Q.1 What are the
challenges and opportunities associated with integrating energy storage systems
into the electrical grid?
Cost: Energy
storage systems can be expensive to deploy and maintain. The initial capital
costs for large-scale storage installations can be significant, although they
are decreasing as technology advances and economies of scale are achieved.
Technology:
Developing reliable, efficient, and scalable energy storage technologies that
can meet the demands of the grid is a challenge. Different applications may
require different types of storage technologies (e.g., lithium-ion batteries,
pumped hydro storage, flywheels), each with its own set of technical
challenges.
Intermittency
and Variability: Renewable energy sources like solar and wind are intermittent
and variable in nature, which can lead to imbalances between electricity supply
and demand. Energy storage can help mitigate these issues by storing excess
energy when supply exceeds demand and releasing it when demand is high, but
optimizing the operation of storage systems to effectively manage fluctuations
can be complex.
Regulatory and
Policy Barriers: Regulatory frameworks and policies may not always be conducive
to the deployment of energy storage systems. Existing regulations may not
adequately address the unique characteristics and benefits of storage, leading
to barriers such as limited market access, unclear compensation mechanisms, and
regulatory uncertainty.
Grid Integration: Integrating energy storage systems into the existing grid infrastructure requires careful planning and coordination to ensure compatibility and reliability. Grid operators must consider factors such as grid stability, voltage regulation, and system resilience when deploying and operating storage assets.
Grid
Flexibility and Resilience: Energy storage systems can enhance grid flexibility
and resilience by providing fast-response capabilities for frequency
regulation, voltage support, and grid balancing. This can help improve overall
grid reliability and reduce the need for costly investments in traditional grid
infrastructure upgrades.
Renewable
Energy Integration: Energy storage can facilitate the integration of renewable
energy sources by storing excess energy during periods of high generation and
releasing it when needed, thereby smoothing out fluctuations and increasing the
reliability of renewable energy systems.
Peak Shaving
and Demand Response: Energy storage systems can help reduce peak demand on the
grid by storing electricity during off-peak hours when prices are low and
discharging it during peak hours when prices are high. This can help alleviate
stress on the grid during periods of high demand and reduce electricity costs
for consumers.
Ancillary
Services: Energy storage systems can provide valuable ancillary services to the
grid, such as frequency regulation, spinning reserve, and black start
capabilities. By participating in ancillary service markets, storage operators
can monetize their assets and contribute to grid stability and reliability.
Decentralization
and Microgrids: Energy storage systems enable decentralization and the creation
of microgrids, which can operate independently or in conjunction with the main
grid. This can improve energy security, reduce transmission losses, and support
local energy resilience in the face of disruptions or disasters.
Overall, while
integrating energy storage systems into the electrical grid presents numerous
challenges, it also offers significant opportunities to enhance grid
flexibility, reliability, and sustainability. Addressing these challenges and
capitalizing on these opportunities will require collaboration among
stakeholders, technological innovation, supportive policies, and continued
investment in research and development.
Q.2 Explain the design
considerations for a flywheel rotor, including material selection, shape, and
balancing techniques. Discuss the factors that affect the maximum achievable
energy storage capacity.
Q.3 Discuss the concept
of redox flow batteries and their advantages over other battery technologies.
Q.4 Discuss the safety
aspects associated with hydrogen energy storage. Explain the measures,
regulations, and best practices implemented to ensure safe storage, handling,
and transportation of hydrogen.
Q.5 a) Compare
different fuel cells based upon efficiency, operating temperature and fuel
used.
b) What are the main
components of a fuel cell? How does a fuel cell generate electricity?
Q.6 What are the
factors need to be considered while designing PCM? What are the different
applications of PCM?
Q.7 Explain the
innovative strategies used for Thermal Solar Energy Storage in buildings to
achieve 3E goals.
Q.8 Compare and
contrast the capital costs and operational costs of pumped-storage hydroelectricity
and lithium-ion battery storage systems. What factors contribute to the cost
differences between these two technologies?
Q.9 Discuss the
economic viability of implementing sensible heat storage systems indifferent
sectors. Analyze the factors that influence the cost- effectiveness and return
on investment of such systems, considering both the initial capital costs and long-term
operational benefits.
Q.10 a) What are the
challenges or limitations associated with implementing LHTES systems?
b) Provide examples of
real-world applications or case studies where LHTES systems have been
successfully implemented.

GUIDELINES FOR IGNOU Assignment MRWE 002023-24
MRWE 002 Solved
Assignment 2024-25 You
will find it useful to keep the following points in mind:
1. Planning: Read the questions carefully. Go through the
units on which they are based. Make some points regarding each question and
then rearrange these in a STATISTICS IN PSYCHOLOGYal order. And please write
the answers in your own words. Do not reproduce passages from the units.
2. Organisation: Be a little more selective and analytic before
drawing up a rough outline of your answer. In an essay-type question, give
adequate attention to your introduction and conclusion. The introduction must
offer your brief interpretation of the question and how you propose to develop
it. The conclusion must summarise your response to the question. In the course
of your answer, you may like to make references to other texts or critics
as this will add some depth to your analysis.
3. Presentation: Once you are satisfied with your
answers, you can write down the final version for submission, writing each
answer neatly and underlining the points you wish to emphasize.
