Future assessment of the impact of the COVID-19 pandemic on the electricity market based on a stochastic socioeconomic model.

Appl Energy 2022 May 2;313:118848. Epub 2022 Mar 2.

Institute of Electrical Systems and Energy, Federal University of Itajuba, Itajuba, MG 37500-903, Brazil.

This paper proposes a time-series stochastic socioeconomic model for analyzing the impact of the pandemic on the regulated distribution electricity market. The proposed methodology combines the optimized tariff model (socioeconomic market model) and the random walk concept (risk assessment technique) to ensure robustness/accuracy. The model enables both a past and future analysis of the impact of the pandemic, which is essential to prepare regulatory agencies beforehand and allow enough time for the development of efficient public policies.

Power system load forecasting using mobility optimization and multi-task learning in COVID-19.

Appl Energy 2022 Mar 14;310:118303. Epub 2022 Jan 14.

Guangxi Electric Power Research Institute, Nanning 530000, China.

Affected by the new coronavirus (COVID-19) pandemic, global energy production and consumption have changed a lot. It is unknown whether conventional short-term load forecasting methods based on single-task, single-region, and conventional indicators can accurately capture the load pattern during the COVID-19 and should be carefully studied. In this paper, we make the following contributions: 1) A mobility-optimized load forecasting method based on multi-task learning and long short-term memory network is innovatively proposed to alleviate the impact of the COVID-19 on short-term load forecasting.

Evaluating long-term emission impacts of large-scale electric vehicle deployment in the US using a human-Earth systems model.

Appl Energy 2021 Oct;300:1-117364

Office of Research and Development, U.S. Environmental Protection Agency, Research Triangle Park, NC, USA.

While large-scale adoption of electric vehicles (EVs) globally would reduce carbon dioxide (CO) and traditional air pollutant emissions from the transportation sector, emissions from the electric sector, refineries, and potentially other sources would change in response. Here, a multi-sector human-Earth systems model is used to evaluate the net long-term emission implications of large-scale EV adoption in the US over widely differing pathways of the evolution of the electric sector. Our results indicate that high EV adoption would decrease net CO emissions through 2050, even for a scenario where all electric sector capacity additions through 2050 are fossil fuel technologies.

Workgroup for Economic and Infrastructure Policy, Technische Universität Berlin, Straße des 17, Juni 135, 10623 Berlin, Secretariat H33, Germany.

This paper examines medium and long-term perspectives for global steam coal production and trade, considering the potential impacts of the COVID-19 pandemic and plausible recovery scenarios in its aftermath. We use an interdisciplinary approach to develop a range of stylized global coal demand scenarios until 2040 depicting the influence of the COVID-19 pandemic and resulting recovery stimuli. Additional insights are gained by adjusting trade restrictions of key countries within the coal sector model COALMOD-World to resemble plausible post-COVID-19 policy and market dynamics. Read More

A fresh (air) look at ventilation for COVID-19: Estimating the global energy savings potential of coupling natural ventilation with novel radiant cooling strategies.

Appl Energy 2021 Jun 22;292:116848. Epub 2021 Mar 22.

Princeton University, Princeton, NJ, USA.

Radiant cooling-assisted natural ventilation is an innovative technical approach that combines new radiant cooling technology with natural ventilation to increase fresh air delivery into buildings year-round with minimal energy cost and improvment of air quality. Currently, the standard paradigm for HVAC (heating, ventilation and air conditioning) is based on central air systems that tie the delivery of heating and cooling to the delivery of fresh air. To prevent heat loss, the delivery of fresh air must be tightly controlled and is often limited through recirculation of already heated or cooled air. Read More
