“…Although this high generation also causes the highest curtailment and grid losses, changing the orientation did not lead to more useful energy. The authors also found, however, that changing the tilt angle had a higher impact on the grid than on the generation and thus suggested to lower tilt angles for more constrained grids (Laveyne et al, 2020).…”

“…Not all researchers, however, have agreed with the result that slightly west-oriented panels are the most optimal configuration. A recent study by Laveyne et al (2020) investigated the impact of the orientation of PV modules on the grid, including the effects on grid losses and PV curtailment. Their results identified that the optimal orientation is the one that maximizes the annual generated electricity (south, 35°tilt in Belgium).…”

In the context of increasing concern for anthropogenic CO2 emissions, the residential building sector still represents a major contributor to energy demand. The integration of renewable energy sources, and particularly of photovoltaic (PV) panels, is becoming an increasingly widespread solution for reducing the carbon footprint of building energy systems (BES). However, the volatility of the energy generation and its mismatch with the typical demand patterns are cause for concern, particularly from the viewpoint of the management of the power grid. This paper aims to show the influence of the orientation of photovoltaic panels in designing new BES and to provide support to the decision making process of optimal PV placing. The subject is addressed with a mixed integer linear optimization problem, with costs as objectives and the installation, tilt, and azimuth of PV panels as the main decision variables. Compared with existing BES optimization approaches reported in literature, the contribution of PV panels is modeled in more detail, including a more accurate solar irradiation model and the shading effect among panels. Compared with existing studies in PV modeling, the interaction between the PV panels and the remaining units of the BES, including the effects of optimal, scheduling is considered. The study is based on data from a residential district with 40 buildings in western Switzerland. The results confirm the relevant influence of PV panels’ azimuth and tilt on the performance of BES. Whereas south-orientation remains the most preferred choice, west-orientationed panels better match the demand when compared with east-orientationed panels. Apart from the benefits for individual buildings, an appropriate choice of orientation was shown to benefit the grid: rotating the panels 20° westwards can, together with an appropriate scheduling of the BES, reduce the peak power of the exchange with the power grid by 50% while increasing total cost by only 8.3%. Including the more detailed modeling of the PV energy generation demonstrated that assuming horizontal surfaces can lead to inaccuracies of up to 20% when calculating operating expenses and electricity generated, particularly for high levels of PV penetration.

“…Solar energy production estimates depend on the solar resource and the design of the PV plant to produce power. The output of a PV system is dependent on the amount of solar irradiance received by the active surface of the PV panels (Laveyne et al, 2020). With the reference of Li and Lam (2007), Tiwari and Dubey (2010), we propose a simple formula for calculating annual gross solar PV panels output is based on the PV plant capacity (100 MW) times the total aggregated daily GHI values at the plant location for a year.…”

Risk Manage Insurance Review

Solar energy is one of the fastest‐growing renewable energy resources globally, with solar photovoltaic (PV) technology being a promising application designed to add usable solar power to the national energy mix of several countries. The Taiwan government announced that the targeted amount of electricity generated from renewable sources shall increase to 20% of its total energy supply by 2025, in which 20 GW capacity is expected to be achieved by solar PV power. This study aims to design index‐based insurance to manage the volatility risk of solar radiation on energy production. We apply auto‐regressive integrated moving average models to predict monthly and annual energy production for a solar PV power plant in Taiwan and use the estimated results to calculate the pure premium rates for the designed insurance product. The daily data on solar irradiation are from NASA surface meteorology and solar energy, spanning 35 years from January 1984 to December 2018. The analyzed results reveal that the index‐based insurance approach can protect against the impact of insufficient solar radiation on solar PV energy production to strengthen investment security for solar PV projects.

“…In particular, parameters such as azimuth and tilt angles have been found to play indispensable roles in dispatchability and stability of solar-based energy systems, with poor positioning leading always to an under-performing system. This challenge was the focus of the study presented by Laveyne et al [108], with reference to a solar-based grid-integrated distributed power system for residential applications. Specifically, real irradiation data and parameters of an existing distribution grid were employed to investigate the effects of PV panels' inclinations and azimuth angles on power output and stability of a low-voltage residential distribution grid.…”

Impacts of Renewable Energy Resources on Effectiveness of Grid-Integrated Systems: Succinct Review of Current Challenges and Potential Solution Strategies

et al. 2020

View full text Add to dashboard Cite

This study is aimed at a succinct review of practical impacts of grid integration of renewable energy systems on effectiveness of power networks, as well as often employed state-of-the-art solution strategies. The renewable energy resources focused on include solar energy, wind energy, biomass energy and geothermal energy, as well as renewable hydrogen/fuel cells, which, although not classified purely as renewable resources, are a famous energy carrier vital for future energy sustainability. Although several world energy outlooks have suggested that the renewable resources available worldwide are sufficient to satisfy global energy needs in multiples of thousands, the different challenges often associated with practical exploitation have made this assertion an illusion to date. Thus, more research efforts are required to synthesize the nature of these challenges as well as viable solution strategies, hence, the need for this review study. First, brief overviews are provided for each of the studied renewable energy sources. Next, challenges and solution strategies associated with each of them at generation phase are discussed, with reference to power grid integration. Thereafter, challenges and common solution strategies at the grid/electrical interface are discussed for each of the renewable resources. Finally, expert opinions are provided, comprising a number of aphorisms deducible from the review study, which reveal knowledge gaps in the field and potential roadmap for future research. In particular, these opinions include the essential roles that renewable hydrogen will play in future energy systems; the need for multi-sectoral coupling, specifically by promoting electric vehicle usage and integration with renewable-based power grids; the need for cheaper energy storage devices, attainable possibly by using abandoned electric vehicle batteries for electrical storage, and by further development of advanced thermal energy storage systems (overviews of state-of-the-art thermal and electrochemical energy storage are also provided); amongst others.
