Frequency control refers to the management of the electrical frequency in power systems, typically maintained at 50 or 60 Hertz, depending on the region. It ensures that the supply of electricity matches the demand, preventing blackouts or system failures. This is crucial for the stability of the grid, as fluctuations can lead to equipment damage or inefficient operation. To achieve frequency control, utilities use various methods, including load shedding, frequency regulation, and automatic generation control. These techniques help balance the generation and consumption of electricity in real-time, allowing for a reliable and stable power supply to homes and businesses.
