Aims and academic significance including quality improvement under project
Need of the Project
The International Energy Agency (IEA) report says that electricity consumption in India is expected to increase around 2280 Billion kWh by 2021-22 and around 4500 Billion kWh by 2031-32. It is evident that energy management & energy efficiency and use of renewable energy have an important role to play in national energy strategy and this will become a key part of solution and is likely to play an increasingly important role for augmentation of grid power, providing energy access, reducing consumption of fossil fuels & helping India to pursue its low carbon developmental pathway. Moreover, Tamilnadu has emerged as a major hub for renewable energy based power generation over the last decade. In the present Tamilnadu Energy scenario one-third of its installed capacity comes from renewable energy sources like wind and solar. Harnessing local renewable energy sources could yield important economic development for the state and the country. In order to overcome the above mentioned challenges and to make our electricity grid more secure, reliable highly adaptive, accessible and stable, we are in an urge to move towards sustainable, energy technologies. It is observed as per present scenario, renewable grid capacity has increased more than 5 times in a span of 8 years. Further, inter and trans-disciplinary research contributions are needed to build a sustainable and secured energy system in the state and in the country.

She has published more than 50 papers in peer-reviewed international journals and is an active researcher in her fields of interest.
This team will gain significantly in its capabilities by bringing together the diverse expertise and skills of the academic and also industrial partners. The beneficiaries TANGEDCO and TEDA are owned by Govt. of Tamilnadu. TANGEDCO is involved in promoting the coordinated development of Generation and Distribution of electricity within the state in most efficient and economical manner whereas TEDA is involved in promoting the renewable energy technologies to the community. Larsen & Toubro is a major technology enterprise in the field of engineering, construction, manufacturing, financial services and recently ventured in the field of Renewable Energy conglomerate with global operations.
Aim of the Project
Increasing renewable electricity generation is an essential component to maximize the renewable energy share in the Indian power generation mix. Such a transition is technically feasible, but will require upgrades of old grid systems and new innovative solutions to accommodate the variable nature of renewable energy generation. With the increasing renewable power share, the smart grid technologies in combination with appropriate energy storage technologies is the major solution to transform the electricity grid system to a stable grid infrastructure to support a sustainable energyfuture.
Variable energies such as solar, wind and bio based power have a lack of stability and to avoid short-term fluctuations in power supplied to the grid, a local storage subsystem could be used to provide higher quality and stability in the feed energy. Energy storage systems (ESSs) would be a facilitator of smart grid deployment and such integration would have a “great impact” on the future power grid. The incorporation
of various superior smart communications, monitoring systems and control strategies would make the integration of Energy storage system with Renewable sources feasible for various potential applications.
Further, successful sustainable energy requires smart materials and chemical change in ultra-small and ultrafast regimes. In the search for alternative energy sources, we need to make new discoveries in materials science. We need catalysts to convert feed stocks into fuels, new architectures for better solar cells and materials for advanced energy storage. To effect this change, we must create the materials that will support emergent energy technologies. The high priority of energy makes it important to sustain research & development of materials for energy applications. Also Surface modification plays a vital role in manufacturing technology to enhance the performance of energy generation, transfer and distribution systems.
Specific Objectives
The overall goal of this project is to maximize the renewable power generation integrated with suitable storage technology towards the development of sustainable stable smartgrid.
The specific objectives of the proposed research are as follows.
-
