2023 Journal Impact Factor. Here is a list of Energy storage materials and battery-related journals (Source: https://lnkd.in/gPTi9FHF)

Happy to share that my first journal paper has been published in Applied Energy. The article, titled 'Applicability of a flow-based grid representation in spatially resolved generation expansion planning models', builds on the work I did for my Master’s thesis. In this paper, we focus on improving the accuracy of long-term energy planning models, while maintaining computational tractability.

On May 22 ,2024 my paper titled Elevating energy storage: High-entropy materials take center stage pubished in Journal of Energy Storage (If=9.4 Scopus) Link to Paper is attached here https://lnkd.in/gGdiArTU

A new paper titled "Prosumer energy management under controllable power transactions with the grid", published by the IEEE Industry Applications Society and specifically in IEEE Transactions on Industry Applications, out of the work done in the Power and Energy Systems Laboratory - UOWM, sheds light into the often conflicting objectives of prosumers and DSOs. The work proposes a methodology for Energy Management Systems of prosumers, to both minimize the prosumer's electricity cost and reduce imported and exported power peaks. This is a work mainly by PhD Candidate Nikolaos Kelepouris, using also results from the final year Thesis of Dimitris Kelepouris in the Department of Electrical & Computer Engineering of University of Western Macedonia, Greece, with substantial contributions from my colleague Aggelos Bouhouras.

All countries looking to increase their renewable penetration will be aware of the effect that will have on inertia and therefore reduced network stability. This whitepaper looks at the Australian National Electricity Market (NEM) and the continuous measuring of inertia (not estimating it). This can facilitate the optimization of operations in transmission networks, not just saving money but reducing renewable energy curtailment.

We are thrilled to announce the release of our latest whitepaper co-authored with the University of Melbourne, shedding light on inertia measurement challenges in modern power grids. 📝 In this comprehensive study, we delve into the complexities of accurately measuring inertia in grids rich with #renewables, exploring the impact of fast controllers on traditional measurement methods. As renewable energy sources continue to reshape the energy landscape, it's crucial to understand how these changes affect #gridstability. Our paper highlights the shift from traditional passive approaches to real-time measurement and how real-time data becomes a pressing necessity once renewables surpass 30% of annual output ⚙️ We extend our heartfelt gratitude to Duncan Burt and Professor Pierluigi Mancarella for their invaluable contributions to this paper. Read the full whitepaper below to discover how accurate inertia measurement plays a crucial role in the seamless integration of renewables into the grid.

Why do Reactive use 'active' ultracapacitors and batteries to measure inertia? The answer is in this new white paper! Turns out that the use of fast controllers in low inertia power systems means that 'passive' techniques for inertia estimation get less and less accurate and eventually redundant over time. Thanks Pierluigi Mancarella at University of Melbourne and our Reactive Technologies Limited team for the work on this paper .

The global installed capacity of utility-scale battery energy storage systems (BESS) has dramatically increased over the last five years. While recent fires afflicting some of these BESS have garnered significant media attention, the overall rate of incidents has sharply decreased, as lessons learned from early failure incidents have been incorporated into new designs and best practices. #renewables #power #energy #wind #offshore #onshore #solar #hydropower #floating #nuclear #geothermal #efficiency #transition #susteinability #circular #economy #esg #clean #decarbonization #electrification #climate #hydrogen #mobility #greensteel #ammonia #transportation #storage #fuelcell #smartgrid #der #powersystem #generation #transmission #distribution #electricity #machines #drives #sensors #iot #education #engineering #innovation #entrepreneurship #creativity #technology #digitalization #cybersecurtity #metering

EPRI just released a wonderful public-access whitepaper that's mandatory reading for anyone in the BESS industry. Finally, we have a reputable quantitative assessment of grid-scale lithium ion battery failures that validates my perceptions of battery loss trends! Key take aways: 📉 Battery incidents are sharply declining when compared to exponential growth in deployment. The paper shows a headline drop in failure rate of 97% over 6 years! Intuitively, this seems correct, as I track a similar (or slightly declining) number of battery incidents each year, even while deployment is growing by 100% *each year*! 🔥 Each of the main project stages (design, manufacturing, integration/assembly/construction, operation) contribute to battery failures. Diligence is required on all. But integration/assembly/construction is the largest at 36% of identified root causes. The finding that 29% of root causes are attributable to operations also aligns with the finding that ~70% of battery failure incidents occur within 2 years of commissioning. 🤖 The vast majority of battery failures are not actually attributable to cell defects - 89% of failures involved Controls or the Balance of Plant. Battery OEMs are successfully driving down defect rates, and as volumes grow exponentially, the issues with defect rates of 5 years ago are disappearing in a sea of newly produced GWh. But I feel the industry is asleep to other causes of BESS failures, slow to realize that a myopic focus on cell defects is leaving them blind to other root causes. The story in this paper needs to be understood by everyone working with batteries, but especially the insurance industry that is my niche. Insurance costs are often cited as a top-3 opex cost for a battery project, and can even affect project viability! So, I leave with a few calls to action: - Underwriters: get in on the BESS game! Writing policies in a business that is driving down failure rates by 97% over 6 years as it matures should be a profitable place to be! Learn the details and get involved, it's key to making the sustainable energy transition happen. - Owners: keep on top of project risks, and find broker and underwriter partners that also understand them well. Professionals who work in the industry day-to-day will already have intuitive knowledge of the contents of this report, whereas those who rely on media stories or experience from 5 years ago to inform their opinions will be wildly off base. - Loss Control Engineers: We need to raise awareness of battery failures originating from Controls and Balance of Plant (BOP) systems. UL9540A is great data when looking at cell defect hazards, but most insurer engineers and OEMs haven't been looking for data that helps validate against BOP fire scenarios. A few forward looking ones have, and those of us in that category need to raise awareness in the broader industry. Watching the industry grow and mature at such incredible rates is inspiring. Keep building and deploying!🔋
