However, the problem of suitable materials and design of the thermovoltaic element remains open. Therefore, this work is devoted to the study of the thermovoltaic effect in <i>n</i>‑GaSb, <i>n</i>-GaAs, and <i>n</i>-GaP binary compounds. The current–voltage characteristic (<i>I</i>–<i>V</i> curve) of the structures Ni–Ag–GaSb–Ag–Ni, Ni–Ag–GaAs–Ag–Ni, Ni–Ag–Sn–GaP–Sn–Ag–Ni, Ni–Ag–Si–Ag–Ni, and Au–Ni–Ag–Au are investigated in the temperature range of 300–500 K. As the temperature increased, shifts in the <i>I</i>–<i>V</i> curves of semiconductor structures are observed towards increasing voltage and current, which indicates the appearance of EMF and current during uniform heating. At 500 K, the points of intersection of the <i>I</i>–<i>V</i> curves with the voltage axis are 10.6 mV for GaP, 6.3 mV for GaSb, 5.3 mV for GaAs, and 0.9 mV for Si, as well as with the current axis, respectively 3.8 μA cm<sup>–2</sup> for GaP, 480 μA cm<sup>–2</sup> for GaSb, 184 μA cm<sup>–2</sup> for GaAs, and 2.7 μA cm<sup>–2</sup> for Si. Uniform heating of the structures under consideration in the dark leads to the occurrence of EMF and current in them.

It was mathematically modeled for drying ginger products. The solar tunnel dryer comprises of a transparent UV-stabilized plastic-coated chamber and a flat plate solar collector covered in glass. An exhaust fan with solar photovoltaic modules is provided to evacuate the moist air from the dryer. The designed dryer has length, and width area of 8.5, 2 m, and 11 m<sup>2</sup>, respectively. The average daily efficiency of the solar collector over eight hours was about 32%. The dryer can dry 50 kg of ginger per batch. The ginger has a starting moisture content of 90.4% (w.b) and the ultimate moisture level is about 11.8% (w.b). Ginger was selected because it is a major agricultural commodity in Ethiopia, where it is utilized both fresh and dried forms. The dried ginger is utilized for commercial applications. It is used as a local medication and as a flavoring spice in most families. It is quite important in the country’s traditional eating patterns. The ginger was sliced into average length of 9.5 cm, thickness of 1.5–2 mm, and a weight of 7.5–9.2 g pieces. The design improved the Cost of fuel and electricity saved per season. A non-linear regression analysis was used to develop drying models for ginger. The models were compared using the correlation coefficient (<i>R</i><sup>2</sup>), the residual sum square (RSS), and standard error of estimates (SEE) analysis to determine the one that best represented the thin layer drying characteristics of ginger.

It occurs when part of a PV system is shaded while the rest of the system is fully illuminated. Partial shading disturbs the regular shape of the power curve that has single-power peak and produces power curve with multiple power peaks. Numerous hill-climbing algorithms exist, however they usually miss the operation on the global power peak and instead get stuck in one of the local peaks resulting in power losses. This paper derives a set of simple equations estimating the power peaks of partially shaded modules which are then utilized to develop a method for global power peak tracking.

Currently in the development of large wind power plants worldwide hydraulic transmission is used to increase reliability and reduce the cost. However, the efficiency of such systems is lower than the efficiency of systems with a mechanical transmission (gearbox). But in regions with a shortage of wind power, wind power plants with a gearbox are not effective, and a hydraulic transmission could provide an increase in the Annual Energy Production of small wind power plants. Proposed is a small multi-unit wind-driven power plant with a hydraulic drive and an accumulator for power supply to remote facilities in rural areas. Methods for calculating the parameters and modes of operation of a multi-unit wind-driven power plant have been developed. The operation of a multi-unit wind-driven power plant was studied in the range of wind speeds of 4–14 m/s. The results of the theoretical analysis of the operation of the multi-unit wind-driven power plant are presented in the form of torque, rotational speed, power and flow rate diagrams. The results showed that the sum of flow rates of several pumps in the hydraulic system can provide the required constant flow rate of the hydraulic motor in a wide range of wind speeds. Thus, even at low wind speeds of 3–4 m/s on a typical day for a region with an average periodic wind speed of 4.3 m/s the total daily flow shortage is 75.2 L/min, while the total daily surplus is 180 L/min. The above calculation methods allow for a comparative analysis of the parameters, as well as the selection of design for the multi-unit wind-driven power plant being developed. The use of a hydraulic system with a hydraulic accumulator and several wind-receiving devices of different parameters, connected in parallel, significantly increases the efficiency of a small wind-driven power plant in a region with low-potential wind energy. In this case, the efficiency of the electric generator of a wind-driven power plant will always be maximum, since a constant rotational speed of the generator shaft is maintained and optimal generator modes are provided.</p>","PeriodicalId":475,"journal":{"name":"Applied Solar Energy","volume":"59 4","pages":"568 - 578"},"PeriodicalIF":1.204,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139475452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a new power electronics-based PVE is proposed to emulate the dynamic and static characteristics of the PV cell/module. The nonlinear equations of the PV cell/module are resolved using a new piecewise segmentation technique, involving the splitting of the current-voltage (<i>I–V</i>) curve into twelve linear segments associated with the letters a to m (a–m). Based on input environmental conditions, a trained artificial neural network (ANN) is constructed to assist the linearization process by predicting the current-voltage boundary coordinates of these segments. By the use of simple linear equations with the boundary coordinates, a reference voltage is then generated for the PVE. A nonlinear backstepping controller is designed to exploit the PVE reference voltage and stabilize the PCS. The stability of the controller is verified by Lyapunov laws. Optimal performance and control of the PCS were ensured by resorting to particle swarm optimization (PSO). The overall system has been investigated in the MATLAB environment with major tests including the response to fast-changing irradiance and temperature, the EN 50530 test, and the response to change in the load. The proposed PVE revealed a satisfactory dynamic performances in mimicking the PV characteristics.
