The dispersed PV generator is viewed as an active device used to improve system stability by appropriately modulating the power conditioning unit's output power. Disturbances on the utility system can be damped out by injecting this power into the grid in such a way so that the net effect is a cancellation of undesirable oscillations. The approach is implemented by monitoring the oscillating power and generating control signals which shape accordingly the interface unit's output power. Successful implementation of the scheme relies heavily on the speed and flexibility with which the electronic inverter moves power from the primary source/storage facility to the utility lines. Simulation studies, using the proposed control approach, indicate that application of these policies may result in reduced load following requirements for conventional power generating units, increase the value and acceptability of new energy technologies, and improve power quality and stability of the interconnected system.

The market for photovoltaic is rapidly expanding and there are some large utility PV power plants, thousands of residential systems, and tens of thousands of remote power systems in use. Even if photovoltaic is a technology that has already demonstrated its effectiveness and holds great promise in electrical generation, the costs are still too high to guarantee a commercial competitivity. This paper presents the performance results of a 15 kWp photovoltaic power plant installed on the roof of a high school in central Italy. The system consists of 220 modules for a total of 22 arrays, which are connected to inverters to allow conventional appliances to be powered by photovoltaic electricity. The PV plant is remotely controlled and data on sun radiation, ambient temperature, modules temperature and power production are continuously acquired by a PC. The measured power plant performances during the year are presented in this paper.Copyright © 2003 by ASME

The novelty lies in the fact to investigate the topic of irradiance enhancement. The impact of meteorological parameters on the performance of different bifacial photovoltaic module types of same cell type was determined. A cloud classification with sky imager was performed for clouds that trigger irradiance enhancements and interpretation of the underlying physical mechanisms was done. The main focus of this study was the appearance of irradiance enhancement events, the change of meteorological parameters during enhancement and the impact of these changes on the performance of photovoltaic bifacial module technologies. The analysis of efficiencies as well as yield performance was done in comparison to mono crystalline reference modules for the full year as well as only during irradiance enhancement. The impact of meteorological parameters on the performance of different bifacial photovoltaic module types was determined time resolved during irradiance enhancement as well as for a diurnal cycle in the period 04/2020–06/2021. Irradiance enhancements exceeding 1000 Wm−2 were found to occur only on days with clouds in Vienna (Austria). For 179 irradiance enhancement situations analysed, 81 % of all enhancements happened for cloudiness greater than 0.4 and still 30 % for a cloudiness greater than 0.7, the latter resulting also in single enhancement events greater than 1150 Wm−2. Cloud genera preferentially causing irradiance enhancements were identified as Altocumulus and Cumulus clouds. The mechanism of irradiance enhancement compatible to the position of the sun towards the clouds were in accordance with the cloud types Mie-scattering and edge reflections, respectively, or a mix of both. The overall photovoltaic long term performance results showed that the average weighted absolute efficiencies of the bifacial photovoltaic modules were 2–4 % higher than the ones of monofacial standard reference modules. The performance of the bifacial modules increased consistently between 17–24 % throughout the 15 month period of investigation independent of orientation with a visible seasonal variation, namely 19–28 % in winter, 18–24 % in spring, 16–25 % in summer and 17–27 % in autumn. This repository contains the pre- and post-measurement of the surface albedo (folder: Albedo), the statistical evaluation of the cloudiness index (folder: Cloud evaluation), the cloud pictures during irradiance enhancements exceeding 1015 Wm-2 (folder: Cloud pictures RE_times_1100-1015), the ambient temperature and irradiance (folder: Wheaterstation_files) and the calculated average wavelength of the solar spectrum during measurement (folder: average_wavelength). Also, the folder Biface data contains the meausrement of the module power and energy yield of the test modules.

Authors: Koami Soulemane Hayibo; Joshua M. Pearce;Koami Soulemane Hayibo; Joshua M. Pearce;To enable lower-cost building materials, a free-swinging bifacial vertical solar photovoltaic (PV) rack has been proposed, which complies with Canadian building codes and is the lowest capital-cost agrivoltaics rack. The wind force applied to the free-swinging PV, however, causes it to have varying tilt angles depending on the wind speed and direction. No energy performance model accurately describes such a system. To provide a simulation model for the free-swinging PV, where wind speed and direction govern the array tilt angle, this study builds upon the open-source System Advisor Model (SAM) using Python. After the SAM python model is validated, a geometrical analysis is performed to determine the view factors of the swinging bifacial PV, which are then used to calculate the solar irradiation incident on the front and back faces of the bifacial PV modules. The findings reveal that free-swinging PV generates 12% more energy than vertical fixed-tilt PV systems. Free-swinging PV offers the lowest capital cost and the racking levelized cost is over 30% lower than the LCOE of other agrivoltaics racks including the LCOE of commercial fixed-tilt metal racking, optimized fixed-tilt wood racking PV, and seasonally adjusted wood racking PV.

