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.
