistic two-factor model is used for price processes, enabling analysis of the value of operating flexibility, the opportunity to abandon the capital equipment, as well as finding thresholds for energy prices for which it is optimal to enter into the investment. Our case study, using rea...

Coal has long been the major fossil fuel used to produce electricity. However, coal-fired electric power plants are one of the largest sources of air pollution in the United States, with greenhouse gas (GHG) emissions from burning of fossil fuels believed to be the major contributor to global climate change. Regulations under development at the Environmental Protection Agency (EPA) would impose...