The market for photovoltaic is rapidly expanding and there are some large utility PV power plants, thousands of residential systems, and tens of thousands of remote power systems in use. Even if photovoltaic is a technology that has already demonstrated its effectiveness and holds great promise in electrical generation, the costs are still too high to guarantee a commercial competitivity. This paper presents the performance results of a 15 kWp photovoltaic power plant installed on the roof of a high school in central Italy. The system consists of 220 modules for a total of 22 arrays, which are connected to inverters to allow conventional appliances to be powered by photovoltaic electricity. The PV plant is remotely controlled and data on sun radiation, ambient temperature, modules temperature and power production are continuously acquired by a PC. The measured power plant performances during the year are presented in this paper.Copyright © 2003 by ASME

For further information contact us at helpdesk@openaire.euResearch data keyboard_double_arrow_right Dataset 2024Publisher:Mendeley Data Authors: Krainer, Diana;Krainer, Diana;This study presents the performance behavior of bifacial photovoltaic (PV) modules in comparison to monofacial standard modules. The novelty lies in the fact to investigate the topic of irradiance enhancement. The impact of meteorological parameters on the performance of different bifacial photovoltaic module types of same cell type was determined. A cloud classification with sky imager was performed for clouds that trigger irradiance enhancements and interpretation of the underlying physical mechanisms was done. The main focus of this study was the appearance of irradiance enhancement events, the change of meteorological parameters during enhancement and the impact of these changes on the performance of photovoltaic bifacial module technologies. The analysis of efficiencies as well as yield performance was done in comparison to mono crystalline reference modules for the full year as well as only during irradiance enhancement. The impact of meteorological parameters on the performance of different bifacial photovoltaic module types was determined time resolved during irradiance enhancement as well as for a diurnal cycle in the period 04/2020–06/2021. Irradiance enhancements exceeding 1000 Wm−2 were found to occur only on days with clouds in Vienna (Austria). For 179 irradiance enhancement situations analysed, 81 % of all enhancements happened for cloudiness greater than 0.4 and still 30 % for a cloudiness greater than 0.7, the latter resulting also in single enhancement events greater than 1150 Wm−2. Cloud genera preferentially causing irradiance enhancements were identified as Altocumulus and Cumulus clouds. The mechanism of irradiance enhancement compatible to the position of the sun towards the clouds were in accordance with the cloud types Mie-scattering and edge reflections, respectively, or a mix of both. The overall photovoltaic long term performance results showed that the average weighted absolute efficiencies of the bifacial photovoltaic modules were 2–4 % higher than the ones of monofacial standard reference modules. The performance of the bifacial modules increased consistently between 17–24 % throughout the 15 month period of investigation independent of orientation with a visible seasonal variation, namely 19–28 % in winter, 18–24 % in spring, 16–25 % in summer and 17–27 % in autumn. This repository contains the pre- and post-measurement of the surface albedo (folder: Albedo), the statistical evaluation of the cloudiness index (folder: Cloud evaluation), the cloud pictures during irradiance enhancements exceeding 1015 Wm-2 (folder: Cloud pictures RE_times_1100-1015), the ambient temperature and irradiance (folder: Wheaterstation_files) and the calculated average wavelength of the solar spectrum during measurement (folder: average_wavelength). Also, the folder Biface data contains the meausrement of the module power and energy yield of the test modules.

Authors: Koami Soulemane Hayibo; Joshua M. Pearce;Koami Soulemane Hayibo; Joshua M. Pearce;To enable lower-cost building materials, a free-swinging bifacial vertical solar photovoltaic (PV) rack has been proposed, which complies with Canadian building codes and is the lowest capital-cost agrivoltaics rack. The wind force applied to the free-swinging PV, however, causes it to have varying tilt angles depending on the wind speed and direction. No energy performance model accurately describes such a system. To provide a simulation model for the free-swinging PV, where wind speed and direction govern the array tilt angle, this study builds upon the open-source System Advisor Model (SAM) using Python. After the SAM python model is validated, a geometrical analysis is performed to determine the view factors of the swinging bifacial PV, which are then used to calculate the solar irradiation incident on the front and back faces of the bifacial PV modules. The findings reveal that free-swinging PV generates 12% more energy than vertical fixed-tilt PV systems. Free-swinging PV offers the lowest capital cost and the racking levelized cost is over 30% lower than the LCOE of other agrivoltaics racks including the LCOE of commercial fixed-tilt metal racking, optimized fixed-tilt wood racking PV, and seasonally adjusted wood racking PV.
