Capacity withholding equilibrium in wholesale electricity markets
This paper is a quanرایگان!
This paper is a quantitative study of the capacity withholding incentives in the deregulated wholesale electricity markets and resulting price spikes. For the analysis we used an N-player Nash equilibrium model based on marginal cost functions of the generating firms assuming completely inelastic industry demand and complete information. The current results show that in the case of continuous marginal costs the withholding incentive always exists and the total withholding increases with the increase of the curvature of marginal cost functions and the extent of heterogeneity of the generating firms. The discrete form of real marginal cost functions imposes certain restrictions on the withholding. The analysis shows that there exists a threshold level of market demand below which no withholding occurs and above which the withholding becomes beneficial. The curvature and heterogeneity of marginal cost functions also affect the level of this threshold. The model is applied to the power generation in California ISO area.
Phase equilibrium measurements for hydrates of the CH4 /CO2 / 1, 4-Dioxane aqueous solution system
The equilibrium compرایگان!
The equilibrium compositions and properties of CO2/CH4/1,4-dioxane/water hydrate were studied for the first time at temperatures ranging from 273.65 to 281.35K and pressures ranging from 0.5 to 1.1MPa. The gas mixture consist of about 45% CO2 was used to be an exemplary for biogas and landfill gas operations. Equilibrium hydrate formation conditions for above system were measured. 1,4-Dioxane lowered equilibrium pressure by 2MPa comparing with pure water at some temperatures. This is an indication that structural transition from SI to SII was occurred
