KNO3 was used as the phase change material (PCM), but its thermal conductivity is too low to transfer heat between the PCM and conduction oil efficiently. In this thesis, on the basis of the previous studies (Yong Li, 2015), the solar power generation efficiency is enhanced with high temperature interval (280°C—400°C), and the new composite which are composed by the SiC honeycomb (SCH) frame an...

Security-constrained unit commitment SCUC is an important tool for independent system operators in the day-ahead electric power market. A serious issue arises that the energy realizability of the staircase generation schedules obtained in traditional SCUC cannot be guaranteed. This paper focuses on addressing this issue, and the basic idea is to formulate the power output of thermal units as pi...

UC (Unit Commitment) is a non-linear, large scale, complex, mixed-integer combinatorial constrained optimization problem. This paper proposes, a new hybrid approach for generating UC schedules using SI (Swarm Intelligence) learning rule based NN (Neural Network). The training data has been generated using DP (Dynamic Programming) for machines without valve point effects and using genetic algori...

This paper proposes a novel technique for solving generation scheduling and ramp rate constrained unit commitment. A modified objective function associated with a new start-up cost term is introduced in this paper. The proposed method is used to solve generating scheduling problem satisfying SRR, minimum up and down time as well as ramp rate constraints. Two case studies are conducted to imp...

Many researchers propose dedicated hardware [1, 2] to process sensor data on mobile systems, reducing the burden on generalpurpose computing units and increasing a system’s energy eciency. However, these hardware units are placed at a distance from sensors, thermally isolated to avoid an increase in thermal noise of sensors that can degrade the €delity of the sensor output signal. In this post...

this study aims to estimate economic capacity and, in turn the utilization rate of economic capacity in iran’s electricity generation industry during 1350-1388. aggregate time series data for thermal power plants are used. with parametric restrictions for linear homogeneity in input prices imposed, capital demand function is first derived and estimated. this allows the derivation of economic ca...

The physical mechanisms of entropy generation in a condenser with high fractions of noncondensable gases are examined using control volume, scaling, and boundary layer techniques, with the aim of defining a criterion for minimum entropy generation rate that is useful in engineering analyses. This process is particularly relevant in humidification-dehumidification desalination systems, where min...

the purpose of this paper is to investigate the egm method and the behavior of a solid particle suspended in a twodimensional rectangular cavity due to conjugate natural convection. a thermal lattice boltzmann bgk model is implemented to simulate the two dimensional natural convection and the particle phase was modeled using the lagrangian–lagrangian approach where the solid particles are treat...

lurestan province is petroliferous area. the reserved oil are in ilam and sarvak  (cretaceous ) and kangan ( lower triassic ) and dalan (permian) formations. the lurestan area had high exploration activity but contribution of source rocks in hydrocarbon accumulations isn’t clear. in this paper essential elements and process of hydrocarbon accumulation are introduced. candidate  source  rocks ar...
