STABL Energy’s Post

As a part of my research on optimization and its application, I have published a paper in IEEE Xplore to show how we can leverage different optimizers for battery energy storage unit sizing considering Vehicle2Grid services. This paper was presented at the IEEE 3rd International Conference on Sustainable Energy and Future Electric Transportation (#SEFET2023). Check out the paper here: https://lnkd.in/e_aMb5f3

Energy storage systems are increasingly used to support key grid functions and are being deployed in a variety of sizes, locations, and technological formats. Predicting just how well battery-based storage systems will perform over time has been difficult due to a lack of operational experience. Operators are forced to rely on opaque proprietary methods to calculate state of health, with varying levels of confidence. EPRI’s newest innovative #patent identifies a better solution to determining battery health and longevity. EPRI’s approach allows for independent analysis of storage performance through transparent analysis of easily collected performance data, allowing the development of more accurate operational costs, maintenance practices, specifications and test procedures for future systems.

I'm thrilled to announce our latest publication, titled "Hydrogen-powered Microgrid for EV Charging Stations: Load Flow Analysis and Optimization," which was presented at the 21st L&T Conference at Effat University. Heartfelt thanks to my esteemed co-authors, Lina Muthanna, Eithar Alammari, and Sara Alashwali whose collaboration was invaluable. Additionally, I extend my gratitude to Dr. Enfel Barkat for her significant contribution and continuous support. Link to Paper: https://lnkd.in/eUCHgsW5 Abstract: This paper presents an exhaustive analysis of power flow optimization within an IEEE 33-bus microgrid system using Particle Swarm Optimization (PSO) and compares it with traditional Optimal Power Flow (OPF) methods. The PSO approach is evaluated based on its effectiveness in reducing real and reactive power losses and enhancing overall system efficiency, particularly when integrated with renewable energy sources. Our study delves into the intricacies of power system optimization, examining the system's adaptability to load variations and the integration of distributed generation. The performance metrics focus on energy conservation, operational cost, system reliability, and power quality. The results from the PSO are critically assessed against those obtained from the OPF, providing insights into the suitability and effectiveness of each optimization method for modern smart grid applications.

Recent media coverage has focused on hazardous incidents involving lithium-ion batteries in electric vehicles, renewable energy storage, and consumer electronics. However, these events require context. A new EPRI Technology Innovation Spotlight examines a series of safeguards in place but also underscores the value of continued safety advances. The spotlight also reaffirms the technology as critical for decarbonization and resilience goals. View the spotlight here: https://ow.ly/YABH50Q3515

The challenge with applying any new, transformative technology is to move boldly forward while being able to satisfy concerns such as safety and reliability in a reasonable way. Safety failures in a single product manufactured by a single company can stain the reputation of all products and all companies using the same technology. The lithium ion battery is a great example. Over the last 30 years, this technology has established itself as a clean, quiet power source for many of our everyday devices: mobile phones, laptops, earbuds, watches... It's easy to forget that the batteries are even there. The only time you notice is when you're out of charge. Big mechanical power plants and internal combustion engines come with movement, noise and powerhouse drama. They look, sound, smell and feel dangerous, and we treat them with an attendant level of caution and respect. Batteries, on the other hand, serenely deliver power in their boring, drama-free way -- and that can lead to complacency. We forget that these are little boxes packed with energy that wants to get out. In rare cases, flawed product design or errors in operation can lead batteries to catch on fire or explode. This is most common in new applications of the technology, where product developers and users may be less aware of safe operating parameters, and regulatory measures have not caught up to innovation. It's easy to feel betrayed by such failures, however rare they are. The good news is that the vast majority of lithium ion products are very safe, and the overall safety record continues to improve. At EPRI, we have been working for decades to improve the safety and reliability of battery systems in a variety of applications, including electric transportation and stationary power. We've worked with partners to develop design guidelines and best practices for preventing fires, as well as educating users and first responders on how to handle fires when they occur. Our recently released Technology Innovation Spotlight provides context for recent news reports on lithium ion fires.

While charging your electric car, flexible consumption can help the power system integrate more renewables into the power grid. It benefits supply security and a faster transition to green energy – and it can save 6-10% on your bill. "Each electric vehicle owner can save money by contributing to maintaining a stable power supply and at the same time increasing the share of green energy in our electricity consumption because it is a key service for system operators," says Associate Professor Jalal Kazempour. Along with the technology company IBM and the platform provider Spirii, which develops solutions for electric vehicle charging, a team of researchers at DTU has investigated how electric vehicle batteries can contribute while charging.

ATTENTION! In just six years, half of all cars in Denmark are expected to be electric. This shift is a significant step toward cutting CO2 emissions but also presents a huge challenge for the power grid ⚡🚗⚡ 💡Now, imagine if your electric vehicle (EV) could not only reduce emissions but also enhance grid stability! In collaboration with Spirii and IBM, researchers at DTU - Technical University of Denmark have analyzed data from 1,400 EVs to study how EV batteries can bolster the power grid via flexible consumption🔋 The technology already exists for EV chargers to provide a service known as frequency containment reserve for disturbances (FCR-D). During critical power grid situations with substantial supply-demand imbalances, chargers capable of delivering FCR-D can automatically adjust their power usage—increasing or decreasing as needed, thus quickly restoring grid balance 🌍⚡ The result? Benefits all around—for grid operators, EV driver, and the planet. Plus, flexible consumption during charging could save you 6-10% on your charging bill💰 Want to learn more about FCR and Spirii's grid balancing services?

Copenhagen + 1400 EVs = grid stability “… the more electric cars participate in the provision of FCR-D services, the more stable the power supply becomes…” 🚙🔋 We urgently need to equip ALL vehicle types (buses, trucks) with V2G technology in order to participate in the electricity and balancing markets. 🚛🚌
