Integration of large scale renewables - an Indian perspective

Conducive policy environment, regulatory framework, fiscal & financial incentives have accelerated development of renewable energy (RE) generation in the country in past few decades. Due to such initiatives, large capacity addition through renewable generation shall continue to take place in future also. However, renewable are characterized by intermittency & variability. Therefore increasing renewable penetration presents numerous challenges to the grid operator as well as system planner. This paper identifies challenges in grid integration of large scale renewable as well as suggests suitable measures to address them. Paper also evolves requirement of other control infrastructure like establishment of Renewable Energy Management Centres (REMC) equipped with advanced forecasting tools as well as Real time measurement/monitoring schemes through WAMS applications, dynamic reactive compensation, Energy Storage to provide balancing services. It also highlights economic potential of renewable generation in deserts and transmissions plan that serve as a road map up to year 2050.
