Revolutionizing urban energy: how advanced EV charging schedules enhance grid efficiency
2024-06-04
(Press-News.org)
In response to the escalating demand for sustainable transportation solutions, researchers from the National Institute of Technology Silchar have developed a groundbreaking scheduling system for electric vehicles (EVs) that enhances power grid efficiency and accommodates the growing influx of solar energy. This advanced system, outlined in a recent study by Pritam Das and Partha Kayal, focuses on optimizing the charging and discharging times of EVs to better integrate with photovoltaic (PV) energy sources.
The innovative approach involves a two-stage algorithm that not only schedules EV charging sessions but also strategically manages the distribution of these sessions across various charging stations. This method aims to reduce energy loss, prevent power outages, and minimize the impact of EV charging on the power grid.
The first stage of the algorithm identifies the optimal times for EVs to charge or discharge based on the availability of solar energy, which is predicted using a cutting-edge hybrid SARIMA-LSTM model. This model accurately forecasts solar power availability, ensuring that EV charging demands coincide with peak solar energy production times. The synchronization of EV charging with solar energy peaks allows for a more efficient use of renewable resources, reducing reliance on non-renewable power sources.
In the second stage, the scheduling system allocates specific charging slots to different stations in a manner that balances the load on the electrical grid. By distributing the charging demand more evenly, the system helps maintain grid stability and prevents the typical peaks and troughs associated with unmanaged EV charging.
The benefits of this innovative scheduling system were demonstrated through extensive simulations on a 28-bus Indian power distribution network enhanced with solar energy. The results showed a significant improvement in the grid's peak-to-average load ratio, a key indicator of power grid efficiency. Additionally, the system's ability to reduce total energy consumption and enhance voltage stability was clearly evidenced in various test scenarios.
This breakthrough represents a major step forward in the integration of renewable energy and electric vehicles into urban infrastructure. By optimizing the timing and distribution of EV charging, the system not only supports the expansion of electric vehicle usage but also contributes to the overall sustainability of urban transportation.
As cities around the world continue to grow and seek environmentally friendly solutions to transportation and energy challenges, the adoption of such intelligent scheduling systems could play a crucial role in shaping a more sustainable and efficient future. The study's findings offer valuable insights for policymakers, utility companies, and consumers looking to navigate the complexities of energy management in increasingly congested urban environments.

OAK BROOK, Ill. – Using artificial intelligence (AI), breast radiologists in Denmark have improved breast cancer screening performance and reduced the rate of false-positive findings. Results of the study were published today in Radiology, a journal of the Radiological Society of North America (RSNA).
Mammography successfully reduces breast cancer mortality, but also carries the risk of false-positive findings. In recent years, researchers have studied the use of AI systems in screening.
“We believe AI has the potential to improve screening performance,” said Andreas D. Lauritzen, Ph.D., a post-doctoral student at the University of Copenhagen and researcher ...

A new study by Carnegie Mellon University researchers found that when roboticists and people with disabilities collaborate on robot designs, interesting ideas emerge that could make existing robots more accessible and inspire new uses.
In their research, School of Computer Science faculty members Sarah Fox and Nikolas Martelaro highlight potential issues sidewalk robots encounter during deployment and propose solutions to mitigate them before the robots hit the streets. Their new study, led by Human-Computer Interaction Institute (HCII) Ph.D. student Howard Han, was presented last month at the ACM Conference on ...

A new study by Florida Atlantic University’s Schmidt College of Medicine has uncovered a disturbing trend in drug-related infant deaths in the United States from 2018 to 2022.
Infant deaths are those that occur between the time a child is born and age 1. Drug-involved deaths are those in which drugs are either the primary cause of death or a contributing factor and may occur due to maternal drug use, inadvertent or accidental intake of specific prescriptions, illicit or non-medical use of drugs and other incidents where drugs were linked to death.
Results of the study, published in the Journal of Perinatal Medicine, show that in the U.S. from 2018 to 2022, drug-involved ...

Scientists at Duke-NUS Medical School have identified how the first domino falls after a person encounters an allergen, such as peanuts, shellfish, pollen or dust mites. Their discovery, published in the April issue of Nature Immunology, could herald the development of drugs to prevent these severe reactions.
It is well established that when mast cells, a type of immune cell, mistake a harmless substance, such as peanuts or dust mites, as a threat, they release an immediate first wave of bioactive chemicals against the perceived threat. When mast cells, which reside under the skin, around blood vessels and in the linings of the airways and the gastrointestinal tract, simultaneously release ...

As sad as it is, child maltreatment continues to be a prevalent global social issue. Recent studies have revealed that up to one billion children aged two to 17 experience some form of abuse or neglect every year. While it is possible that some children may eventually overcome these experiences, abundant evidence indicates that child abuse can continue to have a lasting negative impact on brain and mental development, even as these children age. Therefore, prioritizing the prevention of this menacing behavior is crucial.
One way to pursue this goal is to focus on the underlying causes that lead to the perpetuation of abuse, ...

SAN FRANCISCO—June 4, 2024—In recent years, technologies that allow scientists to study a person’s DNA at single-molecule resolution have vastly expanded our knowledge of the human genome, the microbiome, and the genetic basis of disease. With such a detailed view of DNA, it’s possible to see genetic variants and structural details that were simply undetectable with earlier sequencing technologies.
However, today’s gold-standard methods for single-molecule analysis typically require at least 150,000 human cells—containing millions of individual DNA molecules. That means researchers can’t apply these tools when just ...

DALLAS, June 4, 2024 — Significant barriers prevent or slow treatment for many patients with stroke, including long travel times to stroke center hospitals and the lack of availability of stroke specialists who can evaluate the patient and determine if they are a candidate for treatment.[1] Telehealth stroke care, also known as telestroke, can expand access to rural areas and other communities that face barriers to stroke care.
A new American Heart Association certification for health care professionals is designed to help standardize training and increase skills and competencies for health care providers ...

Electron transfer (ET) is a process in which an electron is transferred from one atom or molecule to another. ET is fundamental to electrochemical reactions with applications in many fields. Nanoscale ET, which involves the transfer of electrons in the range of 1–100 nanometers in solids is fundamental to the design of multifunctional materials. However, this process is not yet clearly understood.
Nanotubes, nanomaterials with unique cylindrical nanostructures, offer a variety of ET properties that can be realized through electron and hole (vacant spaces left by electrons) injections into the nanotubes, making them a suitable candidate for studying nanoscale ET. Although ...

While mentally stimulating activities and life experiences can improve cognition in memory clinic patients, stress undermines this beneficial relationship. This is according to a new study from Karolinska Institutet published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.
Researchers in the late 1980s found that some individuals who showed no apparent symptoms of dementia during their lifetime had brain changes consistent with an advanced stage of Alzheimer’s disease. It has since been postulated that so-called ...
