Isolated island power systems are experiencing unprecedented demands for the connection of solar PV. This is currently seen as a threat to traditional utility models. As costs of renewable energy are decreasing, there is increasing complexity in the integration and the economics surrounding this. The realisation of existing investments in networks and generators is often shaping the discussions and way forward. The presentation will discuss the impact of disruptive technologies on islanded systems.

THE U.S. ENVIRONMENTAL PROTECTION AGENCY CLEAN POWER PLAN: HOW WILL IT AFFECT THE ELECTRIC UTILITY INDUSTRY NOW AND IN THE FUTURE?
On June 2, 2014, the U.S. EPA, proposed a plan with the stated purpose of reducing carbon emissions from electric generating units, under Section 111(d) of the Clean Air Act. The CPP sets a CO2 emission target for each state, and utilizes four “building blocks” in devising those rates. The CPP suggests power to be dispatched based upon environmental considerations. Today, regional electric markets dispatch power based upon economic considerations and not environmental considerations. More than four million entities submitted comments on the proposed CPP and on August 3, 2015, the U.S. EPA issued their final plan. What is the overall affect on states, utilities, and ratepayers? What is the timeline for implementation of the CPP? What does the plan mean for the future electric generation mix? How will reliability and prices be impacted? What kinds of technology and regulatory policy changes will be needed?

INTERRUPTION IN THE UTILITY INDUSTRY?
Track 1 Session 1
Electricity markets are experiencing fundamental changes because of solar, wind, electric vehicles, energy efficiency programs, storage and other forms of distributed generation that may be intermittent or require changes/upgrades to the electric grid. There is also an increase in the availability of smart meters and other devices that can help customers control their electric demand and usage. As a result, demand is less predictable and more volatile. This change also creates challenges for transmission and distribution for all load serving entities, even with new real-time data availability and grid visibility. What technological, regulatory, and/or policy changes are needed in the short term and longer term to keep pace? What will these changes mean for reliability? How will the traditional utility model change in the coming years?

Webinar recording at https://youtu.be/2A-aVb6OHTE
The coordination between planners and operators of coupled energy systems will allow the further integration of renewable energy sources in the electricity network by storing energy in fuel form over long periods of time using power-to-gas, the recovery and more efficient use of heat, and the decarbonization of industrial processes and transportation modes that can’t be electrified. Energy networks, such as electricity grids and natural gas pipeline networks, have traditionally been planned and operated independently. In order to enhance the integration and coordination of different energy networks, they must be planned and operated in coupled ways. Different energy networks have historically been and are still modelled by different tools. In this presentation we will discuss the need model coupled energy systems in a single framework and we will introduce encoord’s Scenario Analysis Interface for Energy Systems (SAInt), a software application to model, plan, and operate coupled energy networks.

Clean energy transition – challenges and opportunitiesFrank Guo
• Decarbonization creates significant changes in
the characterization of the grid from resource mix
to demand composition
• Such changes bring many challenges to both
system and market operations in terms of
reliability, efficiency and complexity.
• To support such transition to the future grid, both
operational enhancements and alignment of
market structure are needed.
Sustainable energy for whom? Governing pro-poor pathways to low carbon energy...STEPS Centre
David Ockwell and Robert Byrne (University of Sussex/ STEPS Centre) gave this presentation at King's College London on 25 February 2014 as part of the Environment, Politics and Development Research Group seminar series.
Despite the potential development benefits of low carbon energy technologies, existing international policy has failed to deliver against the needs of low income countries or poor and marginalised people therein. This seminar presents (and seeks feedback on) preliminary findings from a CDKN-funded project on off-grid solar electrical services in Kenya (see http://steps-centre.org/project/low_carbon_development/ ). Utilising the STEPS Centre’s Pathways Approach, it is argued that the failure of existing policy stems from its tendency to frame low carbon development as a problem of financing low carbon hardware transfer to developing countries. Alternative conceptual framings, building on insights from innovation studies and socio-technical transitions, applied to in-depth historical analysis of the successful adoption of off-grid solar in Kenya, suggest neither hardware financing policies nor the free market are likely to result in widespread uptake of low carbon energy technologies amongst poor countries and poor people therein. Instead, interventions should seek to act as “innovation system builders” with an explicit focus on building inclusive innovation systems via a range of specific capacity building approaches.
Dr David Ockwell is a Senior Lecturer in the Dept of Geography at the University of Sussex and co-convenes the STEPS Centre’s energy and climate domain. He’s also affiliated to the Sussex Energy Group and the Tyndall Centre. David’s research focuses on low carbon development with particular recent emphasis on the implications of international policy in terms of poverty and social justice.
Dr Rob Byrne is a Research Fellow in SPRU (Science and Technology Policy Research) at the University of Sussex. He co-convenes the STEPS Centre’s energy and climate domain with David and is also affiliated to the Sussex Energy Group and the Tyndall Centre. Rob’s research focuses on low carbon development with a particular empirical focus on off-grid solar electrical services in East Africa where he has worked both as a practitioner installing solar home systems as well as conducting academic research on this issue

