The document discusses a gearless magnetic wind/solar powered turbine storage system called GMAG-WINDSOPTSS. It aims to design a prototype turbine that uses wind and solar power to charge batteries and power a home electrical grid as an emergency backup system. The turbine would use a spiral axis design based on an existing model, with magnetic levitation to eliminate bearings. It would include solar panels, batteries, inverters, converters and controls. Performance is analyzed for Huntsville, AL wind speeds which average around 15 mph and are sufficient to operate a small turbine. The project is broken into phases with milestones to complete design, testing, and implementation.

1) Solar energy adoption is growing in the US, with over 13,000 MW of solar capacity installed as of 2014. The utility scale solar market is leading the way.
2) The US military is also increasing its use of solar power, with a goal of obtaining 25% of its energy from renewable sources by 2025. Several large solar installations have been completed at military bases.
3) While higher efficiency solar cells can be developed in research settings, the cost-effectiveness of a solar installation depends more on the total cost per watt including installation and maintenance over the long-term. Balance of system costs are a major factor.
5.5 off main-grid technologies for power generation in rural contexts
This document provides an overview of off-grid power generation technologies for rural contexts. It begins with a 4-step process for designing off-grid energy systems that matches local needs with available resources in an optimized and cost-effective manner. The document then discusses assessing local energy needs and available solar, wind, and hydro resources. It provides technology summaries of solar photovoltaics, small wind turbines, and small hydropower systems. Hybrid systems that combine these technologies with batteries or diesel generators are also discussed. The document concludes with considerations for evaluating the impact of off-grid technologies on local development.
Getting the Most out of your Electrical Room
This document discusses trends in electrical rooms and expectations for equipment. It aims to clarify terms and standards to increase awareness and address common questions about electrical rooms. Integrated switchboards and integrated motor control centers are presented as space-saving alternatives to conventional stick-built designs. Integrated solutions can reduce the electrical room footprint by consolidating components and eliminating unnecessary space. Device-level networking is also discussed as a way to further minimize space by replacing field wiring with communication networks.
Consumer Basics for Renewable Energy
This document provides an overview of consumer basics for renewable energy projects. It defines key energy terminology, discusses technology basics like power ratings and capacity factors, and outlines the process for sizing and connecting a micro-generator system. Requirements vary by location but may include permits, approvals, and interconnection with the local grid. Economics depend on system costs, predicted production, and compensation rates. Resources are available to help consumers research contractors and understand their rights.
Energy storage (why & how)
Energy storage can help integrate renewable energy sources by storing excess production for times when supply is low. However, current storage technologies are too expensive to deploy widely. Alternatives include improving demand management and allowing generators to better adjust output to changing demand. Further development is needed to reduce storage costs before it can be broadly implemented on power grids.

This document summarizes EDF Energy's experience with a loss of off-site power event at their Hunterston B nuclear power station in Scotland. It describes how all grid power was lost on two separate occasions during a major storm in 1998, forcing the reactors to rely on emergency diesel generators and natural circulation cooling. Operators faced many challenges in maintaining safe shutdown. As a result, EDF improved operator training for such events, enhanced on-site emergency capabilities, and implemented recommendations from a worldwide industry report on the risks of lost off-site power.Recommandé

introduction on high voltage engineering
This document provides an introduction to high voltage engineering and the structure of power systems. It discusses how transmitting electricity at high voltages reduces power losses and infrastructure costs during transmission over long distances. The key components of a power system are generating stations, transmission lines, and distribution systems which are organized into regional grids connected by transmission lines. Power stations can be sited near coal mines or load centers depending on various technical and economic factors.
Planning a successful microgrid
New York’s Reforming the Energy Vision (REV) initiative seeks to fundamentally transform the way electricity is distributed, generated and used across the State. Utilities are being challenged to adapt their business models and distribution infrastructure to meet these new goals. REV also presents an opportunity for utilities to provide their customers with a broader range of services that lead to a more diverse, innovative and resilient energy infrastructure.
A key focus of REV is the transition to local distributed energy platforms including microgrids, which can be operated in conjunction with the grid or independently in emergencies. TRC recentlypresented an educational webinar to help New York’s utilities and other decision makers take action to plan and implement successful microgrids. This presentation covers:
• Basic concepts for developing a microgrid
• Differences from operating within the conventional grid
• Preliminary engineering steps required
• Options for generation sources

ECBC
The ECBC Building Code provides minimum energy efficiency requirements for commercial buildings in India to reduce their energy consumption and environmental impact. It applies to buildings with a connected load over 500kW or air conditioned area over 1000 sqm. The code covers requirements for building envelopes, mechanical systems, lighting, and electrical systems. Compliance with the ECBC is estimated to reduce energy use in commercial buildings by 30-40% compared to conventional buildings. Widespread adoption of the code could help India save 1.7 billion kWh of electricity annually according to BEE estimates. The code is currently voluntary but aims to become mandatory nationwide to significantly increase energy savings.
Energy Storage: New Capabilities for the Electric Grid – The Tehachapi Energy...
The Tehachapi Energy Storage Project (TSP) is a 32 megawatt-hour battery energy storage system located in California that was jointly funded by Southern California Edison and the US Department of Energy. The project tested the battery storage system for 13 grid support applications. Initial testing showed the system could discharge 32 megawatt-hours over 4 hours as required and had an average round-trip efficiency of 90.6% during continuous cycling. However, the project faced challenges including replacing power conversion system transformers after one failed due to an unmet design requirement.

