19 characterizing pv modules using microinverter data finalSandia National Laboratories: Energy & Climate: Renewables
This document discusses using microinverter data from Enphase systems to characterize photovoltaic modules and identify underperformance. Microinverter data provides detailed performance data at the individual module level. The approach infers site orientation metadata like tilt and azimuth by correlating current output with clear sky irradiance models. It also infers module metadata like voltage and current references by analyzing output trends. Together this allows visualization of module performance over time and identification of issues. The analysis does not require external sensors or site visits, using only the microinverter data, with the goal of automatically monitoring many systems.09 mikoski pv-mismatch_pvpmc-8_20170509_r5

This document presents a two-part study on temperature coefficients and thermal uniformity of PV modules and plants:
Part 1 examines the thermal uniformity of cells within modules and modules within PV plants through temperature mapping. It finds frame insulation reduces intra-module temperature differences the most. Backsheets with aluminum covers experience higher operating temperatures.
Part 2 determines climate-specific thermal model coefficients for PVsyst in Phoenix, Arizona based on a year of module performance data. The coefficients vary by technology and mounting, with polymer modules having higher coefficients than glass modules. For c-Si in Phoenix, the recommended coefficients are Uc=25.46 W/m2K and Uv=4.31 W/m3K

This document presents a two-part study on temperature coefficients and thermal uniformity of PV modules and plants:
Part 1 examines the thermal uniformity of cells within modules and modules within PV plants through temperature mapping. It finds frame insulation reduces intra-module temperature differences the most. Backsheets with aluminum covers experience higher operating temperatures.
Part 2 determines climate-specific thermal model coefficients for PVsyst in Phoenix, Arizona based on a year of module performance data. The coefficients vary by technology and mounting, with polymer modules having higher coefficients than glass modules. For c-Si in Phoenix, the recommended coefficients are Uc=25.46 W/m2K and Uv=4.31 W/m3K

Power consumption has become a major concern for almost every digital system: from the smallest embedded devices to the biggest data centers, energy and power budgets are always constraining the performance of the system. Moreover, the actual power consumption of these systems is strongly affected by their current “working regime” (e.g., from idle to heavy-load conditions, with all the shades in between), which depends on the guest applications they host, as well as on the external interactions these are subject to. It is then difficult to make accurate predictions on the power consumed by the whole system over time, when it is subject to constantly changing operating conditions: a self-aware and goal-oriented approach to resource allocation may then improve the instantaneous performance of the system, but still the definition of energy saving policies remains not trivial as far as the system is not really able to learn from experience in real world scenarios.
In this context, this thesis proposes a holistic power modeling framework that a wide range of energy and power constrained systems can use to profile their energy and power consumption. Starting from the preliminary experience developed on power consumption models for mobile devices during my M.Sc. thesis, I designed a general methodology that can be tailored on the actual system's features, extracting a specific power model able to describe and predict the future behavior of the observed entity. This methodology is meant to be provided in an “as-a-service” fashion: at first, the target system is instrumented to collect power metrics and workload statistics in its real usage context; then, the collected measurements are sent to a remote server, where data is processed using well known techniques (e.g., Principal Components Analysis, Markov Decision Chains, ARX models, etc.); finally, an accurate power model is built as a function of the metrics monitored on the instrumented system. The generalized approach has been validated in the context of power consumption models for multi-tenant virtualized infrastructures, outperforming results from the state of the art. Finally, the experience developed on power consumption models for server infrastructures led me to the design of a power-aware and QoS-aware orchestrator for multi-tenant systems. On the one hand, I propose a performance-aware power capping orchestrator in a virtualized environment, that aims at maximizing performance under a power cap. On the other hand, I bring the same concepts into a different approach to multi-tenancy, i.e., containerization, thus moving the first steps towards power-awareness for Docker containers orchestration, laying the basis for further research work.

