MicroGrid and Energy Storage System COMPLETE DETAILS NEW PPT Abin Baby
A microgrid is a localized grouping of electricity generation, energy storage, and loads that normally operates connected to a traditional centralized grid (macrogrid). This single point of common coupling with the macrogrid can be disconnected. The microgrid can then function autonomously. Generation and loads in a microgrid are usually interconnected at low voltage. From the point of view of the grid operator, a connected microgrid can be controlled as if it were one entity.
Microgrid generation resources can include fuel cells, wind, solar, or other energy sources. The multiple dispersed generation sources and ability to isolate the microgrid from a larger network would provide highly reliable electric power. Produced heat from generation sources such as micro turbines could be used for local process heating or space heating, allowing flexible trade off between the needs for heat and electric power.
Wide area monitoring systems (WAMS) are essentially based on the new data acquisition technology of phasor measurement and allow monitoring transmission system conditions over large areas in view of detecting and further counteracting grid instabilities.
Distributed generation of electric energy has become part of the current electric power system. In this context, a recent research study is arising on a new scenario in which small energy sources make up a new supply system : The Microgrid. The most recent projects show the technical difficulty of controlling the operation of Microgrids, because they are complex systems in which several subsystems interact: energy sources, power electronics converters, energy systems, linear and non-linear loads and of course, the utility grid.In next years, the electric grid will evolve from the current very centralized model toward a more distributed one.

Challenges and Benefits of Integrating the Renewable Energy Technologies into...Power System Operation
In the recent decent, renewable energy has been becoming one of the independent energy sources in human life, and it will be a major resources for the future generation of power. Today, some people tend to use renewable energy in their home or land such as solar or wind energy. Most of those have two inputs of the power source; the utility power supply and renewable energy power supply, so the integration of renewable technologies variable generation sources within Ac grid has been made, but this connection is not easily reachable. This paper will be reviewed the challenges and benefits of integrating renewable energy into power system grid. A review of the integration process will be introduced. Also, the paper will discuss some difficulties that face the integration such as power quality requirements that must be achieved to get this connection successfully. Forecasting of renewable energy such availability of power at any time, the amount of variation in power output, the speed of variation, and the location of RE source are other challenges that may obstruct the successful incorporation of renewable energy and the grid. In addition, the paper will briefly show a device that can be used in homes to achieve this connection. Finally, advantages of the integration for both the power utility and the green energy owner will be present, and how this integration can affect our environment. Solar energy and wind energy will be used in this paper as examples of renewable energy. Keywords: grid, green energy, integration, global warming, renewable energy RE
This chapter deals with the power system operation of different power system parts which includes the generation, transmission and distribution systems. This slide is specifically prepared for ASTU 5th year power and control engineering students.

Conclusion
Successful implementation of DR program is possible if the users participates into it willingly without compromising with their comfortable life style
DR program does not ensure same amount of benefit for all the participating players i.e, some may be incentivized whwre as some can receive penality.
The employment of DR relies on the reliable,robust and secure communication system.
Choice of efficient energy price structure is the main key factor to attract the users towards DR programs.
An embedded system's input devices have quite limited capabilities. Since there won't be an input device or mouse, as there are in computer systems, interacting with the embedded system won't be simple. Input devices for user interaction are absent from numerous embedded systems used in process control. They receive input from transmitters or detectors that will generate electrical signals which are fed to other mechanisms.
The capabilities of the embedded systems' external devices are also extremely constrained. A few LEDs may be present in some embedded systems to show the modules' overall health or to signal alarms visually. Some important aspects may also be displayed on LCDs.Embedded systems are widely used in a variety of industries. Due to the wide range of applications for these systems, the embedded system market is one of the most dynamic.
Consumer devices, process automation, medical technology, wireless and data communication, the military, automotive, and aerospace, as well as household appliances are all examples of this.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Issues faced by developer for net metering
1. ISSUES FACED BY DEVELOPER
FOR NET METERING
BY:-
Ankur Tyagi
MBA 14TH BATCH
2. CONTENT
• Net Metering
• Issues & challenges for Net Metering
• Net Metering policies of Maharashtra, Andhra
Pradesh, Karnataka, Madhya Pradesh
• Way forward
4. Gross Metering
• In Gross metering arrangement ( popular in Germany)
entire energy generated by the system is fed directly into
the grid and system owner benefited by sale of power to
the utility at a pre-defined feed-in-tariff (FiT)
• In Gross feed in setup utilities install two meters on the
consumer premises to separately measure the total
electricity exported and imported. Bills are generated
based on difference between the two, given the retail
consumption tariff and the feed in tariff.
