An energy-mix model for round-the-clock power supply in a decarbonized electricity generation scenario: case study of South India

There is increasing urgency towards integration of renewable sources into electricity generation so as to minimize greenhouse gas (GHG) emissions. Renewable power are highly specific in prevalence, both regionally and temporally, their utilization at utility scale for round-the-clock supply poses the problem matching capacity demand every instant time. In present work, we propose a model that integrates geographically distributed diverse with spread-out consumption centres electrical energy storage systems through transmission loss models. For regional grid, computes, over given day, minute-by-minute from all districts, extracts hierarchy losses, stores/draws excess in/from variety options. case South Indian Power Grid (catering about 285 million people India), shows 240 GWh new required non-GHG sources.Graphical abstract
