The transformation of traditional power systems to encompass diverse renewable energy resources is critical in enabling low carbon climate resilient development. To support key climate and development objectives, the Government of India created an ambitious target of 175 GW of installed renewable energy by 2022. Understanding the impacts of scaled up renewable energy expansion on the grid is crucial and requires robust analysis to plan for potential operation and system changes. Within this context, GoI and other key partners, used advanced weather and power systems modeling to understand grid integration actions required to support these renewable energy targets. Listed below are actions and good practices supporting advanced modeling techniques for smart grid solutions in India, as profiled in the case study.
