Thermoeconomic operation optimization of a coal-fired power plant
Thermoeconomic models, which combine the concept of cost in the field of economics and the concept of exergy in the field of thermodynamics, provide a possibility of optimizing complex energy-generating systems to achieve a best balance between thermodynamic efficiency and economic cost (including investment cost and operation cost). For the first time, operation optimization on a 300 MW coal-f...
متن کاملThe natural hedge of a gas-fired power plant
Electricity industries worldwide have been restructured in order to introduce competition.As a result, decisionmakers are exposed to volatile electricity prices, which are positively correlated with those of natural gas in markets with price-setting gas-fired power plants. Consequently, gas-fired plants are said to enjoy a “natural hedge.” We explore the properties of such a built-in hedge for ...
متن کاملFlexibility and Technology Choice in Gas Fired Power Plant Investments
The value of a gas fired power plant depends on the spark spread, defined as the difference between the unit price of electricity and the cost of gas. We model the spark spread using two-factor model, allowing mean-reversion in short-term variations and uncertainty in the equilibrium price to which prices revert. We analyze two types of gas plants. The first type is a base load plant, generatin...
متن کاملRadionuclide emissions from a coal-fired power plant.
Current study concerns measurement of radioactivity levels in areas surrounding a 2420 MW thermal power plant fueled predominantly by bituminous coal. The concentrations of (226)Ra, (232)Th and (40)K in onsite bottom-ash were found to be 139 Bq/kg, 108 Bq/kg and 291 Bq/kg, respectively, the levels for these radiolnuclides in soil decreasing with distance from the power plant. At the plant perim...
متن کاملShould a coal-fired power plant be replaced or retrofitted?
In a cap-and-trade system, a power plant operator can choose to operate while paying for the necessary emissions allowances, retrofit emissions controls to the plant, or replace the unit with a new plant. Allowance prices are uncertain, as are the timing and stringency of requirements for control of mercury and carbon emissions. We model the evolution of allowance prices for SO2, NOx, Hg, and C...