• Gujarat, Andhra Pradesh, Goa & Uttar Pradesh allow gross
metering for rooftop solar plant
• Gross metering is more successful where solar tariff is
higher than conventional tariff.
5.
6. Net Metering
• Net Metering (popular in US & Japan) primarily allows self
consumption of generated power while enabling the sale or
banking of additional generation with discom.
• In net feed in model a single bidirectional meter is deployed,
electricity generated by solar panels is consumed within
consumer premises and any excess is exported to the grid and
any deficit is drawn from the grid. The bidirectional meter
measures the net exports and imports to generate electricity
bills.
• Andhra Pradesh, Uttar Pradesh , Maharashtra, Delhi etc. allow
net metering for rooftop solar plant
• Net metering is more successful where solar tariff is equal or
lower than conventional tariff otherwise require financial
incentives/ subsidy.
7.
8.
9. Advantages of Net Metering
• Reduce consumer bills
• Eliminates battery requirement- reduce storage loss & cost
• Low gestation time
• Saving in Transmission & Distribution Losses
• No requirement of land
• Improvement of tail end grid voltage
• Reduction in system congestion
• Local employment generation
• Increases grid reliability by lowering transformer loading and back up
supply
• Improved power quality especially voltage profile with associated reactive
power support by inverters
• Deferring grid investment & costlier peak power purchase cost
• Help in Climate Change mitigation by promoting clean energy
development.
10. ISSUES FACED BY DISCOMS
• Revenue loss to utilities :-
― Reduction in sales volume
― Difficulty in fixed cost recovery due to shifting of consumer to low consumption slab
― Difficulty in recovery of cross subsidy charges due to migration of high paying consumers to
solar rooftop
• Problem with Grid management as solar generation is variable peak in afternoon while peak
load is in evening. Grid treated as backup power source.
• Technical issues like power quality, phase imbalance etc.
• Reactive Power overcompensation due to oversize capacitor banks
• Safety issue due to Islanding during O & M of grid
• Non Coverage of RTPV in TOD system
• Increase in administrative burden (application, registration, technical feasibility study,
inspection, connectivity, metering & billing etc.)
• Increase in financial burden as DISCOM require to pay consumer and invest in grid
upgradation
• Higher wear and tear of Distribution system equipment.
• Higher transaction effort and cost in terms of metering, inspection and certifications.
11. • Metering & Energy Accounting
• Interconnection Arrangement
• Commercial Settlement Process
• Applicability of Regulatory Instruments
ISSUES FACED BY DEVELOPERS WRT
DISCOMs
12. Metering & Energy Accounting
• Non availability of standard, model for Net metering schemes
• Absence of standard Net meter specifications, specifically with
respect to 1 Ph. Connections. Code of practices for use of different
class of import, export meters and generation meter
• Lack of clarity on role of different entities in bilateral/ tripartite
arrangements in project developed by owner/ third party
• Unawareness and lack of clarity in DISCOMS for policy & regulations
• Improper definition of Net metered consumer related to coverage
of self-owned and/or third party developed projects
• Non availability of provisions towards TOD settlements as to how to
align energy settlement under Net metering with the existing
framework
13. Interconnection Arrangement
• Inadequate (Aged) LT level & HT level distribution system (most of DS are
very old and designed for unidirectional flow)
• No proper Grid Management system at Discom level
• Inadequate availability of Net Meters in market
• Power quality already an issue with Discoms
• Low Reliability- Load shedding & Power Outage is very huge ( Loss of PV
Generation as inverter works on reference voltage of Grid)
• Cap on RTPV installation wrt to connected load and total consumption
• Cap on RTPV cumulative installation capacity wrt Distribution Transformer
Capacity ( not an issue at low penetration)
• High capacity rooftop to be connected at HT level that incurs extra cost on
transformers, switchgears and system losses with increase in project
completion time
• Safety Concern due to unintentional islanding or reverse flow of power
• Issue with testing facilities and quality assurance
14. Safety Concern
For the safe system operations of an interconnected distribution
generation following is important:
• Self islanding in the event of Grid faults i.e. protection from
distribution system faults
• Auto cut-off from Grid in the event of internal PV system
breakdown ; Cease to feed power to Grid
• Prevention of feeding power to Grid in the event of Grid
fault/System Break down (Anti- Islanding )
• Protection to People (Public & Utility workers) and Property
• Protection from abnormal Voltage & Frequency levels
• Protection while synchronization with Grid
• Protection against injection of Harmonics, DC supply & Flicker etc.
to the Grid
15. Commercial Settlement Process
Commercial settlement in net metering depends upon:
• Definition of eligible consumer
• Generation capacity limits
• Interconnection voltage
• Energy Accounting
• Net metering settlement period
• Restrictions on level of overall or local Grid penetration
• Renewable Purchase Obligation (RPO)
• Application of other charges & incentives (fixed charge,
connectivity charge, TOD, ABT, GBI) etc.
