Green Energy Corridors - Report on Dimensioning of Control Reserves in Southern Region Grid States


Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH (GIZ) has published the report on the study DNV GL has conducted on their behalf of on “Dimensioning of Control Reserves in Southern Region Grid States of India” to assist the Southern Region Power Committee (SRPC) to efficiently integrate the intermittent Renewable Energy (RE) generators into the Indian electricity grid.

India is targeting grid integration of 175 GW from renewable sources by the year 2022. Grid integration of renewables will increase in the future; safe, reliable and economic operation of the grid will be a challenge.

This study on Control Reserves in Southern Region Grid States of India was conducted as part of the Green Energy Corridors project and aims at quantifying the secondary and tertiary control reserve requirements for grid balancing in the southern region (Andhra Pradesh, Karnataka, Kerala, Telangana, and Tamil Nadu) with the consideration of RE capacity addition of southern region states by 2022. With Automatic Generation Control (AGC) still in the pilot phase, short term control reserve is very much essential to balance the electricity grid which becomes a challenging task for planners and operators of power systems.

The objective of this study is to provide specific sets of recommendations to SPRC (implementation agency) for control reserve requirement identification by 2022 in the southern states of India highlighting the following indicators:

• Identification of types of reserves required at southern states of India and at the regional level

• Detail out a methodology for reserve dimensioning

• Dimensioning of State-wise, regional control reserve requirements by 2022 in the southern region

• Quantitative showcasing the benefits of reserve sharing within the existing policy dimensions in India
