This paper presents new solution methods and results based on a refined binary particle swarm optimization (RBPSO) for solving the generation/pumping scheduling problem within the power system operation with pumped-storage units. The proposed RBPSO approach combines a basic particle swarm optimization (PSO) with binary encoding/decoding techniques. Complete solution algorithms and encoding/deco...

A two-dimensional transient axi-symmetric model was developed to study the effects of various thermal and geometric parameters on cyclic heating and cooling modes of a phase-change thermal energy storage system. The high-temperature thermal energy storage device utilizes LiH for heat sink applications to store the waste heat generated during power-burst periods. The stored heat is then discharg...

This paper studies the influence of material thermal properties on charging dynamics in a low temperature Thermal Energy Storage, which combines sensible and latent heat. The analysis is based small scale packed bed with encapsulated PCMs, numerically solved using COMSOL Multiphysics. PCMs studied are materials constructed typical (melting temperature, density, specific heat capacity (solid liq...

To realize the lagging behavior in heat conduction observed in these two decades, this paper firstly theoretically excludes the possibility that the underlying thermal inertia is a result of the time delay in heat diffusion. Instead, we verify in experiments the electro-thermal analogy, wherein the thermal inertial is parameterized by thermal inductance that formulates hyperbolic heat-conductio...

In order to improve the availability of solar energy, this paper introduces a new solar energy storage device and its parameters automatic measuring system. The device puts the heat which was gathered by synchronous tracking solar collector into underground concrete storage pile. Meanwhile, the system could simultaneously measure the temperature, pressure and flow of the device, etc. Some deriv...

DESCRIPTION Concentrating Solar Power (CSP), also referred to as solar thermal power, uses mirrors to concentrate the sun's rays to heat a fluid that is then used to generate electricity, often using conventional steam turbines. There are three primary CSP technologies: parabolic trough, solar tower, and dish engine. The most common CSP system is the parabolic trough, which uses curved mirrors ...

In this study, we discussed the effects on the thermal comfort of super high-rise residences that how effected by the high thermal capacity structural components. We considered different building orientations, structures, and insulation methods. We used the dynamic simulation software THERB (simulation of the thermal environment of residential buildings). It can estimate the temperature, humidi...