This document discusses optimal placement of energy storage devices (ESDs) in microgrids to improve transient stability. It first develops a new energy function model for microgrids since existing models for conventional power systems do not apply. It then proposes a novel approach to determine the optimal placement of ESDs based on the microgrid energy function to maximize stability. Simulation results demonstrate the method can effectively find placements of ESDs that improve system stability.

This document summarizes a proposal for modular spacecraft with integrated structural electrodynamic propulsion. It describes using short, rigid booms carrying large currents to generate thrust via Lorentz forces with little or no propellant. Six booms could provide full spacecraft control. Modular components could self-assemble large structures. Challenges include complex dynamics, constrained thrust vectors, and relying on ambient plasma. Energy storage, electron emitters, ion sources, and plasma collection are also discussed.
Dynamic modelling of a parabolic trough solar power plant
Models for dynamic simulation of a parabolic trough concentrating solar power (CSP) plant were developed in Modelica for the simulation software tool Dymola. The parabolic trough power plant has a two-tank indirect thermal storage with solar salt for the ability to dispatch electric power during hours when little or no solar irradiation is present. The complete system consists of models for incoming solar irradiation, a parabolic trough collector field, thermal storage and a simplified Rankine cycle.
In this work, a parabolic trough power plant named Andasol located in Aldeire y La Calahorra, Spain is chosen as a reference system. The system model is later compared against performance data from this reference system in order to verify model implementation. Test cases with variation in solar insolation reflecting different seasons is set up and simulated.
The tests show that the system model works as expected but lack some of the dynamics present in a real thermal power plant. This is due to the use of a simplified Rankine cycle. The collector and solar models are also verified against literature regarding performance and show good agreement.

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.

Widespread adoption of the code could help India save 1.7 billion kWh of electricity annually according to BEE estimates. The code is currently voluntary but aims to become mandatory nationwide to significantly increase energy savings.
Energy Storage: New Capabilities for the Electric Grid – The Tehachapi Energy...
The Tehachapi Energy Storage Project (TSP) is a 32 megawatt-hour battery energy storage system located in California that was jointly funded by Southern California Edison and the US Department of Energy. The project tested the battery storage system for 13 grid support applications. Initial testing showed the system could discharge 32 megawatt-hours over 4 hours as required and had an average round-trip efficiency of 90.6% during continuous cycling. However, the project faced challenges including replacing power conversion system transformers after one failed due to an unmet design requirement.

This document discusses optimal placement of energy storage devices (ESDs) in microgrids to improve transient stability. It first develops a new energy function model for microgrids since existing models for conventional power systems do not apply. It then proposes a novel approach to determine the optimal placement of ESDs based on the microgrid energy function to maximize stability. Simulation results demonstrate the method can effectively find placements of ESDs that improve system stability.

This document summarizes a proposal for modular spacecraft with integrated structural electrodynamic propulsion. It describes using short, rigid booms carrying large currents to generate thrust via Lorentz forces with little or no propellant. Six booms could provide full spacecraft control. Modular components could self-assemble large structures. Challenges include complex dynamics, constrained thrust vectors, and relying on ambient plasma. Energy storage, electron emitters, ion sources, and plasma collection are also discussed.
Dynamic modelling of a parabolic trough solar power plant
Models for dynamic simulation of a parabolic trough concentrating solar power (CSP) plant were developed in Modelica for the simulation software tool Dymola. The parabolic trough power plant has a two-tank indirect thermal storage with solar salt for the ability to dispatch electric power during hours when little or no solar irradiation is present. The complete system consists of models for incoming solar irradiation, a parabolic trough collector field, thermal storage and a simplified Rankine cycle.
In this work, a parabolic trough power plant named Andasol located in Aldeire y La Calahorra, Spain is chosen as a reference system. The system model is later compared against performance data from this reference system in order to verify model implementation. Test cases with variation in solar insolation reflecting different seasons is set up and simulated.
The tests show that the system model works as expected but lack some of the dynamics present in a real thermal power plant. This is due to the use of a simplified Rankine cycle. The collector and solar models are also verified against literature regarding performance and show good agreement.

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.
