Solar irradiance distribution under vertically mounted agrivoltaic systems – Model development, validation, and applications for microclimate assessment

Pietro Elia Campana, Jonathan Staaf Scragg, Silvia Ma Lu, et al.

Published: 2022-11-21
Subjects: Agriculture, Power and Energy

ccurate assessment of the Photosynthetically Active Radiation (PAR) and Global Horizontal Irradiance (GHI) at the crop level is paramount for accurately assessing the energy balances and the crop yield under agrivoltaic systems. The shadings produced by the photovoltaic modules and structures of the agrivoltaic systems cause a non-homogeneous distribution of PAR and GHI at the crop level. It is [...]

Meteorological Drivers of Resource Adequacy Failures in Current and High Renewable Western U.S. Power Systems

Srihari Sundar, Michael Craig, Ashley Payne, et al.

Published: 2022-08-31
Subjects: Climate, Meteorology, Power and Energy, Risk Analysis

Power system resource adequacy (RA), or its ability to continually balance supply and demand, underpins human and economic health. How meteorology affects RA, particularly with increasing penetrations of renewables, is poorly understood. We characterize large-scale circulation patterns that drive RA failures at increasing wind and solar penetrations by integrating power system and synoptic [...]

Evaluating the Economic Fairways for Hydrogen Production in Australia

Stuart Duncan Christopher Walsh, Laura Easton, Zhehan Weng, et al.

Published: 2021-05-20
Subjects: Chemical Engineering, Natural Resource Economics, Natural Resources Management and Policy, Physical and Environmental Geography, Power and Energy, Water Resource Management

Assessments of hydrogen project viability typically focus on evaluating specific sites for development, or providing generic cost-estimates that are independent of location. In reality, the success of hydrogen projects will be intimately linked to the availability of local energy resources, access to key infrastructure and water supplies, and the distance to export ports and energy markets. In [...]

Hydropower information for power system modelling: the JRC-EFAS-Hydropower dataset

Matteo De Felice

Published: 2020-10-22
Subjects: Power and Energy, Water Resource Management

Hydropower plays a very important role in European power systems. Consequently, any power system model aiming to reproduce the behaviour of current and future European power systems should include an accurate representation of the natural variability of water availability, i.e. the amount of water that can be transformed into energy. The JRC-EFAS-Hydropower dataset contains the weekly [...]

Optimising tidal range power plant operation

Athanasios Angeloudis, Stephan C Kramer, Alexandros Avdis, et al.

Published: 2017-12-11
Subjects: Civil and Environmental Engineering, Civil Engineering, Computational Engineering, Electrical and Computer Engineering, Engineering, Hydraulic Engineering, Oceanography, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics, Power and Energy

Tidal range power plants represent an attractive approach for the large-scale generation of electricity from the marine environment. Even though the tides and by extension the available energy resource are predictable, they are also variable in time. This variability poses a challenge regarding the optimal transient control of power plants. Here we consider simulation methods which include the [...]

Comparison of 0-D, 1-D and 2-D model capabilities for tidal range energy resource assessments

Athanasios Angeloudis, Matthew Piggott, Stephan C Kramer, et al.

Published: 2017-11-22
Subjects: Civil and Environmental Engineering, Computational Engineering, Earth Sciences, Electrical and Computer Engineering, Engineering, Environmental Sciences, Hydraulic Engineering, Oceanography, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics, Power and Energy

Tidal range energy projects present an attractive means for the predictable and large-scale generation of electricity from the marine environment. In particular, proposals are under consideration in UK waters, with their feasibility currently being under high levels of scrutiny. This is due to a combination of potential environmental and socio-economic impacts that are challenging to quantify in [...]
