Automatic GenerationControl (AGC)

Pilot ScopeThe GTG-RISE Initiative, in collaboration with Karnataka Power Corporation Limited (KPCL) and Karnataka Power Transmission Corporation Limited (KPTCL), is implementing this pilot to enhance the ancillary reserves in Karnataka. The GTG-RISE pilot will assess AGC's ability to provide a secondary response in southern India. The pilot will cover both hydel and renewable power plants and identify technical requirements and compensation mechanisms for those generation units that participate in the AGC secondary reserve market. The key activities under this pilot are enhancement of existing control facilities at two hydro units at Varahi and Sharavathi, one solar power plant at Shivanasamudra and NP-Kunta each, and one wind farm in Karnataka.

Pilot ProgressGTG-RISE has prepared a pre-feasibility report for AGC implementation at the Varahi and Sharavati hydro power plants and the solar power plant at Shivanasamudra. Following approval of KPCL and KPTCL, Grantee(s) for carrying out enhancements of existing energy management systems and communication network at the select pilot generation sites (Varahi and Sharavati Power Plants) has been appointed in December 2018. In addition, based on suggestion from POSOCO, a 250 MW solar plant at NP Kunta (commissioned by NPTC) is selected for the AGC pilot and the selection process for the grantees has been commenced.

OutcomeThe pilot will demonstrate the techno-economic benefits of AGC and aid in the development of a scalable roadmap for the policy makers and regulators for adoption of AGC. The pilot will provide the data to help CERC specify regulations for AGC's phased implementation with accompanying compensation mechanisms.

BackgroundThe Government of India's plan for integration of large quantum of variable renewable energy (VRE) into the power grid presents a number of challenges for power system operators and electricity market participants. Allied with faster scheduling and despatch is the need for harnessing flexibility from all available sources in the grid. The Central Electricity Regulatory Commission (CERC) has outlined a roadmap for adoption of Automatic Generation Control (AGC) in the country to enable secondary control necessary for ancillary services. One of the pilots implemented under USAID's Greening the Grid (GTG)-RISE Initiative is intended to support adoption of AGC for hydro, solar and wind power plants in the southern region.

Greening the Grid (GTG) ProgramGreening the Grid (GTG) Program

India plans to deploy 175 GW of renewable energy (RE) on its power grid by 2022, aimed at strengthening the country's energy security and reducing its carbon intensity. Compared to conventional power, RE options are more variable, less predictable, and often located further from demand centers. Experience with other systems demonstrates that when RE penetration reaches significant levels, the power grid needs the capacity to manage operations to avoid challenges to reliability and affordability of electricity.

Greening the GRID (GTG) Program

USAID’s Greening the Grid (GTG) initiative is a five-year program implemented in partnership with India’s Ministry of Power (MOP) under the Asia EDGE (Enhancing Development and Growth through Energy) Initiative. The GTG initiative supports Government of India (GOI) in managing the issue of large-scale integration of renewable energy (RE) into the Indian power grid. The program combines three components which interact with each other. These include:Ÿ Power system planning reforms and targeted analysis for large RE parks and RE integration pilots implemented by U.S. Department

Of Energy (DOE) laboratoriesŸ Renewable Integration and Sustainable Energy (RISE) initiative to implement innovation pilots, aimed at testing and evaluating

building blocks to improve the integration of REŸ Peer-to-Peer exchanges between U.S.-India system operators (System Operator Partnership) and regulators (India Regulatory

partnership)

Background

Renewable Integration and Sustainable Energy (RISE) Initiative

Central to GTG, is the design, implementation, and scaling of a series of prioritized innovation pilots that support the integration of RE into the grid. As part of the GTG-RISE Initiative, successful deployment and scale-up of the following pilot solutions across the select states will offer new market opportunities for innovative technologies, solutions and services.
