Integrating Climate Risk into Long-Term Energy Planning: A Critical Review
Published: 2023-07-15
Subjects: Civil Engineering, Earth Sciences, Power and Energy, Risk Analysis
Electricity systems face substantial and growing climate risks which are escalating due to electrification, renewable energy intermittency, population changes, and the intensifying impacts of climate change such as extreme temperatures and weather-induced infrastructure damage. This critical review investigates climate risks to the electricity sector and scrutinizes the methodologies used to [...]
Agrivoltaic systems potentials in Sweden: a geospatial-assisted multi-criteria analysis
Published: 2023-05-04
Subjects: Power and Energy
Agrivoltaic systems represent an intelligent solution combining electricity production from solar photovoltaic technology with agricultural production and avoiding land use conflicts. Geographic Information System technologies can support the implementation and spread of agrivoltaic systems by identifying the most suitable areas using useful spatially explicit information concerning [...]
Photosynthetically Active Radiation Separation Model for High-Latitude Regions in Agrivoltaic Systems Modelling
Published: 2023-03-31
Subjects: Agriculture, Power and Energy
Photosynthetically active radiation is a key parameter for modelling the photosynthetic behaviour of plants in response to sunlight and, subsequently, for determining crop yield. Separating photosynthetically active radiation into direct and diffuse components is of significance to agrivoltaic systems, which combine solar energy conversion and agricultural farming on the same portion of land. [...]
Solar irradiance distribution under vertically mounted agrivoltaic systems – Model development, validation, and applications for microclimate assessment
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
Published: 2022-08-31
Subjects: Climate, Meteorology, Power and Energy, Risk Analysis
Power system resource adequacy (RA), or its ability to continually balance energy supply and demand, underpins human and economic health. How meteorology affects RA and RA failures, particularly with increasing penetrations of renewables, is poorly understood. We characterize large-scale circulation patterns that drive RA failures in the Western U.S. at increasing wind and solar penetrations by [...]
Evaluating the Economic Fairways for Hydrogen Production in Australia
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
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
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
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 [...]
