“…Moreover, as the natural convection heat loss was only evaluated ignoring the wind influence [47]. 4) The model was at 90 o only since this orientation achieves the lowest amount of convective heat losses [47][48]. Moreover, this position does not affect the optical analyses which were achieved in a position of -90 o [49].…”

“…In parallel, the EU-funded OMSoPproject developed a CSP plant based on parabolic dish technology that integrates in a volumetric receiver a combustion chamber, attached to a micro-Gas Turbine (mGT), obtaining a nominal electrical power output of 5-10 kWe with air outlet temperatures up to 820°C [14]. Specific designs for the solar receiver have been recently proposed and validated [15][16][17]. These small-scale hybrid CSP plants show a clear tendency to be attractive for off-grid applications in the distributed energy generation [18,19] and currently can compete against non-renewable diesel generators or photovoltaic technology.…”

Thermodynamic and Cost Analysis of a Solar Dish Power Plant in Spain Hybridized with a Micro-Gas Turbine

Small-scale hybrid parabolic dish concentrated solar power systems are a promising option to obtain distributed electricity. During the day, solar energy is used to produce electricity, and the absence of sunlight can be overwhelmed with fuel combustion. This study presents a thermo-economic survey for a hybridized power plant in different regions of Spain, considering the local climatic conditions. The developed model considers the instant solar irradiance and ambient temperature dynamically, providing an estimation of the power output, the associated fuel consumption, and the most relevant pollutant emissions linked to combustion. Hybrid and combustion-only operating modes at selected geographical locations in Spain (with different latitudes, mean solar irradiances, and meteorological conditions) are analyzed. The levelized cost of electricity indicator is estimated as a function of investment, interest rate, maintenance, and fuel consumption actual costs in Spain. Values of about 124 €/MWhe are feasible. Fuel consumption and emissions in hybrid operation can be reduced above 30% with respect to those of the same turbine working in a pure combustion mode. This model shows the potential of hybrid solar dishes to become cost-competitive against non-renewable technologies from the point of view of costs and reduction in gas emission levels in regions with high solar radiation and low water resources.

“…This process is used to self-power the low-power electronic devices; by using this process, it is possible to reduce the dependency of external power sources and batteries. The various energy sources of energy harvesting are vibration, ambient radiation, ambient light, fluid flow, thermal and solar energy [1][2][3][4][5]. Vibration is a mechanical source of energy.…”

This paper presents the performance (frequency response, open-circuit voltage, optimum load, voltage and power under optimum load) of various designs of cantilever-based piezoelectric energy harvester with multiple piezoelectric materials, which is excited at the fixed end using the source of mechanical vibration and to compare the performance with single piezoelectric-mounted energy harvester. The performance of the energy harvester was determined using experimental and numerical methods. COMSOL Multiphysics 5.3a was used to obtain the numerical results of energy harvester. The results show that inverted taper in thick and width, inverted taper in thick and inverted taper in width piezoelectric energy harvesters produce 46.15%, 13.13% and 37.70% more power than the conventional rectangular piezoelectric energy harvester. The resonant frequency of inverted taper in thick and width, inverted taper in thick and inverted taper in width energy harvesters is 52.05%, 45.5% and 11.08% lower than the conventional rectangular energy harvester. It is observed that the different beam geometries with two piezoelectric material produce more power than the beams with single piezoelectric material.