Aw26312325
This document summarizes a research paper that presents a methodology for cycle-accurate simulation of energy dissipation in embedded systems. The methodology tightly couples component models to enable accurate estimates of performance and energy consumption within 5% of hardware measurements. The simulator can be used to explore hardware design alternatives and estimate the impact of software changes. It also includes a profiler to relate energy consumption to source code, allowing quick identification and evaluation of energy-efficient software optimizations. The tools were tested on an industrial application called the SmartBadge, reducing energy consumption by 77% for an MP3 audio decoder example.
The New Role of Data in the Changing Energy & Utilities Landscape
Watch full webinar here: https://bit.ly/3PrxEx2
Energy companies - both producers and utilities - are facing a challenging and changing business and regulatory environment over the next decade or so. As governments around the world pledge to be 'net zero' by 2050, new regulations are putting pressure on energy companies to accelerate the move to renewable energy sources whilst at the same time gearing up for more widespread electrification as consumers move away from carbon fuels.
The growth of renewable energy sources has also changed the way that utilities manage demand response. The old way of bringing generating units (typically coal or gas-fueled generators) online for peak demand hours no longer works. The distributed utility infrastructure that is used today requires a lot more flexibility and planning to meet - and to shape - consumer demand.
At the heart of the energy company challenges is data. Data to better manage and optimize the generating resources. Data to better inform the consumers about their energy consumption. And data to deliver better services and new product offerings to those consumers.
In this webinar, we will look at how energy companies and utilities can liberate and democratize their data to better utilize the strategic data assets that they already own. We will look at how the Denodo Platform, powered by Data Virtualization, has helped energy companies around the world access real-time data to drive their operations and allow them to respond to the ever-changing business environment.

11 Testing Shear Strength and Deformation along Discontinuities in SaltSandia National Laboratories: Energy & Climate: Renewables
Sandia National Laboratories is conducting laboratory and potential underground tests to better understand shear stresses and strains along discontinuities in salt formations. Upcoming laboratory tests in 2017 will apply controlled shear stresses to salt samples containing clay seams and measure the effects on shear and fracture strength. The results will be used to improve models of shear behavior along interfaces. Potential future underground tests in a salt alcove in 2018 would apply stresses to a salt pillar containing a clay seam using pressurized flatjacks to directly observe shear deformation responses in situ. The aim is to reduce modeling uncertainties regarding permeability and deformation of salt near discontinuities.10 Current status of research in the Joint Project WEIMOS

23 Sandia’s Salt Design Concept for High Level Waste and Defense Spent Nuclea...Sandia National Laboratories: Energy & Climate: Renewables
Sandia National Laboratories researchers presented a preliminary salt design concept for disposing of high-level radioactive waste and spent nuclear fuel in salt geologic settings. They proposed direct disposal of glassified high-level waste in stainless steel canisters and using robust steel overpacks for spent nuclear fuel. Waste packages would be emplaced transversely in just-in-time constructed drifts and immediately backfilled with crushed salt to limit radiation exposure and provide stability. Thermal analysis indicated waste package spacing of around 8 meters for spent fuel and 3 to 7.7 meters for high-level waste would be sufficient to limit temperatures. The design aims to simplify handling and take advantage of salt's ability to self-heal around the waste packages.22 WIPP Future Advancements and Operational Safety

16 Reconsolidation of granular salt (DAEF report)Sandia National Laboratories: Energy & Climate: Renewables
The document summarizes an assessment of existing experimental data and constitutive models for predicting the behavior of crushed salt backfill during reconsolidation in a salt repository. It finds that while several thermo-mechanical models have been developed, the experimental database is incomplete, particularly for the low porosity range under relevant conditions. It recommends future work to complete the database through improved experiments and to calibrate and benchmark models against experimental results to enable reliable predictions of long-term behavior and hydraulic properties.15 Outcome of the Repoperm Project
The Repoperm project studied the mechanical and hydraulic behavior of compacting crushed salt backfill at low porosities. It found that:
1) Measurement of properties like permeability and constitutive relationships for two-phase flow are possible down to gas permeabilities of 10-15 m2.
2) Presently used models have limits and material parameters depend on the specific test, so predictive capability needs improving.
3) Further research is needed to fully characterize hydro-mechanical behavior, understand permeability under unsaturated conditions, and reconcile results from different test types.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
