AmritaWNA has initiated the Amrita Wireless Smart Grid project envisioning a country with reliable and efficient energy system with electricity access for everyone. Smart grid consists of electrical providers, systems of power delivery and smart buildings (customers). To solve the present power crisis, using renewable energies such as solar, and biogas each building is integrated with main grid and the renewable energy generator. If the output power of the hybrid system is more, we can inject this power into the main grid. Thus the Demand Response maintained.
