What is Automatic Generation Control (AGC) ?
A utomatic Generation Control (AGC) is a system used in power grids to automatically adjust the output of multiple generators in real-time to maintain the balance between electricity supply and demand, and to keep system frequency and inter-area power flows within desired limits. 🔧 Key Functions of AGC: Frequency Regulation : Maintains grid frequency close to nominal (e.g., 50 Hz in India). Load Balancing : Adjusts generation to match real-time demand. Tie-Line Control : Manages power exchange between different control areas or regions. Automatic Dispatch : Sends control signals to generators to increase or decrease output. ⚙️ How AGC Works: AGC receives real-time data from grid sensors (SCADA systems). It compares actual frequency and tie-line flows with scheduled values. Based on deviations, it sends signals to participating generators to adjust their output. This happens every few seconds to maintain grid stability. 🌐 AGC in India: AGC implementation is part of I...
