This paper is an update of an earlier supply analysis, He, et al., (2013), of low-temperature utilization of geothermal resources using geothermal district heating and cooling systems. Along with the use of identified hydrothermal resources, it updates the supply curve for direct-use utilization using undiscovered hydrothermal resources and near-hydrothermal EGS resources. It also incorporates ...

The objective of this work is to investigate market power issues in bid-based hydrothermal scheduling. Initially, market power was simulated with a single stage Cournot–Nash equilibrium model. In this static model the equilibrium was calculated analytically. It was shown that the total production of N strategic agents is smaller than the least-cost solution by a factor of (N/(N +1)). Market pow...

Bi-objective problem; Hydrothermal scheduling; Economic dispatch; Emission dispatch; Combined economic emission dispatch Abstract The short-term combined economic emission hydrothermal scheduling is a bi-objective problem minimizing both fuel cost and emission of a hydrothermal system while satisfying thermal, hydro and system constraints. In this paper, an efficient cuckoo bird-inspired meta-h...

hydrothermal alteration processes are extensively took place on volcanic and pyroclstics of takestan area. existence of abundant, deep fracturing and subvolcanic intrusions are enhanced extend hydrothermal alteration zones. the following alteration zones are determined: propylitic, argillic, advanced argillic and sillicic. there are outcropped and widespread in different size and limit. formati...

[1] The nature of ridge-flank hydrothermal circulation guided by basement outcrops protruding through thick sediments is constrained on the eastern flank of the Juan de Fuca Ridge using combined bathymetric, seismic, and thermal observations and analytical and numerical calculations of coupled fluid-heat flow. Observational data near the western edge of the survey area indicate that young, cool...

the synthesis of nb doped batio3 has been investigated under microwave-hydrothermal (mh) conditions in the temperature of 150°c for only 2 h using c16h36o4ti, bah2o2.8h2o and nbcl5 as ba, ti and  nb sources, respectively.  typical experiments performed on mh processing have not yet reported for nb doped batio3.  in the mh process, the formation of high purity nano tetragonal nb-batio3 was stron...

Typically, granitic intrusions that document the lengthy and intricate history of magmatic-hydrothermal system are linked to tungsten deposits. Uncertainty persists about genetic relationship between mineralization development. The primary deposit in Dai Tu region, known as Nui Phao deposit, has been subject a petrographical microscopic examination. Tungsten area often occurs association with f...
