Case studies for integration of renewable energy sources in power grid - lessons for India

This article discusses three case studies of renewable energy integration in power grid from the international literature. Case studies in India and Gujarat in particular are discussed. Capacity and energy generation for 2019-20 actual and 2029-30 estimated are provided. Methods of renewable energy integration are discussed in detail. A brief review of energy storage technology is given. It is shown that with the setting up of Green Energy Corridors and Renewable Energy Management Centres, India would be able to integrate planned renewable energy generation without much difficulty. It must be noted that in the next 25 years renewable energy source, including hydro, will only provide 35-40% of electricity generation. Coal will remain the main energy source for power, and oil and gas for transport.