16. • Cumbersome & Long Approval Process
• Inadequate commercial settlement process
(Discoms Billing Process)
• Weak Financial conditions of Discoms- Not
able to pay pre decided Net Metered Tariff
• Lack of trained manpower for rooftop system
in Discoms
Commercial Settlement Process
17. Applicability of Regulatory
Instruments
• Non availability of clearly defined technical standards and guidelines for Grid
connectivity, metering, safety and security etc. are major barriers in
implementation of such projects
• Current Regulatory framework also lack in addressing the charges related to
wheeling, open access, Cross subsidy etc.
• Indian standards for installation & testing etc. is must in line with international
equipment standards issued by International Electro technical Commission (IEC)
• Unrealistic Net Metering Tariff
• No carry forward of energy allowed to next financial year
• Cap on credited energy adjustment during peak time/seasons
• Cross Subsidy in Tariff structure- Residential, Agriculture & Domestic consumer are
less interested in Rooftop
• Focuses more on self-consumption and energy banking instead of selling power to
utilities.
• REC Mechanism not eligible
• RPOs are not mandatory
18. Other Issues
• High upfront cost involved in putting up solar
panels on rooftops
• Lack of awareness among consumers
• Reluctance by Discoms due to loss of revenue
by decrease in sales, shifting of consumer in
lower consumption slab, reduction in fixed
cost recovery.
19. Technical Issues
• Safety of Utility work personnel due to unintentional Islanding ( Anti
Islanding Function)
• Safety of PV system from grid faults
• Quality of Power being injected in the grid (Harmonics, Flicker, DC
injection, Voltage & Frequency range, Reactive Power Support ,
LHVRT & LHFRT, Power frequency droop characteristics etc.)
• Phase Imbalance
• Reverse Power Flows & associated loss of voltage regulation
• Issues related to protective equipment , earthing and metering
( Above all are not an issue with modern solar inverters with
appropriate protection)

NET METERING POLICY
24. Way Forward
• Success of Net Metering Depends on support by Discoms and incremental tariff
available to consumers
• Regulations can be tweaked and revised but the key challenge is in
implementation
• There is a need for clear implementation guidelines for utility staff to enable
interpretation of the rules
• There is need for establishment of single window clearance mechanism and
uniform well designed application forms that will help to reduce timeline for
approval and make process simpler for consumer
• Thus discoms need to be brought on board to support net metering as most of
discom view net metering framework as being unfavorable to their business.
• The government must create an incentive structure such that the benefit from
rooftop solar are shared with the utilities.
• The government must create an incentive structure such that residential, domestic
and agriculture consumer move more toward rooftop PV system ( multi benefit
reduce losses and cross subsidy)
25. Way Forward
• Globally, major PV installations have been on rooftops in countries like Germany, Japan and USA.
Given the global trend, high solar irradiation, growing energy demand & power deficit issue and
abundance of rooftops for SPV systems installation, SPV rooftop system seems a logical alternative
choice to meet India’s energy requirements.
• Solar power has already achieved parity with commercial power tariffs for industrial and
commercial segment in many states in India. However, SPV rooftop installations are at very nascent
stage in India with total installed capacity of 1GW (approx on sep. 2016) as against targeted SPV
rooftop installations of 40 GW by 2022 and hence, capital subsidy alone may not be the solution to
achieve targeted installations but comprehensive solar solutions is the need of the hour.
• Implementation of SPV rooftop systems can be accelerated if solar solutions are easily available and
accessible as a complete package; easy financial assistance is available and there is increasing
awareness amongst consumers about its economic/environmental benefits. Promoting SPV rooftop
for self-consumption could be the most important step towards popularising SPV rooftop. Large
participation across the consumer segment may be achieved through creating awareness about
benefits supported by synchronisation between stake holders i e Government nodal agencies,
consumers and system integrators.
• Furthermore, government policies should also put emphasis on encouraging power generation
through decentralised SPV rooftop systems at the point of consumption rather than only providing
capital subsidy. One of the ways could be through providing generation based incentives for end-
users including the house hold segment which can drive growth of SPV rooftop systems without
putting any additional burden on distribution and transmission infrastructure while at the same
time achieving targets for renewable energy installations.