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.

With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
ISI 2024: Application Form (Extended), Exam Date (Out), EligibilitySciAstra
The Indian Statistical Institute (ISI) has extended its application deadline for 2024 admissions to April 2. Known for its excellence in statistics and related fields, ISI offers a range of programs from Bachelor's to Junior Research Fellowships. The admission test is scheduled for May 12, 2024. Eligibility varies by program, generally requiring a background in Mathematics and English for undergraduate courses and specific degrees for postgraduate and research positions. Application fees are ₹1500 for male general category applicants and ₹1000 for females. Applications are open to Indian and OCI candidates.
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

2. What is energy security?
• IEA definition
– energy security as the uninterrupted availability of
energy sources at an affordable price.
• Energy security has many aspects:
– Long-term energy security mainly deals with timely
investments to supply energy in line with economic
developments and environmental needs.
– Short-term energy security focuses on the ability of
the energy system to react promptly to sudden
changes in the supply-demand balance.
3. Many aspects of Energy Security
1. Diversity of supply
2. Level of imports
3. Security of trade flows
4. Geopolitics and economics
5. Nuclear proliferation
6. Diversity of resources
7. Market/price volatility
8. Affordability / economic impact
9. Energy intensity
10.Reliability
11.Feasibility Centre for Strategic and International Studies www.csis.org
4. 1 Diversity of supply
• Over-reliance on:
– any one supplier
– group of suppliers
– A particular region
• security of a given region:
– political instability
– economic risk
• More diversity = better energy security.
• Ease of finding a replacement for a fuel being supplied:
– Fungibility (substitutability)
– Surplus capacity

Impact of oil bill
Net oil imports Non petroleum exports Net oil imports as % of non petroleum exports
6. Level of imports
• Less imports, the better
• Access to globally traded energy commodities
• Links to regional grids, gas networks etc.
7. 3 Security of trade flows
• Major portion of world oil squeezes through
five narrow channels
– Always better to depend on multiple channels
• Cross border energy trade
– Transit countries can make or break supply
8. 4 Geopolitics and economics
• Rise of large economies (India / China) with
growing appetite for energy
– Who will wield power over whom?
• Free and open global trade is a thing of the
past
• Oil producing countries now ‘awake’
– Rise of militancy an indication
9. 5 Nuclear proliferation
• Nuclear energy was seen as a cure
• Proliferation risks and safety issues took away
this opportunity
• No solution to waste problem
10. 6 Diversity of fuels
• Over dependence on one source
– Hydro then, oil now and may be coal next
• Whether renewable or not, the risks are
similar
– Droughts driven power cuts and severe impact of
oil price peak
• Over diversification
– If the fuels are not easily substitutable
– May need large infrastructure investments
12. 7 Market/price volatility
• Higher volatility = uncertainty
– Differs or scuttles long term investments
– Degenerated infrastructure
• Energy ‘futures’
– Renewable energy and energy efficiency are two
such insurance schemes
13. 8 Affordability / economic impact
• Individual citizens
– Cost of energy products in the total cost
– Even if energy supply is secure, affordability and
affordability alone will drive economic growth
• Nations
– Cost of providing energy to realise economic
output
14. 9 Energy intensity
• Lower, the better insulated we are
– Price driven reductions are not counted!

