In above targets wind and sun based are the commanding renewable energy sources yet because of their discontinuous nature, likewise called as Variable Renewable energy sources (VRES) [20].2.2. Energy security India is expected to grow at 6.7–7.5% [21] for the year 2017–18. for the year 2017–18.
They are the most common energy storage used devices. These types of energy storage usually use kinetic energy to store energy. Here kinetic energy is of two types: gravitational and rotational. These storages work in a complex system that uses air, water, or heat with turbines, compressors, and other machinery.

3 · 3. Thermal energy storage. Thermal energy storage is used particularly in buildings and industrial processes. It involves storing excess energy – typically surplus energy from renewable sources, or waste heat – to be used later for heating, cooling or power generation. Liquids – such as water – or solid material - such as sand or rocks
