- 3. INTRODUCTION Now a day, renewable energy is the best form of clean energy due to high penetration of solar and wind energy. In the upgrade system we can integrate renewable energy system to the grid and manage the power supply to every consumer in a smart way. The main challenging task is to storage of energy stability and co-ordinate control of power in large scale. In this smart grid there is a new technology used i.e the two way communication and transmission of information between all parts of the grid. In this technology the problem occurred in a certain section can be detected in faster way. 3
- 4. BATTERY STORAGE MANAGEMENT AND OPTIMIZATION MODEL In normal grid the power supply is not dependent on the weather conditions. we know in winter season a consumer consumes less electricity then in summer season but we can supply same amount of electricity in both the seasons, due to this reason loss of energy occurs. To evacuate this problem we use storage system in smart grid. The sustainable sources like coal and gas will be replaced by the imperishable wind and solar 4
- 5. An important bottleneck of sustainable energy is its fluctuating supply, which rarely runs parallel to demand to overcome this problem the only one solution is storage but it is not an easy one now a days. The way we use to store energy is costly. So we have to develop a new technology to store the energy. Energy management systems (EMSs) and optimization methods are required to effectively and safely utilize energy storage as a flexible grid asset that can provide multiple grid services. 5

- 7. 7 OPTIMIZATION STRATEGIES IN A COST EFFECTIVE MANNER In smart grid the storage is the main thing which is more costly in this project. It is costly because we have to use more number of batteries to store the energy. If we optimize the number of battery or we can use a new technology to store the energy the cost will be optimized. If we use solar and wind in place of coal and gas to generate electricity we can optimize the cost.
- 8. STABILITY AND CO-ORDINATE CONTROL OF POWER IN LARGE SCALE For stability and Co-ordinate control of power system is installed in the grid. After storing all the energy from the different sources after that we can supply the power to the large scale as per the requirement. Let take an example of a large scale industries where but use of smart grid we can supply power. This smart grid can supply power to all electrical equipments of the industry and control without any fluctuation. 8
- 9. 9 For stable flow of electricity we can use a storage system in the smart grid, which provide electricity to all over the industries requirement.
- 10. ADVANTAGE OF SMART GRID OVER NORMAL GRID The conventional grid is having are way communication. But smart grid uses two digital communications. The conventional grid uses centralized generation and smart grid uses distributed generation. The conventional grid will have limited sensors where as smart grid is equipped with sensors throughout. 10
- 11. FUTURE SCOPE The winds spread energy demands are fulfill by smart grids which will make renewable power attainable. We reduce the cost of electricity. We get 24*7 power supply. 11
- 12. CONCLUSION 12 Undoubtedly, the future recognized smart grid and the power generation to be the most power full energy sources. With the utility of renewable energy in the grid, the electric city cost is decreased drastically and their by continuous power supply is obtained. In future the life span of battery will be increased. By using of renewable energies in the grid the cost of the electricity is decreased. We get the power every time.