15. 10 Reliability
• The prevalence of an energy supply
– Aging infrastructure, mismanagement and neglect
• Issues with technology and knowledge
– Coal power plant vs. refinary
16. 11 Feasibility
• Enlarging the workspace – the only way to
embrace new things (technology)
– Pushing further is a must
– Pushing too hard may be harmful
• The pace of previous evolutions must be
understood
– Case of biomass energy models
– Case of affordable storage
17. Technology roadmaps
• As a decision aid, roadmaps are useful tools for:
– Strategic and operational decision making and action planning
– Achieving a desired future state of development
– Portraying structural relationships among S&T and applications
– Improving coordination of activities and resources
– Identifying, evaluating and selecting strategic alternatives
– Communicating visions to attract resources
– Stimulating investigations
– Monitoring progress
19. Basic architecture of roadmaps
• An S&T roadmap consists of
nodes and links
• These elements can have
quantitative and qualitative
attributes.
• Construction of a roadmap
requires identification of the
nodes and their attributes,
connecting the nodes with
links, and specifying the link
attributes.
21. Resource Development
• Real economic growth has always been...
– very closely associated with the development of
human capital of the country
– focused attention to develop HR to undertake
complex and difficult tasks
• Countries with vast natural resources but very limited HR, tend
to be quite vulnerable to external factors
– Hence it is very important to clearly define the
difference between resource exploitation and
resource development
22. The difference…
• Resource exploitation is the process of
applying external knowledge, experience and
investment to utilise natural resources
– Mostly in raw material form
• Resource development is the process of
developing own knowledge, expertise and
capability to utilise natural resources
– An industry by itself

24. Do we have a fair chance ?
• RE technologies,
– Remain within the borders of clusters of developed countries
– Or within regions and economic blocs
• Need for significant capacities in RE and necessity to democratise
RE technologies
– Mature economies offer very limited manufacturing capacity
• Debt crises
• Sovereign bond crises
• Aging populations
• Opportunities for emerging economic engines (India & China) to
move in quickly, with vigour and strength
– from a growing economy
– a younger population
– sufficient clout, even to force shut many infant industries in other
countries by resorting to dumping?
• What have we done to embrace sustainable energy technologies ?
25. A case in point
• Manufacturer of hydropower turbines
– Board of Investment registered company is prevented from selling
more than 20% of the output to the local hydropower industry.
– Company can supply nearly 75% of the local demand
– Will not have VAT concessions, available to competing imported
products, tariff incentive abused
• A case for wind turbine manufacturing industry
– Taking initiatives to enter local market
– Significant advantages from logistics
– A reality, dawned sooner than we expected – now a worrisome audit
investigation !
• A case for electric vehicle manufacturing industry
– Long delays, lack of commitment – another worrisome audit
investigation..!
27. A new approach
• Based on old principles
– Integration backward?
– Integration forward?
– A combination of both ??
• A virtuous cycle
– Having three major elements
• Resource Development
• Technology Development
• Investment

45. Why we fail
• We ‘invent’ things and struggle to market it
• They ‘solve’ real problems
– An industry partner, university and a match maker (NEDO)
• Absolute lack of industry leadership (mostly a pack of
followers)
– Risks too high for our feeble, infant and budding industries
• Unwillingness to pay for knowledge
– They will part with 16 million dollar for a 10MW wind
plant, but will attempt to steal a feasibility report without
paying a consultant 5,000 dollars..!
– Distrust of the research community
• Reward / penalty structure of research community
– No incentive to do, safer to avoid
46. Conclusion
• Strategic alliances must be built
– Industry, research and catalysts (local or foreign)
• Status and image of research community must
be elevated
– They must be consulted (not the electrician..!)
• Government must take more risks
– Industry must take some risks
• Few longer term thrusts must be nurtured
